Square Foot Calculator

Calculating square footage is essential for various projects, from home renovations to real estate transactions. Our square foot calculator makes this task quick and easy. Whether you’re planning to paint a room, install new flooring, or estimate property value, knowing how to calculate and use square footage is crucial.

How to Use the Square Foot Calculator

  1. Enter the length of the area in feet.
  2. Enter the width of the area in feet.
  3. Click “Calculate” to get the result in square feet.

For irregular shapes, break the area into rectangles and triangles, calculate each separately, and sum the results.

Understanding Square Footage

Square footage is the two-dimensional area of a space measured in square feet. It’s calculated by multiplying the length by the width of a rectangular area. For example, a room that is 10 feet long and 12 feet wide has an area of 120 square feet (10 x 12 = 120).

Common Uses for Square Footage Calculations

  • Home renovations (flooring, painting, wallpapering)
  • Real estate listings and property valuations
  • Construction project planning
  • Landscaping and lawn care
  • Determining heating and cooling requirements

How to Measure for Square Footage

To ensure accurate measurements:

  1. Use a tape measure or laser measuring tool.
  2. Measure to the nearest inch for precision.
  3. For rooms, measure from wall to wall at floor level.
  4. Exclude non-living spaces like unfinished basements or garages unless specified.

Converting Between Units

Our calculator provides results in square feet, but you may need to convert to other units. Here’s a quick reference:

  • 1 square foot = 0.093 square meters
  • 1 square foot = 144 square inches
  • 1 square yard = 9 square feet

Tips for Accurate Square Footage Calculations

  • For L-shaped rooms, divide into rectangles and calculate separately.
  • Include closets and built-in storage in room measurements.
  • For staircases, measure the base area they occupy.
  • Round your final calculations to two decimal places for precision.
