How to use this calculator
Enter the project surface dimensions and actual paver face size to estimate a whole-paver purchase count. Optional base and bedding depths provide geometric material volumes without applying the paver waste allowance.
- Measure the rectangular patio, walkway, or similar pedestrian area.
- Enter the paver face length and width using the dimension shown for the product.
- Adjust the paver-only extra allowance for cuts, breakage, and layout.
- Optionally enter the compacted base and bedding depths specified for the project or system; leave either blank to omit its volume.
Formula and methodology
Project area = length × width. Calculated face-area count = project area ÷ paver face area. Estimated paver purchase quantity = calculated count × (1 + selected extra percentage ÷ 100), rounded up. Gravel or sand volume = project area × entered depth; cubic yards = cubic feet ÷ 27.
Important: This calculator estimates material quantities for patios, walkways, and similar pedestrian areas. It is not structural, drainage, soil-bearing, freeze-depth, driveway, or engineering guidance.
How accurate is this estimate?
Project area, paver face area, and geometric material volumes come from the dimensions entered. Actual needs may vary because of cuts, patterns, joint spacing, edges, compaction, soil conditions, installation method, and manufacturer requirements.
Worked example
A 20 ft × 10 ft project covers 200 sq ft. With 12 in × 12 in pavers, the calculated face-area count is 200 pavers and 10% selected extra gives an estimated purchase quantity of 220 pavers. If the project inputs are 4 in of base gravel and 1 in of bedding sand, their calculated volumes are about 66.67 cu ft (2.47 cu yd) and 16.67 cu ft (0.62 cu yd), respectively.
Before you buy
- Cuts, patterns, joints, breakage, and edge conditions can change the paver quantity.
- Base and bedding depths vary with the installation system, climate, soil, use, and manufacturer requirements.
- Confirm depths and installation details with the paver manufacturer or a qualified installer.
- Use the Gravel Calculator for a separate aggregate area or the Concrete Calculator when comparing a rectangular slab volume.
Frequently asked questions
Does the paver extra percentage apply to gravel or sand?
No. It applies only to the estimated paver purchase quantity. Gravel and bedding sand use project area multiplied by the entered depth.
Why are base and bedding depths optional?
Installation requirements vary by project use, soil, drainage, climate, product, and system. Enter the applicable project values when known; manufacturer instructions or a qualified installer should control.
Does paver size include joint spacing?
The calculator uses the entered paver face area and does not add a joint-width correction. Patterns, joints, cuts, and edge conditions can affect the actual quantity.
