Calculate your quantity
Use your measured area and the actual product specification. The result updates as you change an input.

How this estimate works
Order area = measured square feet × (1 + cutting allowance ÷ 100); rolls = order area ÷ supplier roll coverage, rounded up.
Seed, sod, and fertilizer use different rates and buying units. Use the grass species, bag label, supplier coverage, and soil test appropriate to the site.
Before you order
- Measure the area to treat, not the whole property.
- Check the seed or fertilizer label and local guidance.
- Include preparation and establishment care in the project plan.
Planning estimates can differ from delivered or installed quantities.
Reference
Penn State Extension: Lawn establishment. Product specific rates and installation specifications take precedence over general defaults.
