How square footage is calculated
Find floor or surface area from length and width, with a choice of feet or meters and an optional count of identical rectangles. The calculator reports square feet and square meters; split complex spaces into rectangles and add their areas. A 12 ft by 15 ft room has 180 square feet. The calculation validates each input and keeps its stated units explicit. Include each surface you plan to cover, then subtract openings only when their area is material. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
