Frequently Asked Questions
How tall is a standard door in feet?
A standard door is 80 inches tall, which is 6 feet 8 inches (203 cm). This has been the US norm for decades because it suits the most common 8-foot ceiling height.
What is the usable clear height of an 80-inch door?
Less than 80 inches. The finished flooring, threshold, and any door sweep eat into the opening, so plan on a few inches less than 80 inches of actual clear pass-through — especially for tall items carried upright.
Are taller doors available?
Yes. 84-inch (7 ft) and 96-inch (8 ft) doors are increasingly common in homes with 9–10 ft ceilings. An 8-foot door accommodates nearly all residential furniture upright, so vertical clearance is rarely a problem with them.
Why does a tall item need more than 80 inches of clearance?
Tall furniture and appliances near 80 inches usually must be tilted at an angle to pass, and tilting increases the effective height needed. The diagonal of the doorway, not the 80-inch vertical, is often the true constraint.
