Worktop and splashback calculator

Quick answer: Enter each straight run of worktop in centimetres. It adds up the worktop area and the splashback area so you can ask suppliers for accurate quotes. Always have the final sizes measured on site.

Enter each straight run of worktop in centimetres (up to five).

Run 1 length (cm)

Run 2 length (cm)

Run 3 length (cm)

Run 4 length (cm)

Run 5 length (cm)

Worktop depth (cm)

Splashback height (cm)

The splashback is worked out as the total run length times the height, so subtract any window or hob area your fitter says is not covered.

How to use the calculator

Measure each straight run along the wall in centimetres and enter it. Standard worktops are around 60 cm deep, but check yours. Suppliers and fitters will confirm exact sizes, joints and cut-outs for the hob and sink on a site visit, so use this for early budgeting. See kitchen worktops compared for the materials.

Frequently asked questions

How much extra tile should I order?

Ten percent extra is the usual allowance for cuts and breakages. More if you have a pattern or lots of corners.

Does it handle L-shaped or U-shaped kitchens?

Yes: enter each straight run separately. Corner overlaps are small, but your fitter will confirm the final sizes.
