Paver Calculator
This paver calculator shows how many pavers your area needs: enter length and width, paver size, joint and waste, then read the count and the amount for bedding and base layers.

How it is calculated
For 20 m² (215 sq ft) and pavers of 20 × 10 cm (8 × 4 in) with a 3 mm joint you need about 957 pavers, around 1,005 with 5 % waste. The calculator counts the area of each paver including its joint and divides the total area by it.
How it is calculated
A paver of 20 × 10 cm with a 3 mm joint occupies 20.3 × 10.3 cm, which is 0.0209 m². That fits about 47.8 pavers on one square meter. The number is multiplied by the area and rounded up. A surcharge for waste and spares is added, which you can adjust. For the build-up the tool multiplies area by thickness and gives the volume of bedding (grit, sand) and base layer in cubic meters.
Planning tips
- Measure the area in rectangles and add partial areas when the shape is irregular.
- Order all pavers at once: batches can differ slightly in color.
- Allow more waste for curves and diagonal patterns.

Frequently asked questions
How many pavers do I need per square foot?
Divide the area by the area of one paver including joint. For 8 × 4 in pavers with a 1/8 in joint that is about 4.3 pavers per square foot.
How much waste should I add?
A simple bond often needs only a few percent; diagonal layouts, curves and many cuts need more. The value is adjustable in the calculator.
How thick are bedding and base?
Bedding is usually a few centimeters thick, the base much more. The exact values depend on ground and load and can be set in the calculator.
Do I need to include the joint?
Yes, the joint is part of the area covered per paver. If you forget it you order too many pavers.
