What is the standard interior door size in the US, and can you supply it?

The US standard is 80 in (2032 mm) high, with widths of 24, 28, 30, 32 and 36 in, and 1-3/8 in thickness for interior doors. We manufacture to imperial sizes directly, including pre-hung units, so you do not need to convert from metric on site. Taller 84 in and 96 in doors are available for high-ceiling homes and are increasingly specified in new construction.
