Floor Tile Calculator

How to calculate Floor Tile Calculator?

Calculate the room area in square feet and divide by the area of a single tile (in square feet) to get the number of tiles required.

Key formula: raw_tiles_needed = room_area_sq_ft / tile_area_sq_ft (where tile_area_sq_ft = (tile_length_in_inches × tile_width_in_inches) / 144).

Using the Floor Tile Calculator calculator: an example

Example values: room 12 ft × 10 ft, tile 12 in × 12 in.

Step-by-step calculation:

1. Compute room area: 12 ft × 10 ft = 120 sq ft.
2. Compute tile area: (12 in × 12 in) / 144 = 1.0 sq ft per tile.
3. Raw tiles needed: 120 ÷ 1.0 = 120 tiles.
4. Add 10% waste: 120 × 1.10 = 132 tiles; round up to whole tiles.

Frequently Asked Questions

Why divide by 144 when calculating tile area?

Tile dimensions are given in square inches; dividing by 144 converts square inches to square feet because 1 sq ft = 144 sq in.

Should I round up the tile count?

Yes. Always round up to the next whole tile and include waste to ensure you have enough material for cuts and breakage.

How much waste should I add?

A common recommendation is 10% waste for standard layouts. Increase the percentage for diagonal patterns or complex cuts.
