Pavers base and bedding sand
Estimate paver pieces or packs plus base and bedding volumes using net area, supplied depths and an explicit loose-base allowance.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
pavers = ceil(area × allowance / supplied coverage); base volume = installed area × compacted depth × supplied loose-volume factor
Quantity and supplied-cost arithmetic only. Verify measurements, product coverage and purchasing units. Prefilled values and allowances are illustrative, not recommended specifications. No structural sizing, code approval, installation design or optimized cutting layout is supplied. Optional zero prices are omitted; unknown costs are not assumed free. Product coverage must match shape and joint module. Piece and full-pallet options are alternatives; unused pallet stock is not laid or included in base area. Use designed base and bedding depths; loose/compacted conversion is supplied, not a prescribed compaction factor. Borders, pattern cuts, polymeric joint sand, drainage, excavation, load capacity and labor are excluded.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Area entry method: Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Measured area before separate deductions (ft²): Enter square area, not a length. Use the stated installed, net or package coverage basis; openings are deducted only once. Used with: I know the measured area.
- Rectangular wall, ceiling or ground surfaces: Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value. Used with: Measure rectangular surfaces.
- Surface name: Use matching records or an explicitly identified assumption for surface name. Unknown is not the same as zero.
- Surface length (ft): Measure this dimension and select feet, inches or meters. Use actual product dimensions rather than a nominal trade size unless this field explicitly asks for nominal module coverage.
- Surface width or height (ft): Measure this dimension and select feet, inches or meters. Use actual product dimensions rather than a nominal trade size unless this field explicitly asks for nominal module coverage.
- Openings or excluded area to deduct once (ft²): Enter square area, not a length. Use the stated installed, net or package coverage basis; openings are deducted only once.
- Your extra material allowance (%): Extra material above the net measured requirement. Supply an allowance appropriate to your cuts, handling and product; the example is not an industry recommendation.
- Paver purchasing basis: Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Effective coverage per paver including its joint module (ft²): Enter square area, not a length. Use the stated installed, net or package coverage basis; openings are deducted only once. Used with: Individual pavers.
- Pieces per full pack or pallet (pieces/pack): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value. Used with: Individual pavers.
- Coverage per full pack or pallet (ft²): Enter square area, not a length. Use the stated installed, net or package coverage basis; openings are deducted only once. Used with: Packs or pallets by stated coverage.
- Specified compacted base depth (ft): Measure this dimension and select feet, inches or meters. Use actual product dimensions rather than a nominal trade size unless this field explicitly asks for nominal module coverage.
- Your loose-base volume increase over compacted volume (%): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Specified bedding sand depth (ft): Measure this dimension and select feet, inches or meters. Use actual product dimensions rather than a nominal trade size unless this field explicitly asks for nominal module coverage.
- Your extra bedding sand allowance (%): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Optional price per paver or coverage pack as selected (selected currency): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Optional base material price per loose cubic yard (selected currency): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
- Optional sand price per cubic yard (selected currency): Use a measured quantity, product label, supplier quote or explicit assumption on the stated basis. Zero is intentional exclusion, not an unknown value.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.

Use the result well
Compare net installed quantities with allowances and whole purchased units. Review product instructions and missing materials before ordering.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
