Draw your room, then type each wall's exact feet and inches — even an L-shape or odd room — and get the square footage. Or just enter length and width.
For a plain rectangular room, square footage = length × width in feet: a 12 × 10 room is 120 sq ft. The tricky part is odd and L-shaped rooms — and that's what the draw tool is for. You've already measured the walls with a tape, so trace the shape, type each wall in feet and inches, and it adds up the true area for you.
In Draw the room, tap around the outline, then enter each wall's exact length — the tool uses the surveyor's "shoelace" formula, so bays, nooks and L-shapes just work, right down to the inch. In Enter dimensions, split the room into rectangles and add each one's length and width (feet and inches), and they're summed for you.
Measure the area first, then buy extra for cuts and overages. For tile or any hardwood floor, order 10–15% more than the measured square footage — more for diagonal layouts or busy rooms with lots of corners. Every result on this page shows that 10–15% overage amount so you know what to actually order.
This is a measuring aid, not a construction spec — always double-check critical measurements with a tape. The draw tool computes area from the walls you trace and the exact lengths you type; the closing wall connects back to your start, so if your typed lengths don't quite close the loop you'll see it in the shape.
