In total, 13,807 commercial vehicles were inspected during the week. Law enforcement officers handed out 1,243 size and weight citations and 497 warnings, 404 speeding citations and 877 warnings, and 580 seatbelt citations and 112 warnings.
Single (also called Twin) - 38 in Ã 75 in (97 cm Ã 191 cm) Double (also called Full) - 54 in Ã 75 in (137 cm Ã 191 cm) Queen - 60 in Ã 80 in (152 cm Ã 203 cm) King - 76 in Ã 80 in (193 cm Ã 203 cm) After all that, yes, there is a difference, but as to precisely how much, depends on numerous factors. In reference to 'large double' and 'extra large double', my guess is that they are closer to the European or US measurements.
At 53 inches wide, a double mattress is 15 inches wider than a twin, and is suitable for a single sleeper under 5 feet 5 inches in height. A couple that shares a double mattress has 27 inches of space per person, roughly equal to a baby's crib.
