Backsplash tile box estimator

Backsplash Tile Calculator

Backsplash tile formula

Net backsplash area = counter run x backsplash height - openings

Order area = net area x (1 + waste %)

Tiles = order area / tile face area

Boxes = order area / box coverage

Sample takeoff

A 12 ft counter run with an 18 in backsplash, 3x12 in tile, 10 ft² box coverage, and 10% waste needs about 2 boxes and 80 tiles.A 3.6 m counter run with a 450 mm backsplash, 75x300 mm tile, 0.93 m² box coverage, and 10% waste needs about 2 boxes and 80 tiles.
