Basis: Manufacturer specifications (Texas Department of Motor Vehicles, State of Ohio)

Overall (mm): length 304.8, width 152.4, height 0.69
- US passenger, truck and trailer plates are 12 × 6 in with four bolt holes on a 7 × 4 3/4 in pattern (Texas and Ohio specifications agree).
- Texas uses elongated 1/2 × 0.28 in slots; the file models them as round 0.28 in (7.11 mm) holes at the slot centres, so the slot length is not modelled.
- Corner radius is not published and is not modelled.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
