What the sand base calculator solves
Use the sand base calculator for patio paver bases, leveling sand, and small masonry projects.
Formula
How to use it
- Enter length and width in feet.
- Enter depth or thickness in inches.
- Use the package yield or truckload yield to round up material.
How to read the answer
Thin layers still add up across patios because area is usually large.
Common mistakes and edge cases
- Compacted base depth and loose bag volume can differ.
- Do not use leveling sand to replace structural base.
- Slope and drainage may change depth.

Frequently asked questions
Why show both cubic feet and cubic yards?+
Bags often list cubic-foot yield, while bulk concrete, soil, mulch, and aggregate are commonly ordered in cubic yards.
Does this replace a contractor estimate?+
No. It is a planning calculator. Site conditions, compaction, forms, slopes, and local material packaging can change the order quantity.
