Justice Rehnquist
delivered the opinion of the Court.
We granted certiorari to consider the constitutionality, under the Due Process Clause of the Fourteenth Amendment and the jury trial guarantee of the Sixth Amendment, of Pennsylvania's Mandatory Minimum Sentencing Act, 42 Pa. Cons. Stat. §9712 (1982) (the Act).
I
The Act was adopted in 1982. It provides that anyone convicted of certain enumerated felonies is subject to a mandatory minimum sentence of five years' imprisonment if the sentencing judge finds, by a preponderance of the evidence, that the person "visibly possessed a firearm" during the commission of the offense. At the sentencing hearing, the judge is directed to consider the evidence introduced at trial and any additional evidence offered by either the defendant or the Commonwealth. § 9712(b). The Act operates to divest the judge of discretion to impose any sentence of less than five years for the underlying felony; it does not authorize a sentence in excess of that otherwise allowed for that offense.
Each petitioner was convicted of, among other things, one of § 9712's enumerated felonies. Petitioner McMillan, who shot his victim in the right buttock after an argument over a debt, was convicted by a jury of aggravated assault. Petitioner Peterson shot and killed her husband and, following a bench trial, was convicted of voluntary manslaughter. Petitioner Dennison shot and seriously wounded an acquaintance and was convicted of aggravated assault after a bench trial. Petitioner Smalls robbed a seafood store at gunpoint; following a bench trial he was convicted of robbery. In each case the Commonwealth gave notice that at sentencing it would seek to proceed under the Act. No § 9712 hearing was held, however, because each of the sentencing judges before whom petitioners appeared found the Act unconstitutional; each imposed a lesser sentence than that required by the Act.
The Commonwealth appealed all four cases to the Supreme Court of Pennsylvania. That court consolidated the appeals and unanimously concluded that the Act is consistent with due process. Commonwealth v. Wright, 508 Pa. 25, 494 A. 2d 354 (1985). Petitioners' principal argument was that visible possession of a firearm is an element of the crimes for which they were being sentenced and thus must be proved beyond a reasonable doubt under In re Winship, 397 U. S. 358 (1970), and Mullaney v. Wilbur, 421 U. S. 684 (1975). After observing that the legislature had expressly provided that visible possession "shall not be an element of the crime," §9712(b), and that the reasonable-doubt standard "'has always been dependent on how a state defines the offense' " in question, 508 Pa., at 34, 494 A. 2d, at 359, quoting Patterson v. New York, 432 U. S. 197, 211, n. 12 (1977), the court rejected the claim that the Act effectively creates a new set of upgraded felonies of which visible possession is an "element." Section 9712, which comes into play only after the defendant has been convicted of an enumerated felony, neither provides for an increase in the maximum sentence for such felony nor authorizes a separate sentence; it merely requires a minimum sentence of five years, which may be more or less than the minimum sentence that might otherwise have been imposed. And consistent with Winship, Mullaney, and Patterson, the Act "creates no presumption as to any essential fact and places no burden on the defendant"; it "in no way relieve[s] the prosecution of its burden of proving guilt." 508 Pa., at 35, 494 A. 2d, at 359.
Petitioners also contended that even if visible possession is not an element of the offense, due process requires more than proof by a preponderance of the evidence. The Supreme Court of Pennsylvania rejected this claim as well, holding that the preponderance standard satisfies due process under the approach set out in Addington v. Texas, 441 U. S. 418 (1979). The Commonwealth's interest in deterring the illegal use of firearms and in sure punishment for those who commit crimes with guns is as compelling as a convicted defendant's contervailing liberty interest, which has been substantially diminished by a guilty verdict. Moreover, the risk of error in the context of a § 9712 proceeding is comparatively slight — visible possession is a simple, straightforward issue susceptible of objective proof. On balance, the court concluded, it is reasonable for the defendant and the Commonwealth to share equally in any risk of error. The court vacated petitioners' sentences and remanded for sentencing pursuant to the Act. One justice concurred and filed a separate opinion.
We granted certiorari, 474 U. S. 815 (1985), and now affirm.

Petitioners argue that under the Due Process Clause as interpreted in Winship and Mullaney, if a State wants to punish visible possession of a firearm it must undertake the burden of proving that fact beyond a reasonable doubt. We disagree. Winship held that "the Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged." 397 U. S., at 364. In Mullaney v. Wilbur, we held that the Due Process Clause "requires the prosecution to prove beyond a reasonable doubt the absence of the heat of passion on sudden provocation when the issue is properly presented in a homicide case." 421 U. S., at 704. But in Patterson we rejected the claim that whenever a State links the "severity of punishment" to "the presence or absence of an identified fact" the State must prove that fact beyond a reasonable doubt. 432 U. S., at 214; see also id., at 207 (State need not "prove beyond a reasonable doubt every fact, the existence or nonexistence of which it is willing to recognize as an exculpatory or mitigating circumstance affecting the degree of culpability or the severity of the punishment"). In particular, we upheld against a due process challenge New York's law placing on defendants charged with murder the burden of proving the affirmative defense of extreme emotional disturbance.
