Paver Calculator
The Paver Calculator estimates the count of rectangular pavers needed to cover a surface, including an adjustable allowance for breakage and cuts. It is helpful for a first material estimate for patios, paths, and similar layouts.
How to use this calculator
- Enter the area to cover, paver length and width in centimetres, and a waste allowance percentage.
- Review the worked patio pavers and compare its arithmetic with the inputs you plan to use.
- Change one input at a time when exploring a different scenario, and keep units and assumptions consistent.
Paver quantity
Pavers before waste = surface area ÷ (paver length × paver width converted to square metres); apply waste and round up.
- This estimate treats pavers as a simple rectangular coverage unit. Joint width, borders, pattern, edge cutting, and product pack size can change the actual purchase quantity.
- The page's numerical output is calculated from the values entered; it does not independently verify whether those inputs fit the real-world situation.
Worked examples
Patio pavers
A 12 m² patio uses pavers measuring 20 cm by 10 cm with 10% waste.
Each paver covers 0.02 m²; 12 ÷ 0.02 = 600; with waste = 660
Estimate 660 pavers including the 10% allowance.
Understanding the result
The count is inversely related to the area of each paver; larger pavers require fewer units.
Irregular boundaries, herringbone patterns, and cuts around drains can need more material than area alone suggests.
Important notes
Check the manufacturer's coverage and supplier pack count, and allow for future repairs where appropriate.
Displayed values may be rounded for readability. Keep appropriate precision for intermediate calculations and check the unit labels before using the result.
