Measurement Tips

📏 Measuring Your Lawn

For rectangular areas, measure length and width. For irregular shapes, break them into smaller rectangles and circles, then add the areas together.

📐 Depth Guidelines

Mulch: 2-3 inches. Topsoil: 6-12 inches for new lawns. Compost: 1-2 inches mixed into top 6-8 inches of soil.

🌱 Seeding Rates

New lawns need 2-4x more seed than overseeding. Different grass types have different seeding rates - use our Grass Seed Calculator for accuracy.

⚖️ Unit Conversions

1 cubic yard = 27 cubic feet. Most bags are 2 or 3 cubic feet. Always check bag sizes when buying materials.

Common Questions

How accurate are these calculators?

Add 5-10% extra for most materials to account for waste, irregular shapes, and settling. For critical projects, err on the side of buying slightly more.

Troubleshooting

Calculator not working?

  • Make sure you've entered valid numbers in all required fields
  • Check that values are positive (greater than 0)
  • Try refreshing the page if results don't appear
  • Enable JavaScript if it's disabled in your browser

Results seem wrong?

  • Verify you're using the right tool for your project
  • Make sure depth is in inches, not feet
