Paving Stone Calculator
Calculate how many paving stones you need for a patio or driveway, including joints, waste and bedding material.
Choose your paving stone format, the joint width and the area – this calculator determines how many stones you need and the bedding material (gravel/sand) for the base.
Pro tips
- For driveways (vehicle traffic), use stones at least 6 cm thick and a properly compacted base.
- Edging/border stones are not included here – plan those separately.
Frequently Asked Questions
How many paving stones do I need per square meter?
It depends on the stone format and joint width – for 20×10 cm stones with a 3 mm joint, that's about 47 stones per m². The calculator above works this out for your format.
How thick should the bedding under paving stones be?
For walkways, 3-5 cm of gravel bedding is usually enough; for driveways with vehicle traffic, 5-8 cm on a compacted base is better.
What joint width is typical for paving stones?
Usually 3-5 mm for concrete pavers, wider for natural stone or a more rustic look, depending on the desired appearance.
Does the base need to be compacted?
Yes, definitely – an insufficiently compacted base leads to sinking and uneven paving over time.
