Grass Seed Calculator
Planning to plant or renovate your lawn? One of the most important steps is figuring out exactly how much grass seed you need. Using too little can result in patchy, uneven grass, while using too much wastes money and seed.
Our Grass Seed Calculator simplifies this task by helping you quickly determine the precise amount of grass seed required based on your lawn size and grass type. It also estimates the total cost and how many 50-pound bags you’ll need, so you can budget effectively.
Why Accurate Grass Seed Calculation Matters
Grass seed coverage depends on the type of grass and the lawn area. Different grass types require different seeding rates, typically measured in pounds per 1,000 square feet. For example:
- Bermuda Grass needs about 5 lbs per 1,000 sq ft
- Kentucky Bluegrass requires roughly 8 lbs per 1,000 sq ft
- Tall Fescue calls for about 10 lbs per 1,000 sq ft
Choosing the right amount ensures:
- Healthy, thick, and uniform lawn growth
- Optimal use of your budget and resources
- Reduced need for reseeding or patch fixes later
How to Use the Grass Seed Calculator
- Measure Your Lawn
Enter the length and width of your lawn in feet. If your lawn isn’t a perfect rectangle, try breaking it into smaller sections, calculate each area, then add them up. - Select Grass Type
Choose the grass seed type that matches what you plan to plant. Each type has a recommended seed rate per 1,000 square feet. - Enter Seed Price
Input the price per pound of your grass seed. This helps estimate your total expense. - Calculate
Click the "Calculate" button. The tool will display:- Your lawn’s total area in square feet
- How many pounds of seed you need
- The estimated total cost of seed
- How many 50-pound bags you will need to buy
- Reset
Use the reset button to clear inputs and start fresh if needed.
Example Calculation
Suppose your lawn measures 60 feet long and 40 feet wide, and you want to plant Kentucky Bluegrass, which requires 8 pounds of seed per 1,000 sq ft. The seed price is $5 per pound.
- Lawn area: 60 × 40 = 2400 sq ft
- Seed required: (2400 / 1000) × 8 = 19.2 lbs
- Total cost: 19.2 × $5 = $96
- Bags needed: 19.2 / 50 = 0.384 → round up to 1 bag
This calculation tells you to purchase one 50-pound bag costing about $96 to seed your lawn properly.
