Guide

How to use the Tile Calculator

1Enter the 'Room Length' and 'Width' in feet.
2Enter your 'Tile Length' and 'Width' in inches (e.g., 12x12 or 12x24).
3Set a 'Waste Allowance' (10-15% is standard).
4Click Recalculate to see the Total Tiles Needed and the breakdown of net area vs. waste.

Applications

Common Use Cases

Bathroom Floor: Calculate 12x12 or 12x24 tiles for a remodel.

Kitchen Backsplash: Estimate subway tiles (3x6) for walls.

Shower Walls: Determine material needs for a walk-in shower.

Patios: Plan paver or slate quantities.

The Maths Behind the Calculation

Tiles = (RoomArea / TileArea) * (1 + Waste%)

We calculate the square footage of the room and the square footage of a single tile. We then divide the room area by the tile area and add the specified percentage for waste (cuts/breakage).

Knowledge Base

Frequently Asked Questions

How much waste should I calculate for tile?

10% is standard for simple straight layouts. For diagonal patterns or rooms with many obstacles/corners, calculate 15-20% waste.

Does this include grout width?

No, this calculation assumes tight fits. Grout lines slightly reduce the number of tiles needed, but it is safer to ignore them to ensure you have enough extra tiles.

How do I measure a non-rectangular room?

Divide the room into smaller rectangles, calculate the area for each, and add them together. Enter the total square footage as an equivalent Rectangle (e.g. if 100 sq ft, enter 10x10).
