How to calculate lawn overseeding rate
This calculator finds overseeding rate by scaling a per-1,000-square-foot seed rate to your actual lawn area.
How the calculation works
Seed needed = (Lawn area ÷ 1,000) × Seed rate per 1,000 sq ft.
Example
8,000 sq ft lawn at 5 lb per 1,000 sq ft: (8,000÷1,000)×5 = 8×5 = 40 lbs.
