How Many Tiles for a 10x12 Kitchen Floor? (2026 Guide)

Tile count for a 10x12 kitchen floor

A 10x12 ft room measures 10 x 12 = 120 sq ft. That is the area you cover when the kitchen is empty. Divide it by the area of one tile to get the net count, then add about 10% for cuts and breakage to get the buy count:

These counts assume the whole 120 sq ft gets tiled. Kitchens are different: the net laid area is what remains after you subtract the footprint of the cabinets and island, and the net area is what the count is really based on. A typical L-shaped kitchen covers roughly 90-100 sq ft of exposed floor, so if your net comes to 100 sq ft, a 12x12 floor takes 100 net tiles and you'd buy 110. Scale any row above the same way: net tiles = net sq ft ÷ per-tile sq ft.

Worked example: 12x12 tiles on a 120 sq ft floor

Take the full 10x12 ft space with 12x12 in tile, the kitchen standard. Each tile covers exactly 1.0 sq ft, so the layout math is one tile per square foot:

• 120 sq ft ÷ 1.0 sq ft per tile = 120 whole tiles across the field of the room.
• Add cuts: every wall edge, the door threshold, and the strips of tile that show along the cabinet toe kicks break a full tile, so add about 12 more (10%).
• Buy 132 tiles — usually 11 boxes of 12 per box. Keep the unopened boxes; tile stores take back full boxes on most orders.

Cabinets complicate a naive count only because you stop the tile at their edge rather than under them. What looks like an extra wall is really 4-8 linear feet of toe kick, which is why pros plan the field, snap chalk lines from the most visible wall, and cut the back rows to fit — never the front ones. Before ordering, subtract cabinet and island footprints and run the number through the tile calculator so your buy count matches the net floor.

Three tips that change the count

• Measure the net, not the room. For an occupied kitchen, add the boxed-in area of each cabinet run and the island, subtract it from 120 sq ft, and recompute. Ignoring 20-30 sq ft of cabinetry buys you a full box of waste you'll never install.
• Pick a floor-rated glaze. Kitchen floors get spills, grease and dropped pans — choose a glazed porcelain or ceramic tile rated for floor use, and a textured finish if the floor meets a sink or entry area. Wall tile on a kitchen floor chips and gets slick.
• Budget for grout joints of 1/8-3/8 in. The joint is part of the layout: rectified tile goes tight at 1/8 in, while unrectified tile needs closer to 3/8 in, and wider joints eat slightly into the per-tile coverage on long runs.

Compare with other room sizes

Tile math is the same everywhere — only the area changes. See how many tiles a whole room needs for the general method, how many tiles per square foot for the unit math, or the tighter bathroom version at how many tiles for a 5x7 bathroom floor.
