About this calculator

A kitchen backsplash covers the wall strip between the countertop and the upper cabinets, and its area is simply backsplash length × backsplash height, converted to square feet. Because tile must be cut around outlets, corners and the stove, this calculator adds a standard 10% waste allowance on top of the raw area.

Buying tile by exact square footage almost always leaves a homeowner short once cuts and breakage are accounted for, and over-ordering wastes money on materials that can't be returned once opened. Contractors and DIY renovators use this figure to order the right box count in one trip.
