Sand calculator FAQ
How do I calculate how much sand I need?
Multiply your area in square feet by the depth in feet for cubic feet, then divide by 27. A 200 sq ft patio at 2 inches deep needs about 1.23 cubic yards.
How many tons are in a cubic yard of sand?
Roughly 1.3 tons, though it varies with sand type and moisture — the value this sand calculator uses. Confirm the exact conversion with your supplier when ordering.
How deep should sand be under pavers?
One inch of bedding sand over a compacted base is typical for paver patios and walkways — you screed it level before laying the pavers.
Should I order extra sand?
Ordering 5–10% extra covers settling and uneven spots — sand compacts noticeably after it is laid and wetted.
Does the type of sand change the amount?
The volume math is the same for every sand type, but weight per yard differs — check the tons conversion with your supplier when ordering by weight.
