How to Use This Grass Seed Calculator
Using this grass seed calculator is dead easy!
- Choose your lawn shape, either from a square/rectangle, a circle or a triangle
- Enter the dimensions of your lawn
- It’ll then tell you how many square meters your lawn is and how much grass seed you need. Either sowing a new lawn (35g of seed per square metre) or overseeding an existing lawn (25g of seed per square metre)
That said, if your lawn is an irregular shape, a grass seed calculator isn’t much use. In which case you’ll have to measure your lawn using this method.
