Find the square footage of a room and how many boxes of flooring or tile to buy. Nothing leaves your browser.
Area = length × width. Area with waste = area × (1 + waste%). Boxes = area with waste ÷ coverage per box, rounded up.
Multiply length by width in feet. A 12 by 14 ft room is 168 sq ft.
Most installers suggest adding about 10% for cuts and mistakes, more for diagonal or patterned layouts. Change the waste box to match.
Divide the area with waste by the sq ft in one box, then round up. 168 sq ft plus 10% is 184.8 sq ft, which is 10 boxes of 20 sq ft.
Not directly. Split the room into rectangles, calculate each one, and add the areas together.
