Lawn Seed & Fertilizer Coverage Calculator

How to calculate lawn coverage?

Lawn coverage is calculated by dividing your total area by the standard coverage unit (usually 1,000 sq ft) and multiplying by the product rate.

Formula: Total = (Lawn Area / Coverage Unit) × Rate

Using the coverage calculator: an example

Example: A 5,000 sq ft lawn using a fertilizer with a 3 lbs/1,000 sq ft rate and 15 lb bags.

Step-by-step calculation:

1. Divide area by 1,000 (5,000 / 1,000 = 5 units)
2. Multiply by rate (5 units × 3 lbs = 15 lbs total)
3. Divide by bag weight (15 lbs / 15 lb bag = 1 bag)

Frequently Asked Questions

How do I measure my lawn area?

Divide your yard into basic shapes like rectangles and triangles, calculate their individual areas, and sum them up.

Is it better to have too much or too little?

Always aim for the exact amount; over-fertilizing can burn grass, while under-seeding leads to patchy growth.

Does soil type affect coverage?

While soil doesn't change the area, poor soil may require a higher seeding rate for successful germination.
