Calculate square inches from length and width, circles, multiple areas, or known area conversions. Convert square inches to square feet, square yards, square meters, square centimeters, and estimate materials, waste, and cost.
Length and width mode:
The calculator converts your dimensions into inches, then multiplies length by width.
Multiple areas mode:
The calculator multiplies one area by the number of same-size areas.
Known area mode:
The calculator converts your known area into square inches, square feet, square yards, square centimeters, and square meters.
Circular area mode:
The calculator uses diameter to estimate circular square inches and perimeter.
A square inches calculator helps estimate small-area projects such as labels, stickers, tiles, craft sheets, signs, panels, fabric cuts, paper cuts, material samples, and small surfaces.
It can help calculate square inches, square feet, square yards, square centimeters, square meters, perimeter, material quantity, waste, material cost, labor cost, and estimated total cost.
Your result shows net square inches, square inches with waste, square feet, square yards, square centimeters, square meters, perimeter, material units, material cost, labor cost, and estimated total cost.
Multiply length in inches by width in inches. For example, a 12 inch by 8 inch piece has 96 square inches.
One square foot equals 144 square inches.
One square yard equals 1,296 square inches.
Divide square inches by 144. For example, 288 square inches equals 2 square feet.
No. It is an estimate. Actual area and material needs can vary by shape, cuts, overlap, trimming, waste, product size, and installation method.