Patterson stressed that in determining what facts must be proved beyond a reasonable doubt the state legislature's definition of the elements of the offense is usually dispositive: "[T]he Due Process Clause requires the prosecution to prove beyond a reasonable doubt all of the elements included in the definition of the offense of which the defendant is charged." Id., at 210 (emphasis added). While "there are obviously constitutional limits beyond which the States may not go in this regard," ibid., "[t]he applicability of the reasonable-doubt standard . . . has always been dependent on how a State defines the offense that is charged in any given case," id., at 211, n. 12. Patterson rests on a premise that bears repeating here:
"It goes without saying that preventing and dealing with crime is much more the business of the States than it is of the Federal Government, Irvine v. California, 347 U. S. 128, 134 (1954) (plurality opinion), and that we should not lightly construe the Constitution so as to intrude upon the administration of justice by the individual States. Among other things, it is normally 'within the power of the State to regulate procedures under which its laws are carried out, including the burden of producing evidence and the burden of persuasion,' and its decision in this regard is not subject to proscription under the Due Process Clause unless 'it offends some principle of justice so rooted in the traditions and conscience of our people as to be ranked as fundamental.' Speiser v. Randall, 357 U. S. 513, 523 (1958)." Id., at 201-202 (citations omitted).
We believe that the present case is controlled by Patterson, our most recent pronouncement on this subject, rather than by Mullaney. As the Supreme Court of Pennsylvania observed, the Pennsylvania Legislature has expressly provided that visible possession of a firearm is not an element of the crimes enumerated in the mandatory sentencing statute, § 9712(b), but instead is a sentencing factor that comes into play only after the defendant has been found guilty of one of those crimes beyond a reasonable doubt. Indeed, the elements of the enumerated offenses, like the maximum permissible penalties for those offenses, were established long before the Mandatory Minimum Sentencing Act was passed. While visible possession might well have been included as an element of the enumerated offenses, Pennsylvania chose not to redefine those offenses in order to so include it, and Patterson teaches that we should hesitate to conclude that due process bars the State from pursuing its chosen course in the area of defining crimes and prescribing penalties.
As Patterson recognized, of course, there are constitutional limits to the State's power in this regard; in certain limited circumstances Winship's reasonable-doubt requirement applies to facts not formally identified as elements of the offense charged. Petitioners argue that Pennsylvania has gone beyond those limits and that its formal provision that visible possession is not an element of the crime is therefore of no effect. We do not think so. While we have never attempted to define precisely the constitutional limits noted in Patterson, i. e., the extent to which due process forbids the reallocation or reduction of burdens of proof in criminal cases, and do not do so today, we are persuaded by several factors that Pennsylvania's Mandatory Minimum Sentencing Act does not exceed those limits.
We note first that the Act plainly does not transgress the limits expressly set out in Patterson. Responding to the concern that its rule would permit States unbridled power to redefine crimes to the detriment of criminal defendants, the Patterson Court advanced the unremarkable proposition that the Due Process Clause precludes States from discarding the presumption of innocence:
" '[I]t is not within the province of a legislature to declare an individual guilty or presumptively guilty of a crime.' McFarland v. American Sugar Rfg. Co., 241 U. S. 79, 86 (1916). The legislature cannot 'validly command that the finding of an indictment, or mere proof of the identity of the accused, should create a presumption of the existence of all the facts essential to guilt.' Tot v. United States, 319 U. S. 463, 469 (1943)." Patterson, 432 U. S., at 210.
Here, of course, the Act creates no presumptions of the sort condemned in McFarland v. American Sugar Rfg. Co., 241 U. S. 79 (1916) (presumption from price sugar refiner paid for sugar that refiner was party to a monopoly), or Tot v. United States, 319 U. S. 463 (1943) (presumption that convicted felon who possessed a weapon obtained it in interstate commerce). Nor does it relieve the prosecution of its burden of proving guilt; § 9712 only becomes applicable after a defendant has been duly convicted of the crime for which he is to be punished.
