Outlet boxes to cut around3

A backsplash is a short, wide strip with plenty of cuts. Enter the run, height and any range gap you are leaving open.

How it works

Run length minus the range gap, × height, in square feet. Adds 10% for cuts around outlets and edges.

Before you order

  • Plan where the full tile lands at outlets and window edges before you start.
  • Turn the power off and use box extenders when tile thickness moves outlet faces.
  • Run tile a little behind the range only if the gap will show.

Common questions

How high should a backsplash be?

The usual space between counter and upper cabinets is 18 in. Many people run tile to the ceiling on open walls.

Do I subtract outlets?

No. They are small, and cuts around them often waste more tile than the hole saves.
