This is a quick square yard calculator for simple areas. Volume and material costs belong in separate trade or volume calculators.
How to use this calculator
- 01Choose area from dimensions, square feet conversion, triangle, or circle.
- 02Enter dimensions in feet and extra inches, or enter a known square-foot area.
- 03Read square yards as the primary result.
- 04Use the square feet, square meters, and acres rows when you need a quick conversion.
If you need square feet first, use the Square Footage Calculator. For metric-first area inputs, use the Square Meter Calculator. Square yards are area. If you need volume from area and depth, use the Cubic Yard Calculator.
Understanding the math
Square yards measure area. Convert feet-and-inches dimensions to feet first, calculate square feet, then divide by 9.
rectangle_sq_yards = length_ft x width_ft / 9 square_yards = square_feet / 9 triangle_sq_yards = base_ft x height_ft / 2 / 9 circle_sq_yards = pi x (diameter_ft / 2)^2 / 9 square_feet = square_yards x 9 square_meters = square_yards x 0.83612736 acres = square_yards / 4840

Frequently asked questions
How to calculate square yards?
For a rectangle, multiply length by width in feet to get square feet, then divide by 9.
How to calculate square feet to square yards?
Divide square feet by 9. For example, 120 sq ft / 9 = 13.33 sq yd.
How many square feet are in a square yard?
One square yard equals 9 square feet.
How many square yards are in a 10x12 room?
A 10x12 room is 120 sq ft. Divide 120 by 9 to get 13.33 sq yd.
Does this calculator show square meters too?
Yes. Square yards stay primary, and the result also shows square meters as a conversion. For metric-first inputs, use the Square Meter Calculator.
