Square Meter & Square Foot Calculator

Calculate area from length and width, then instantly view both square meters and square feet.

Calculate Your Floor Area in m² and ft²

Type the length and width of each room or zone, then add as many as the job needs for one combined total. Every result is shown in both square meters and square feet — handy when your data sheet uses one and your tape uses the other.

Units
Measure each room or section, then "Add Area" to total them up. Decimals are fine (e.g. 6.5).

How the Square Meter & Square Foot Calculator Works

  1. Select your preferred unit — meters or feet
  2. Enter the length and width of the surface you are measuring
  3. The result shows the area in both m² and ft² instantly
  4. Use Add Area to measure additional rooms or zones — each row calculates independently
  5. The combined total at the bottom gives you the full project area, ready to use in a material estimate

Frequently Asked Questions

How do I calculate square meters?

Multiply the length by the width of the surface. For example, a floor 6 m long and 4 m wide has an area of 24 m².

How many square feet are in a square meter?

1 square meter equals 10.764 square feet. The calculator converts between these units automatically.

Can I calculate multiple rooms at once?

Yes. Use the Add Area button to add as many rooms or zones as needed. Each row calculates independently and the combined total is shown at the bottom.

What is a square meter?

A square meter (m²) is the area of a square that is one meter long on each side. It is the standard unit of floor area in metric countries. One square meter equals 10.764 square feet. To calculate the area of a rectangular room in square meters, multiply the length by the width — both measured in meters.

How does this help with epoxy flooring quotes?

It gives you the total floor area, which you then use alongside the product coverage rate (m²/L or ft²/gal) to calculate how much epoxy, primer, or flake material to order.

Important Notes

  • Measure to the longest point of irregular rooms to avoid underestimating area
  • For L-shaped or irregular floors, split into rectangular sections and use multiple rows
  • Floor area measurements do not account for obstacles such as columns, drains, or machinery bases
  • Use the total area as the input for an epoxy coverage or material quantity calculator
