The city reached its peak in 450 CE, when it was the center of a powerful culture whose influence extended through much of the Mesoamerican region.
At its peak, the city covered over 30 km² (over ​11 ¹⁄₂ square miles), and perhaps housed a population of 150,000 people, with one estimate reaching as high as 250,000.
Various districts in the city housed people from across the Teotihuacano region of influence, which spread south as far as Guatemala.
Notably absent from the city are fortifications and military structures.

The nature of political and cultural interactions between Teotihuacan and the centers of the Maya region (as well as elsewhere in Mesoamerica) has been a long-standing and significant area for debate.
Substantial exchange and interaction occurred over the centuries from the Terminal Preclassic to the Mid-Classic period. "
Teotihuacan-inspired ideologies" and motifs persisted at Maya centers into the Late Classic, long after Teotihuacan itself had declined.
However, scholars debate the extent and degree of Teotihuacano influence.
Some believe that it had direct and militaristic dominance; others that adoption of "foreign" traits was part of a selective, conscious, and bi-directional cultural diffusion.
New discoveries have suggested that Teotihuacan was not much different in its interactions with other centers from the later empires, such as the Toltec and Aztec.
It is believed that Teotihuacan had a major influence on the Preclassic and Classic Maya, most likely by conquering several Maya centers and regions, including Tikal and the region of Peten, and influencing Maya culture.

Architectural styles prominent at Teotihuacan are found widely dispersed at a number of distant Mesoamerican sites, which some researchers have interpreted as evidence for Teotihuacan's far-reaching interactions and political or militaristic dominance.
A style particularly associated with Teotihuacan is known as talud-tablero, in which an inwards-sloping external side of a structure (talud) is surmounted by a rectangular panel (tablero).
Variants of the generic style are found in a number of Maya region sites, including Tikal, Kaminaljuyu, Copan, Becan, and Oxkintok, and particularly in the Petén Basin and the central Guatemalan highlands.
The talud-tablero style pre-dates its earliest appearance at Teotihuacan in the Early Classic period; it appears to have originated in the Tlaxcala-Puebla region during the Preclassic.
Analyses have traced the development into local variants of the talud-tablero style at sites such as Tikal, where its use precedes the 5th-century appearance of iconographic motifs shared with Teotihuacan.
The talud-tablero style disseminated through Mesoamerica generally from the end of the Preclassic period, and not specifically, or solely, via Teotihuacano influence.
It is unclear how or from where the style spread into the Maya region.
During the zenith main structures of the site, including the pyramids, were painted in dark-red (maroon to Burgundy) colors (only small spots remain now) and were a very impressionable view.

The city was a center of industry, home to many potters, jewelers, and craftsmen.
Teotihuacan is known for producing a great number of obsidian artifacts.
No ancient Teotihuacano non-ideographic texts are known to exist (or known to have existed).
Inscriptions from Maya cities show that Teotihuacan nobility traveled to, and perhaps conquered, local rulers as far away as Honduras.
Maya inscriptions note an individual nicknamed by scholars as "Spearthrower Owl", apparently ruler of Teotihuacan, who reigned for over 60 years and installed his relatives as rulers of Tikal and Uaxactun in Guatemala.

Scholars have based interpretations about the culture at Teotihuacan on archaeology, the murals that adorn the site (and others, like the Wagner Murals, found in private collections), and hieroglyphic inscriptions made by the Maya describing their encounters with Teotihuacano conquerors.
The creation of murals, perhaps tens of thousands of murals, reached its height between 450 and 650.
