A standard interior door is typically about 80 inches tall, which is 6 feet 8 inches (around 203 cm).

In many modern homes and offices, this 80‑inch height is the common default for both interior and exterior doors.

You’ll also see taller options like 84 inches (7 feet) or 96 inches (8 feet) in spaces with higher ceilings or custom designs, but those are considered oversized rather than standard.
