Calculate room area from length and width. Estimate square footage for one room or multiple rooms, subtract excluded areas, add waste, and estimate flooring, tile, carpet, paint, material units, and total project cost.
Single room mode:
The calculator multiplies room length by room width to find the floor area.
Multiple rooms mode:
The calculator multiplies the area of one room by the number of same-size rooms.
Known area mode:
The calculator converts a known room area into square feet, square yards, square meters, and material quantities.
Project estimate:
The calculator subtracts excluded area, adds waste, estimates material units, baseboard length, material cost, labor cost, and total cost.
A room area calculator helps estimate square footage for flooring, carpet, tile, paint, rugs, baseboards, underlayment, and room remodeling projects.
It can help calculate room area, perimeter, wall area, square yards, square meters, material units, waste, material cost, labor cost, baseboard cost, and estimated total project cost.
Your result shows room area, area with waste, room perimeter, estimated wall area, square yards, square meters, material units, baseboard cost, material cost, labor cost, and estimated total cost.
Measure the room length and width, then multiply them together. For example, a 12 ft by 10 ft room is 120 square feet.
Calculate the room area, subtract any excluded areas, then add waste for cuts, trimming, and layout. Many flooring projects add 5% to 15% extra.
Add the room length and width together, then multiply by 2. The formula is 2 × (length + width).
Yes. It estimates wall area by multiplying the room perimeter by the room height.
It is exact for the measurements entered, but real project estimates can vary by irregular room shapes, closets, alcoves, openings, waste, and installation method.
