About Backyard Patio Ideas & Yard Calc

Backyard Patio Ideas & Yard Calc was built for one reason: too many weekend projects stall with a second trip to the home center — or end with a garage full of leftover bags.

Our calculators use the same formulas contractors use, expressed in US units (feet, inches, cubic yards, gallons and pounds) and matched to the bag sizes sold at major American retailers.

What we cover

• Epoxy resin for table tops, river tables and garage floors
• Mulch, gravel, river rock and topsoil
• Paver patios, base gravel and polymeric sand
• Concrete slabs, sidewalks, footings and post holes

Every calculator is free. We are supported by advertising and Amazon affiliate commissions, which never change the results you see.
