Floor Tile Calculator
Work out how many floor tiles to order for a room of any size, with grout and waste included.
Tile math runs on your device — nothing is uploaded or storedTry: Room area=200, Area unit=sqft, Tile width=12, Tile height=12, Grout width=0.125, Waste=10, Tiles per box=10, Adhesive (lb/ft²)=0, Bag covers (ft²)=50 → 200.00 ft², 12 × 12 in, 196, 10%, 216, 22 (10/box), 13 lb
How to use
Floors are usually tiled with 12×12 in or 12×24 in tiles. Enter your floor area and the tile size — the calculator expands each tile by the grout width and adds your waste margin.
FAQ
What waste percent is normal for floors?
About 10% for a simple rectangular floor; add more for diagonal layouts or lots of cuts around doorways.
Should I buy extra tiles?
Yes — keep a few spare boxes in case a tile cracks later, since dye lots can differ between batches.
