Quick start
- Enter the paver area in square feet.
- Enter base depth and bedding sand depth in inches.
- Enter waste percent and a rough tons-per-cubic-yard value for the base material.
Best uses
These are the situations this tool is meant for. If your task is close to one of these, the examples and notes below can help you choose the right inputs.
- Estimate base gravel for a patio or walkway.
- Convert base volume into approximate tons.
- Estimate bedding sand volume separately.
- Add waste for compaction and uneven ground.
What this calculator is solving
The Paver Base Calculator estimates the material layers below a paver surface. It separates compacted gravel base from bedding sand so you can plan each material.
You do not need to memorize the formula first. Start by matching each input label on the calculator to the number, date, unit, or setting you actually have.
The formula in plain language
In plain language: The calculator multiplies paver area by base depth and bedding depth, adds waste, converts cubic feet to cubic yards, and estimates base tons from tons per cubic yard. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
If that sounds abstract, use the example cards on the calculator page. They show a complete set of inputs and the kind of answer you should expect.
How to read the answer
Read the headline result first. Then look at the smaller supporting lines because they explain the parts behind the answer, such as totals, units, ranges, or formula steps.
- Base cubic yards is the main volume to discuss with suppliers.
- Base tons converts the volume into approximate weight.
- Bedding sand shows the leveling layer volume separately.
Common mistakes to avoid
If the answer looks strange, the most likely cause is a small input mismatch: the wrong unit, date, weight, scale, mode, or policy assumption.
- Do not use loose depth if your design calls for compacted depth.
- Do not ignore drainage, soil, slope, freeze-thaw, and traffic load.
- Do not assume every gravel product has the same tons per cubic yard.

FAQ in plain language
When should I use the Paver Base Calculator?
Use it when your task matches one of these common needs: Estimate base gravel for a patio or walkway. Convert base volume into approximate tons. It works best when you already know the values, dates, units, or settings the page asks for.
What is the Paver Base Calculator doing with my inputs?
In plain language: The calculator multiplies paver area by base depth and bedding depth, adds waste, converts cubic feet to cubic yards, and estimates base tons from tons per cubic yard. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.
What do the main Paver Base Calculator inputs mean?
Base depth: the compacted gravel layer below the pavers. Bedding depth: the leveling sand layer directly under the pavers. Tons per cubic yard: a rough density for converting gravel volume to weight. Waste percent: extra material for compaction, uneven grade, edge loss, and small measurement differences.
How should I read the Paver Base Calculator answer?
Read the headline estimate first, then check the material, waste, coverage, and unit lines. For project tools, the supporting lines are often the difference between a rough idea and a list you can actually shop from.
What should I double-check before trusting the answer?
Real paver base design depends on soil, drainage, compaction, freeze-thaw, traffic load, slope, edging, and local installation practice. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.
Is paver base depth the loose depth or compacted depth?
Use the compacted depth you want to end with. Loose gravel can settle after compaction, so a real project may need more loose material than the compacted volume suggests.
