Kitchen Backsplash Tile Guide

A kitchen backsplash typically covers the wall between countertops and upper cabinets -- standard height is 18 inches, but full-height backsplashes (counter to ceiling) are increasingly popular. The tile area is calculated as linear feet of countertop x backsplash height, minus any windows.

Subway tile (3x6) is the most popular backsplash choice -- classic, affordable, and forgiving to install. Mosaic sheets (12x12 mounted on mesh) are even easier for DIY. Natural stone and large-format tiles look stunning but require more skill to cut around outlets and corners.

Frequently Asked Questions

Measure the total linear feet of counter that needs a backsplash, multiply by the height in feet, then subtract window areas. A typical kitchen with 25 linear feet of counter at 18 inches high: 25 x 1.5 = 37.5 sq ft. Add 15% for cuts around outlets, corners, and edges: about 43 sq ft total.

Peel-and-stick mosaic sheets are the easiest (no mortar, no grout) but are not suitable for behind stoves or anywhere that gets wet. For a real tile backsplash, pre-mounted mosaic sheets (on mesh backing) are easiest -- apply thinset, press the sheet on, grout. Subway tile is the next easiest because the simple pattern requires fewer precision cuts.
