For rectangle, triangle base, and trapezoid first side

For rectangle and trapezoid second parallel side

For circle — distance from center to edge in feet

For triangle and trapezoid (vertical distance in feet)

Enter to calculate total material cost

Area in Sq Yd:

Rectangle: (L × W) ÷ 9
Circle: (π × r²) ÷ 9
Triangle: ((b × h) ÷ 2) ÷ 9
Trapezoid: (((a + b) ÷ 2) × h) ÷ 9

Conversions:
1 sq yd = 9 sq ft
1 sq yd = 0.836 m²
Rectangle: 20 ft × 15 ft.

Sq ft = 20 × 15 = 300
Sq yd = 300 ÷ 9 = 33.33 sq yd
With 15% waste: 33.33 × 1.15 = 38.33 sq yd
Sq m = 300 × 0.0929 = 27.87 m²
At $4.50/sq yd: 33.33 × $4.50 = $150.00

How do I calculate square yards of an area?

For a rectangular area: Measure length and width in feet. Multiply to get square feet, then divide by 9 to get square yards. Formula: Square Yards = (Length × Width) ÷ 9. Example: 20 ft × 15 ft = 300 sq ft ÷ 9 = 33.33 sq yd. For circles: Area = π × r² (in ft) ÷ 9 for sq yd. For triangles: Area = (base × height) ÷ 2 (in ft) ÷ 9. Always convert all measurements to feet first, then calculate area and convert to square yards.

How many square yards are in a typical lawn?

Average lawn sizes in square yards: Small urban lot: 150-300 sq yd, Suburban lot: 400-800 sq yd, Large suburban: 900-1,800 sq yd, Rural/Acreage: 2,400+ sq yd. For reference: A standard 1/4 acre lot (10,890 sq ft) provides about 1,210 sq yd of total area, though not all is lawn. A 50 ft × 100 ft lot = 5,000 sq ft ÷ 9 = 556 sq yd. For sod or turf ordering: measure only the area to be covered, subtract house, driveway, patios, and garden beds.

What materials are sold by the square yard?

Common materials sold per square yard: Carpet (standard pricing unit), Sod/turf, Artificial grass, Fabric (upholstery, outdoor), Vinyl flooring (sheet), Concrete (some regions price per sq yd for slabs), Paint (coverage often stated in sq yd per gallon), Landscaping fabric, Weed barrier, and some tile types. Always confirm the pricing unit — confusing square yards with square feet results in 9x order errors. Check package labels for coverage area in sq yd. Most US flooring retailers quote in sq yd, while big box stores may use sq ft.

How do I convert between square yards, square feet, and square meters?

Conversion reference: 1 square yard = 9 square feet. 1 square yard = 0.836 square meters. 1 square meter = 1.196 square yards. Formulas: Sq ft → Sq yd: divide by 9. Sq yd → Sq ft: multiply by 9. Sq m → Sq yd: multiply by 1.196. Sq yd → Sq m: multiply by 0.836. Quick estimate: 100 sq ft ≈ 11.1 sq yd. 100 sq m ≈ 119.6 sq yd. For construction estimates, use dedicated conversion calculators to avoid costly math errors. Always double-check your conversions before ordering materials.
