## Definition

A grass seed calculator is a landscaping utility that estimates the weight of grass seed required to plant or overseed a specific lawn area. The calculator processes the total lawn area and the desired seeding method, differentiating between establishing a new lawn and overseeding an existing one. By applying standard agricultural seeding rates per square foot or square meter, it determines the total pounds or kilograms of seed needed. Homeowners and landscapers use this tool to purchase the correct quantity of seed.

## How to Use

1. **Enter the lawn area** — Type the total surface area of your lawn in square feet or square meters.
2. **Choose seeding project** — Select whether you are planting a new lawn or overseeding an established one.
3. **Read seed weight** — View the estimated weight of grass seed required in pounds or kilograms.
