Sod & Grass Seed Calculator
Work out how many sod rolls or pallets, or pounds of grass seed, you need for a new lawn from its area, coverage rates and a waste allowance.
關於 Sod & Grass Seed Calculator
The Sod & Grass Seed Calculator sizes a new lawn. Enter up to three rectangular areas — most gardens are easier to measure as a few rectangles than as one odd shape — and the tool totals the area, adds a waste allowance and tells you how many sod rolls or pallets, or how many pounds of grass seed, the job needs.
Sod is sold by the roll and by the pallet, and coverage varies by supplier. A common US roll covers about 9 ft² (0.836 m²) and a pallet around 450 ft² (41.8 m²), but the figures are editable so you can enter exactly what your supplier quotes. Rolls are rounded up to whole units since you cannot buy a fraction of one.
For seeding, rates are entered per 1,000 ft² in imperial or per 100 m² in metric. New lawns typically need 2–3 kg per 100 m² (4–6 lb per 1,000 ft²) depending on the species, while overseeding an existing lawn usually needs about half as much. Always add waste for shaped edges and cuts.
