Select an item below for a quick check, or enter custom dimensions to test any doorway clearance.
This calculator determines if furniture, appliances, and large items will fit through standard doorways. We account for door frame width, door swing clearance, and diagonal tilt strategies—covering interior doors, exterior entries, and narrow hallways.

Standard interior doorways are 32 inches wide (clear opening), while exterior doors are typically 36 inches. Building codes require a minimum clear opening of 32 inches for accessibility.
Door trim (casing) typically protrudes 0.5 to 1 inch on each side of the frame. This means a 36-inch nominal door may only have 34–35 inches of usable clearance.
Yes — removing the door from its hinges adds roughly 1.5 to 2 inches of extra width. The hinge pins usually pop out with a screwdriver and hammer.
Try tilting or rotating the item at an angle. You can also remove the door for extra width. If it still won't fit, check for wider entry points like patio doors or sliding glass doors.
Yes — the hallway in front of the door determines your turning radius. A narrow hallway limits how much you can angle a large item to get it through the opening.
Check clear opening vs. item dimensions — straight, tilted, or hinged orientations.
