Grass Seed Coverage Calculator
Calculate pounds of grass seed needed based on lawn area, seed type, and seeding method
About this calculator
The Grass Seed Coverage Calculator helps homeowners and landscapers determine the exact amount of grass seed needed for their lawn project. By inputting your lawn area, selecting your grass seed type, and choosing your seeding method (overseeding or new lawn), this tool calculates the precise pounds of seed required. This prevents waste from buying too much seed or poor coverage from purchasing too little, ensuring optimal lawn establishment and cost-effective seeding projects.
How to use
Enter your lawn area in square feet, select your grass seed type from the dropdown menu, and choose whether you're overseeding an existing lawn or planting a new lawn. The calculator will instantly display the recommended pounds of grass seed needed for proper coverage and successful germination.
Frequently asked questions
How much grass seed do I need per square foot?
Typically 2-8 pounds per 1,000 square feet, depending on grass type and whether you're overseeding or establishing new lawn.
What's the difference between overseeding and new lawn seeding rates?
New lawns require 2-3 times more seed than overseeding since you're establishing complete coverage rather than filling gaps.
Does grass seed type affect coverage rates?
Yes, fine seeds like bentgrass need less per square foot, while larger seeds like tall fescue require higher application rates.
