Is a 30x30 room big?

At 900 square feet, a 30x30 room is a space bigger than most single rooms. It clears the 70 square foot minimum the International Residential Code sets for a habitable room, so size alone won't stop it from counting as a bedroom. The minimum bedroom size rules also require a 7-foot minimum width and an escape window.

Square rooms are easy to furnish because every wall is the same length, so the bed or sofa can go on whichever wall has no door or window.

For context, compare it with the average bedroom size, or look at rooms close to it: a 25x25 room is 625 square feet and a 25x30 room is 750.
