About This Calculator

Getting the right amount of grass seed is crucial for a successful lawn. Too little seed results in thin, patchy coverage, while too much leads to overcrowding and disease. This calculator helps you determine the optimal amount based on your area and grass type.

How It Works

Enter the area to be seeded, select whether you're starting a new lawn or overseeding, and choose your grass type. The calculator provides the recommended seed amount.
