Lawn / Turf Calculator

Measure the area (length × width, adding up irregular sections), then add 5–10% for cutting to fit edges and curves. A 400 sq ft (37 m²) lawn ordered at 5% waste is 420 sq ft (39 m²) of sod — most suppliers sell by the square foot, by the piece (about 2.75 sq ft each) or by the pallet (around 450 sq ft / 50 yd²).

Split it into rectangles and triangles, calculate each, and add them up — the calculator’s extra-area field is for exactly that. For curves, measure to the widest point and let the waste allowance absorb the trimming; offcuts rarely re-lay well.

A weed-free, levelled bed of about 4 in (100 mm) of good topsoil, raked to a fine tilth and lightly firmed. Lay the sod brick-fashion with tight joints on the same day it arrives — sod is perishable and cooks on the pallet in summer — then roll and water immediately.

Daily (or twice daily in heat) for the first two weeks, keeping the soil beneath moist — lift a corner to check. Taper off from week three to encourage roots downward. Skip the first mow until the sod resists a gentle tug, then cut high.

A thin sandy-compost layer (0.5–0.75 in / 10–20 mm) brushed over new or established lawn to level hollows, cover joints and feed the grass. For new sod, about 1.3 cubic yards (1 m³) dresses 540–1,080 sq ft (50–100 m²) depending on depth — the calculator shows the volume for your area.
