How Much Tile for a Kitchen Floor?
A 200 square foot kitchen: 15 boxes of 12x24 tile. The island and cabinets change the number.
A 200 square foot kitchen floor needs 15 boxes of 12×24 tile, 3 bags of thinset and 3 bags of grout at 15 % waste and 8 tiles per box. The figure moves a lot with your layout — a diagonal or herringbone floor needs noticeably more.
Estimates only. Textured walls, high ceilings, sprayers and major colour changes can all increase the amount you need. Always buy slightly more than the calculation suggests.
Tile needed by kitchen floor size
| Area | Surface | Tile size | Tiles | Boxes | Tile cost |
|---|---|---|---|---|---|
| Small kitchen, 80 sq ft, 12x12 | 80 sq ft | 12" × 12" | 88 | 9 boxes | $405 |
| Standard kitchen, 150 sq ft, 12x24 | 150 sq ft | 12" × 24" | 87 | 11 boxes | $495 |
| Large kitchen, 200 sq ft, 12x24 | 200 sq ft | 12" × 24" | 115 | 15 boxes | $675 |
| Large kitchen, 200 sq ft, straight lay | 200 sq ft | 12" × 24" | 110 | 14 boxes | $630 |
| Large kitchen, 200 sq ft, 24x24 | 200 sq ft | 24" × 24" | 58 | 15 boxes | $675 |
| Large kitchen, 200 sq ft, herringbone 12x24 | 200 sq ft | 12" × 24" | 120 | 15 boxes | $675 |
15 % waste for a diagonal or offset layout, 10 % for a straight grid. Assumes the whole floor is tiled, including under appliances.
What to include and what to skip
A kitchen floor is the easiest floor to measure because it is usually one open rectangle plus a pantry or utility corner.
- Include under the appliances. Tile under the dishwasher, oven and fridge. If you do not, you can never replace an appliance with a different size, and the gap shows.
- Include under the cabinets if they are going in after the floor, which is the normal order. If the cabinets are already fitted, measure to the toe kick instead — but then buy spare tile, because a future cabinet change will expose bare floor.
- Add the doorways. The strip under each door, and the transition to the next room, is easy to forget.
Why kitchens need more waste than bedrooms
Three reasons a kitchen floor eats more tile than the same area elsewhere:
- More complex shape. Cabinets, islands and appliance bays create inside corners everywhere, and each one generates offcuts.
- Tiling around an island means cutting on four sides instead of two.
- Large-format tile in a broken-up space wastes a lot. A 24×24 tile cannot be laid around an island without significant cutting.
If you are tiling around an island or a peninsula, use 20 % waste rather than 15 %.
Check the subfloor before you buy tile
Tile floors crack because the subfloor flexes, not because the tile was cheap. Before buying anything, check the deflection.
The standard test is the L/360 deflection limit: the floor must not bend more than its span divided by 360 under load. For a typical kitchen that means a stiff subfloor — usually plywood over closely spaced joists, plus a cement backer board or an uncoupling membrane.
If your floor bounces when you walk on it, no tile will survive. Fix the structure first. This is the single most common reason a kitchen tiling job fails.
Frequently asked questions
How much tile do I need for a 200 sq ft kitchen?
Fifteen boxes of 12x24 tile at 8 tiles per box with 15 % waste, plus 3 bags of adhesive and 3 bags of grout.
Should I tile under the kitchen cabinets?
Yes, if the cabinets are being fitted after the floor. It also lets you change the layout later. If cabinets are already in, measure to the toe kick and keep spare tiles.
What waste allowance for a kitchen floor?
10 % for a simple straight lay, 15 % for a diagonal or offset pattern, and 20 % if you are tiling around an island or peninsula.
Why does my kitchen floor tile crack?
Almost always because the subfloor flexes. Tile needs a floor stiff enough to meet the L/360 deflection limit. If the floor bounces, fix the structure before tiling.
