Using the grass seed calculator - example

For a rectangular lawn that is 10 m wide and 10 m long, the area is 100 m².

If the seed coverage rate is 2.5 kg per 1000 m², the required seed is 100 x 2.5 / 1000 = 0.25 kg.

What is the coverage rate?

Coverage rate is the amount of seed recommended for a known lawn area. It can differ for new lawns, overseeding, grass variety, climate, and soil conditions.

Use the rate printed on the seed package when available, and consider buying a small buffer for uneven spreading or irregular lawn edges.
