Example shown — replace it with your own lawn area and product application rate.
How it works
- Enter your lawn's total area.
- Enter the product's application rate per 1,000 square feet.
- See exactly how much product you need.
Calculation divides your lawn area by 1,000 and multiplies by the product's rate — the standard coverage math printed on fertilizer, seed, and weed control product labels.
FAQ
Is my lawn data uploaded anywhere?
No. The calculation happens entirely in your browser — nothing is sent to a server.
How is product amount calculated?
Your lawn area divided by 1,000, multiplied by the product's application rate per 1,000 square feet — the standard way fertilizer and lawn product labels express coverage.
Where do I find the application rate?
On the product's bag or label, usually listed as pounds (or ounces) per 1,000 square feet.
Does it account for irregular lawn shapes?
No — it works from a total square footage figure. Measure or estimate your lawn's area first (breaking an irregular shape into simpler rectangles helps).
