What This Calculator Does
The Room Area Calculator finds the floor area of a rectangular room from its length and width, reporting both square feet and square meters. It is the first step in any flooring, paint, or tile estimate.
How It Works
Area is length times width for rectangular spaces. The tool multiplies feet directly for square footage and applies the 0.092903 factor to report square meters.
Example
A room 12 feet by 10 feet has an area of 120 square feet, or about 11.15 square meters.
Formula
Area = Length × WidthSquare meters = sq ft × 0.092903.
Reading the Results
Area
The floor surface in square feet, the base number for ordering materials.
Area in Square Meters
The same floor area in metric units for international materials or comparisons.
Frequently Asked Questions
How do I calculate the area of a room?
Measure length and width in the same unit, then multiply. A 12 x 10 foot room is 120 square feet.
How do I measure an L-shaped room?
Split it into two rectangles, compute each area, and add them together. The tool handles one rectangle at a time.
Should I account for waste?
Yes. Add 5-10% for cutting waste when buying flooring, tile, or carpet, which the flooring calculator handles for you.
