FAQ

How do I calculate how many paving blocks I need?

Multiply the area by 10,000 to get square centimeters, divide by the block area in square centimeters, then add the waste percentage. The calculator does this automatically for you.

Why should I add waste?

Waste covers cuts, breakage and fitting losses. For most projects, 5% to 10% is common, but complex layouts may need more.

Does this calculator tell me how many packs or pallets to buy?

Yes. After calculating the required paving area, it divides the result by the coverage of one pack or pallet and rounds up.

Can I use it for a driveway, path or terrace?

Yes. It works for any rectangular or custom paving area as long as you know the total surface size and block dimensions.