The Court in Mullaney observed, with respect to the main criminal statute invalidated in that case, that once the State proved the elements which Maine required it to prove beyond a reasonable doubt the defendant faced "a differential in sentencing ranging from a nominal fine to a mandatory life sentence." 421 U. S., at 700. In the present case the situation is quite different. Of the offenses enumerated in the Act, third-degree murder, robbery as defined in 18 Pa. Cons. Stat. § 3701(a)(1) (1982), kidnaping, rape, and involuntary deviate sexual intercourse are first-degree felonies subjecting the defendant to a maximum of 20 years' .imprisonment. § 1103(1). Voluntary manslaughter and aggravated assault as defined in § 2702(a)(1) are felonies of the second degree carrying a maximum sentence of 10 years. § 1103(2). Section 9712 neither alters the maximum penalty for the crime committed nor creates a separate offense calling for a separate penalty; it operates solely to limit the sentencing court's discretion in selecting a penalty within the range already available to it without the special finding of visible possession of a firearm. Section 9712 "ups the ante" for the defendant only by raising to five years the minimum sentence which may be imposed within the statutory plan. The statute gives no impression of having been tailored to permit the visible possession finding to be a tail which wags the dog of the substantive offense. Petitioners' claim that visible possession under the Pennsylvania statute is "really" an element of the offenses for which they are being punished — that Pennsylvania has in effect defined a new set of upgraded felonies — would have at least more superficial appeal if a finding of visible possession exposed them to greater or additional punishment, cf. 18 U. S. C. § 2113(d) (providing separate and greater punishment for bank robberies accomplished through "use of a dangerous weapon or device"), but it does not.
Petitioners contend that this Court's decision in Specht v. Patterson, 386 U. S. 605 (1967), requires the invalidation of the Pennsylvania statute challenged here. Again, we think petitioners simply read too much into one of our previous decisions. Under the Colorado scheme at issue in Specht, conviction of a sexual offense otherwise carrying a maximum penalty of 10 years exposed a defendant to an indefinite term to and including life imprisonment if the sentencing judge made a post-trial finding that the defendant posed "a threat of bodily harm to members of the public, or is an habitual offender and mentally ill," id., at 607. This finding could be made, without notice or any "hearing in the normal sense," based solely on a presentence psychiatric report. Id., at 608. This Court held that the Colorado scheme failed to satisfy the requirements of due process, and that the defendant had a right to be present with counsel, to be heard, to be confronted with and to cross-examine the witnesses against him, and to offer evidence of his own.
Petitioners suggest that had Winshvp already been decided at the time of Specht, the Court would have also required that the burden of proof as to the post-trial findings be beyond a reasonable doubt. But even if we accept petitioners' hypothesis, we do not think it avails them here. The Court in Specht observed that following trial the Colorado defendant was confronted with "a radically different situation" from the usual sentencing proceeding. The same simply is not true under the Pennsylvania statute. The finding of visible possession of a firearm of course "ups the ante" for a defendant, or it would not be challenged here; but it does so only in the way that we have previously mentioned, by raising the minimum sentence that may be imposed by the trial court.
Finally, we note that the specter raised by petitioners of States restructuring existing crimes in order to "evade" the commands of Winship just does not appear in this case. As noted above, § 9712's enumerated felonies retain the same elements they had before the Mandatory Minimum Sentencing Act was passed. The Pennsylvania Legislature did not change the definition of any existing offense. It simply took one factor that has always been considered by sentencing courts to bear on punishment — the instrumentality used in committing a violent felony — and dictated the precise weight to be given that factor if the instrumentality is a firearm. Pennsylvania's decision to do so has not transformed against its will a sentencing factor into an "element" of some hypothetical "offense."
Petitioners seek support for their due process claim by observing that many legislatures have made possession of a weapon an element of various aggravated offenses. But the fact that the States have formulated different statutory schemes to punish armed felons is merely a reflection of our federal system, which demands "[tjolerance for a spectrum of state procedures dealing with a common problem of law enforcement," Spencer v. Texas, 385 U. S. 554, 566 (1967). That Pennsylvania's particular approach has been adopted in few other States does not render Pennsylvania's choice unconstitutional. See Patterson, 432 U. S., at 211; cf. Spaziano v. Florida, 468 U. S. 447, 464 (1984). Nor does the historical test advanced by the Patterson dissent, on which petitioners apparently also rely, materially advance their cause. While it is surely true that "[f]or hundreds of years some offenses have been considered more serious and the punishment made more severe if the offense was committed with a weapon or while armed," Brief for Petitioners 17, n. 11, petitioners do not contend that the particular factor made relevant here — visible possession of a firearm — has historically been treated "in the Anglo-American legal tradition" as requiring proof beyond a reasonable doubt, Patterson, 432 U. S., at 226 (Powell, J., dissenting). See also id., at 229, n. 14 (Powell, J., dissenting) (approving new scheme under which State put burden on armed robbery defendant to prove that gun was unloaded or inoperative in order to receive lower sentence).
