About This Calculator
The Square Footage Calculator calculates the area of a rectangular space in square feet, square meters, square yards, and acres. It's useful for measuring rooms, properties, land, and any rectangular area for real estate, construction, or interior design projects.
Simply enter the length and width of the area, select your preferred unit system (feet or meters), and the calculator will automatically compute the area in multiple units. This helps you convert between different area measurements easily.
Formula & Calculation Method
Area Calculation:
Square Feet:
Area = Length × Width
(in feet)
Square Meters:
Area = Length × Width
(in meters)
or Square Feet × 0.092903
Square Yards:
Square Yards = Square Feet ÷ 9
Acres:
Acres = Square Feet ÷ 43,560
For rectangular areas, multiply the length by the width to get the area. The calculator automatically converts between different area units using standard conversion factors.

Frequently Asked Questions
How do I calculate square footage?
Multiply the length by the width of the area. For example, a room that is 10 feet long and 12 feet wide has an area of 120 square feet (10 × 12 = 120).
How many square feet are in a square meter?
One square meter equals approximately 10.764 square feet. Conversely, one square foot equals approximately 0.092903 square meters.
How do I convert square feet to acres?
Divide the number of square feet by 43,560 to get acres. For example, 87,120 square feet equals 2 acres (87,120 ÷ 43,560 = 2).
Can I calculate irregular shapes?
This calculator is designed for rectangular areas. For irregular shapes, break the area into rectangles, calculate each separately, and sum the results.
