Square Yard Calculator
Plan your home & garden project with our free square yard calculator. Get precise measurements, material lists, and budgets.
Formula
Square Yards = Square Feet / 9; Square Feet = Length (ft) x Width (ft)
Since one yard equals three feet, one square yard equals 3 times 3 which is 9 square feet. Divide any area in square feet by 9 to convert to square yards. For dimensions, multiply length by width in feet to get square feet first, then divide by 9.
Worked Examples
Example 1: Living Room Carpet
Problem: A living room measures 20 ft x 15 ft. How many square yards of carpet are needed?
Solution: Area = 20 x 15 = 300 sq ft\nSquare yards = 300 / 9 = 33.33 sq yd\nRound up to 34 sq yd for ordering
Result: 33.33 square yards (order 34)
Example 2: Lawn Turf Conversion
Problem: A landscaper quotes 150 square yards of turf. What area does that cover in square feet?
Solution: Square feet = 150 x 9 = 1,350 sq ft\nEquivalent to about 125.4 square meters
Result: 1,350 square feet
Frequently Asked Questions
How many square feet are in a square yard?
There are exactly 9 square feet in one square yard. A square yard is a 3-foot by 3-foot area, and 3 times 3 equals 9. To convert square feet to square yards, divide by 9. To convert square yards to square feet, multiply by 9. This conversion is essential when buying carpet, turf, or other flooring materials that are often priced per square yard.
How do I convert square feet to square yards?
Divide the number of square feet by 9 to get square yards. For example, a 300 square foot room is 300 divided by 9 which equals 33.33 square yards. Remember that you are dividing by 9 (not 3) because you are converting an area measurement, not a linear measurement. Both dimensions of the area are being converted from feet to yards simultaneously.
Why is carpet sold in square yards?
Carpet has traditionally been manufactured, warehoused, and sold in square yard units in the United States. Standard carpet roll widths are 12 feet (4 yards) or 15 feet (5 yards), making square yard calculations convenient for the industry. Some retailers now also list prices per square foot for easier consumer comparison. When comparing prices, always convert to the same unit to make accurate comparisons between products.
How do I calculate the square yardage of a room?
Measure the room length and width in feet, multiply them together to get square feet, then divide by 9 to convert to square yards. For an irregularly shaped room, divide it into rectangles, calculate each section separately, and add them together. Always round up when ordering materials to ensure you have enough to cover the full area plus waste from seams and cuts.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
