Frequently Asked Questions

How do I measure an irregular room?

Break the room into rectangles, measure each separately, and sum the areas. Closets, alcoves, and bay windows count separately. For L-shaped rooms, two rectangles usually suffice.

How many square feet in an acre?

An acre equals 43,560 square feet, or about the area of an American football field minus the end zones. A square acre measures 208.7 feet on each side.

Square feet vs square footage?

Same thing. 'Square footage' is the noun for the total area measurement; 'square feet' is the unit. Real estate listings use square footage to compare home sizes.
