Standard Sizes

Size & Fit Information

Any door size not shown in this chart is considered a custom size. Availability of standard sizes may vary by manufacturer, and not all door styles are offered in every standard size (for example, panel doors are typically limited to select sizes).

Actual door dimensions are slightly undersized from the nominal size to allow for proper clearance and undercut — typically 1/4″ less in width and 7/8″ less in height.
Example: A 3070 door (3’0″ x 7’0″) will have an actual size of 35-3/4″ x 83-1/8″.

All standard doors are manufactured at 1-3/4″ thickness unless otherwise specified.