We have noted a number of differences between this case and Winship, Mullaney, and Specht, and we find these differences controlling here. Our inability to lay down any "bright line" test may leave the constitutionality of statutes more like those in Mullaney and Specht than is the Pennsylvania statute to depend on differences of degree, but the law is full of situations in which differences of degree produce different results. We have no doubt that Pennsylvania's Mandatory Minimum Sentencing Act falls on the permissible side of the constitutional line.

Having concluded that States may treat "visible possession of a firearm" as a sentencing consideration rather than an element of a particular offense, we now turn to petitioners' subsidiary claim that due process nonetheless requires that visible possession be proved by at least clear and convincing evidence. Like the court below, we have little difficulty concluding that in this case the preponderance standard satisfies due process. Indeed, it would be extraordinary if the Due Process Clause as understood in Patterson plainly sanctioned Pennsylvania's scheme, while the same Clause explained in some other line of less clearly relevant cases imposed more stringent requirements. There is, after all, only one Due Process Clause in the Fourteenth Amendment. Furthermore, petitioners do not and could not claim that a sentencing court may never rely on a particular fact in passing sentence without finding that fact by "clear and convincing evidence." Sentencing courts have traditionally heard evidence and found facts without any prescribed burden of proof at all. See Williams v. New York, 337 U. S. 241 (1949). Pennsylvania has deemed a particular fact relevant and prescribed a particular burden of proof. We see nothing in Pennsylvania's scheme that would warrant constitutionalizing burdens of proof at sentencing.
Petitioners apparently concede that Pennsylvania's scheme would pass constitutional muster if only it did not remove the sentencing court's discretion, i. e., if the legislature had simply directed the court to consider visible possession in passing sentence. Brief for Petitioners 31-32. We have some difficulty fathoming why the due process calculus would change simply because the legislature has seen fit to provide sentencing courts with additional guidance. Nor is there merit to the claim that a heightened burden of proof is required because visible possession is a fact "concerning the crime committed" rather than the background or character of the defendant. Ibid. Sentencing courts necessarily consider the circumstances of an offense in selecting the appropriate punishment, and we have consistently approved sentencing schemes that mandate consideration of facts related to the crime, e. g., Proffitt v. Florida, 428 U. S. 242 (1976), without suggesting that those facts must be proved beyond a reasonable doubt. The Courts of Appeals have uniformly rejected due process challenges to the preponderance standard under the federal "dangerous special offender" statute, 18 U. S. C. § 3575, which provides for an enhanced sentence if the court concludes that the defendant is both "dangerous" and a "special offender." See United States v. Davis, 710 F. 2d 104, 106 (CA3) (collecting cases), cert. denied, 464 U. S. 1001 (1983).
IV
In light of the foregoing, petitioners' final claim — that the Act denies them their Sixth Amendment right to a trial by jury — merits little discussion. Petitioners again argue that the jury must determine all ultimate facts concerning the offense committed. Having concluded that Pennsylvania may properly treat visible possession as a sentencing consideration and not an element of any offense, we need only note that there is no Sixth Amendment right to jury sentencing, even where the sentence turns on specific findings of fact. See Spaziano v. Florida, 468 U. S., at 459.
For the foregoing reasons, the judgment of the Supreme Court of Pennsylvania is affirmed.
It is so ordered.
Section 9712 provides in full:
"(a) Mandatory sentence. — Any person who is convicted in any court of this Commonwealth of murder of the third degree, voluntary manslaughter, rape, involuntary deviate sexual intercourse, robbery as defined in 18 Pa. C. S. § 3701(a)(l)(i), (ii) or (iii) (relating to robbery), aggravated assault as defined in 18 Pa. C. S. § 2702(a)(1) (relating to aggravated assault) or kidnapping, or who is convicted of attempt to commit any of these crimes, shall, if the person visibly possessed a firearm during the commission of the offense, be sentenced to a minimum sentence of at least five years of total confinement notwithstanding any other provision of this title or other statute to the contrary.
"(b) Proof at sentencing. —Provisions of this section shall not be an element of the crime and notice thereof to the defendant shall not be required prior to conviction, but reasonable notice of the Commonwealth's intention to proceed under this section shall be provided after conviction and before sentencing. The applicability of this section shall be determined at sentencing. The court shall consider any evidence presented at trial and shall afford the Commonwealth and the defendant an opportunity to present any necessary additional evidence and shall determine, by a preponderance of the evidence, if this section is applicable.
