Square footage is simply length times width. For L-shaped or irregular rooms, split the space into rectangles, calculate each, and add them up — the 'number of areas' field helps when they're identical. Multiply by a price per square foot to budget flooring, tile, paint, or rent.
How it’s calculated
Area = length × width × number of areas. 1 sq yard = 9 sq ft; 1 sq metre ≈ 10.76 sq ft.

Worked example
A 12x10 room is 120 sq ft, about 13.3 sq yards; add a price per sq ft for material cost.
Common mistakes

- Measuring a room for flooring, tile, or paint.
- Pricing material or rent by the square foot.
