Flooring calculator
Enter your room size, pick how you plan to lay the boards, and get the square metres and whole packs to buy, with a waste allowance that matches your pattern instead of a one-size-fits-all 10%. It’s free and instant, with no signup.
This is the estimate. The designer lays out every board in your actual room, so the pack count comes from real cuts, not a flat percentage.
See the actual layout freeHow the calculation works
Flooring is bought in three steps: measure the floor area in m², add waste for the cuts your laying pattern forces, and convert to packs by dividing by the coverage printed on the pack and rounding up. The waste step is where estimates go wrong, because a herringbone floor cuts every board at the walls at an angle and wastes two to three times what a straight lay does. The pattern selector above applies the right range for you.
For an exact answer instead of an estimate, the floor designer draws your actual room and lays every board in it. It counts the real offcuts, keeps the wall pieces above sliver width, and produces a board-by-board cut list.

Frequently asked questions
- How do I calculate how much flooring I need?
- Multiply the room length by the width in metres to get the area, add a waste allowance for your laying pattern (5% to 8% for a straight lay, up to 20% for herringbone), then divide by the coverage printed on the pack and round up to whole packs.
- What waste percentage should I use?
- It depends on the laying pattern and room shape: 5% to 8% for a straight lay in a simple rectangle, 8% to 12% with alcoves or angled walls, 10% to 15% for a diagonal lay, and 15% to 20% for herringbone or chevron.
- Is this calculator free?
- Yes, and it runs on this page with no signup. The floor designer it links to is also free to try, and your first project includes the full layout and cut list.
- How is this different from laying out the boards?
- A percentage is only an estimate, while a layout is an actual count. The designer places every board in your real room shape, so it knows which offcuts are reusable and how many packs the floor really needs, which is usually fewer than a padded percentage suggests.