"(c) Authority of court in sentencing. — There shall be no authority in any court to impose on an offender to which this section is applicable any lesser sentence than provided for in subsection (a) or to place such offender on probation or to suspend sentence. Nothing in this section shall prevent the sentencing court from imposing a sentence greater than that provided in this section. Sentencing guidelines promulgated by the Pennsylvania Commission on Sentencing shall not supersede the mandatory sentences provided in this section.
"(d) Appeal by Commonwealth. — If a sentencing court refuses to apply this section where applicable, the Commonwealth shall have the right to appellate review of the action of the sentencing court. The appellate court shall vacate the sentence and remand the case to the sentencing court for imposition of a sentence in accordance with this section if it finds that the sentence was imposed in violation of this section.
"(e) Definition of firearm. — As used in this section 'firearm' means any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive or the expansion of gas therein."
McMillan was sentenced to a term of 3 to 10 years for aggravated assault; he was also convicted of possession of instruments of crime, 18 Pa. Cons. Stat. § 2503 (1982), for which he received a concurrent term of 27s to 5 years. Peterson received a sentence of 1 to 6 years on the manslaughter charge, as well as a concurrent term of 6 to 18 months for possession of instruments of crime. Dennison received concurrent sentences of ll'A to 23 months for aggravated assault and possession of instruments of crime. Smalls was sentenced to concurrent 4- to 8-year terms for robbery and criminal conspiracy; he was also convicted of violating the Uniform Firearms Act, §6101 et seq., and reckless endangerment, §2705, for which he was sentenced to concurrent terms of 2'A to 5 years and 1 to 2 years respectively. He received a suspended sentence for possession of instruments of crime.
The elements of the enumerated offenses were established in essentially their present form in 1972. See 1972 Pa. Laws No. 334, which compiled, amended, and codified the Pennsylvania "Crimes Code." The Mandatory Minimum Sentencing Act was passed in 1982.
By prescribing a mandatory minimum sentence, the Act incidentally serves to restrict the sentencing court's discretion in setting a maximum sentence. Pennsylvania law provides that a minimum sentence of confinement "shall not exceed one-half of the maximum sentence imposed." 42 Pa. Cons. Stat. § 9756(b) (1982). Thus, the shortest maximum term permissible under the Act is 10 years.
We reject the view that anything in the Due Process Clause bars States from making changes in their criminal law that have the effect of making it easier for the prosecution to obtain convictions. "From the vantage point of the Constitution, a change in law favorable to defendants is not necessarily good, nor is an innovation favorable to the prosecution necessarily bad." Jeffries & Stephan, Defenses, Presumptions, and Burden of Proof in the Criminal Law, 88 Yale L. J. 1325, 1361 (1979).
The Commonwealth argues that the statutes on which petitioners rely typically differ from that at issue here. In particular, most of the statutes are directed at all deadly weapons rather than just firearms, and most treat the armed crime as a higher grade of offense than the unarmed crime. Brief for Respondent 11.
At least two States — New Jersey, see N. J. Stat. Ann. §2C:43-6c (West 1982); State v. Gantt, 186 N. J. Super. 262, 452 A. 2d 477 (1982), aff'd, 195 N. J. Super. 144, 478 A. 2d 422 (App. Div. 1984), and Kansas, see Kan. Stat. Ann. § 21-4618 (1981); State v. Mullins, 223 Kan. 798, 577 P. 2d 51 (1978)—have statutory schemes similar to Pennsylvania's.
Addington v. Texas, 441 U. S. 418 (1979), and Santosky v. Kramer, 455 U. S. 745 (1982), which respectively applied the "clear and convincing evidence" standard where the State sought involuntary commitment to a mental institution and involuntary termination of parental rights, are not to the contrary. Quite unlike the situation in those cases, criminal sentencing takes place only after a defendant has been adjudged guilty beyond a reasonable doubt. Once the reasonable-doubt standard has been applied to obtain a valid conviction, "the criminal defendant has been constitutionally deprived of his liberty to the extent that the State may confine him." Meachum v. Fano, 427 U. S. 215, 224 (1976). As noted in text, sentencing courts have always operated without constitutionally imposed burdens of proof; embracing petitioners' suggestion that we apply the clear-and-convincing standard here would significantly alter criminal sentencing, for we see no way to distinguish the visible possession finding at issue here from a host of other express or implied findings sentencing judges typically make on the way to passing sentence.
