Use case

Patio planner

Most patios are a rectangle against the house, sometimes with a corner cut off or a step out for a seating area. This planner starts with a 20 × 20 cm square paver in stack bond and the Pedestrian load class.

Start with the shape

Enter width and length to create a rectangle, then drag corners or add points for steps and angles. If the patio joins a path, add the path as a second surface on the same drawing.

Choosing paver and pattern

Square pavers work in stack bond, running bond or on the diagonal. Stack bond is the calmest look and keeps the cuts straight. Rectangular pavers add herringbone and basket weave, and the mixed format adds Roman bond and Opus Romano. The stone colour preview helps you match the house before you order. For ready-made layouts with quantities per m², see the paver pattern templates.

What the shopping list covers

The list separates full stones from stones that need cutting. It adds crushed stone and grit for the base, curbstones and mortar for the perimeter, joint filler options from quartz sand to epoxy mortar, and the excavation depth. Print it or save it as a PDF for the supplier.

FAQ

Do I need an account?

No. The planner runs in your browser, and saved projects stay on your device.

Can I plan in feet and inches?

Yes. Switch the measurement unit to inches or feet and enter your measurements as you took them.

Key figures for this scenario

The figures come from the same formulas the planner uses. They leave out joints and waste; the planner's shopping list adds both for your surface shape.

Example: a 20 m² surface

For 20 m² you need about 500 pavers, 4.8 m³ of crushed stone (about 8.16 t, including a 20% compaction reserve) and 0.8 m³ of grit (about 1.2 t). Dig about 30 cm deep: 20 cm of base, 4 cm of bedding and 6 cm of paver.
