Steel Door Sizes Guide

Steel entry doors are available in a range of single- and double-door dimensions. The best size depends on the project opening, desired proportions, frame system, swing, sidelights, and installation conditions.

Popular size categories at USA Builders Depot

Nominal size is not the same as rough opening

A listed door size should not automatically be treated as the required framed opening. Confirm the exact frame dimensions and installation requirements for the selected model.

Single versus double steel doors

Single doors are often used for standard residential entries and narrower openings. Double doors can create wider clear openings and stronger architectural proportions, but require additional confirmation of active/passive leaf configuration, hardware, and opening conditions.

Custom sizing

Custom Crafted steel doors can support additional dimensions and configurations, subject to engineering, production limits, and final specification approval. Custom lead times typically differ from in-stock products.
