Standard Exterior Door Sizes.

Standard US exterior door dimensions are 36 inches wide by 80 inches tall (3-0 x 6-8 in trade callout) for single entry doors, and 60 or 72 inches wide by 80 inches tall (5-0 or 6-0 x 6-8) for double entry doors. Anything outside those dimensions is custom and runs on lead time. Most pre-2010 US homes built to code have rough openings sized for these standards, so a replacement door fits the existing opening with no reframing.

Width and height standards.

Single entry: 32, 34, 36 inches wide (3-0 = 36) with 36 the dominant standard. Height 80 inches (6-8). 84 inches (7-0) is the next standard up; common in new construction post-2010.

Double entry: 60 inches (5-0, two 30-inch panels), 64 inches (5-4, two 32-inch panels), 72 inches (6-0, two 36-inch panels) total width. Height same as single, typically 80 or 84 inches.

Patio sliding: 60, 72, 96, 120 inches total width in 2-panel through 4-panel configurations. Height 80 inches standard, 96 inches in upmarket builds.


When custom kicks in.

Oversized openings (wider than 6-0 single, taller than 7-0, any pivot panel) are custom. Aluminum pivot doors typically run 4-0 to 5-0 wide and 8-0 to 10-0 tall; that is well outside any standard. Bifold and lift-slide oversized openings are entirely custom.

Renovation projects on pre-1950 homes often have non-standard openings (33 inch width is common, height varies). Always measure the rough opening before assuming standard sizing.


Common questions.

What is the standard exterior door size?
Standard US single exterior door is 36 inches wide by 80 inches tall (3-0 x 6-8). Standard double is 60 to 72 inches wide by 80 inches tall.
Are oversized exterior doors more expensive?
Yes. Anything outside the 36 x 80 single standard runs on custom lead time and pricing. Oversized doors need heavier hardware, reinforced frames, and often special hinges, which compounds cost. Factory-direct narrows the premium versus retail custom.
Can I get a non-standard exterior door size?
Yes. All Crateworks exterior doors are built to order, so non-standard widths and heights are not a separate product line; you specify the dimension and we build to it.

Working with a non-standard opening?

Send the rough opening dimensions. We build to order, so non-standard is the same lead time as standard.
