What is Tile Calculator?

Estimates tile quantities, square footage coverage, and box packaging units for floor and wall tiling projects.

How to Use This Calculator

  1. Enter room length and width in feet.
  2. Select tile size.
  3. Keep 10% waste buffer.
  4. Read total tiles and boxes needed.

The Mathematical Formula & Variables

Net Area = Length * Width; Gross Area = Net Area * (1 + Waste / 100); Tiles = Gross Area / Tile Square Footage

Step-by-Step Worked Example

Scenario: 20 ft x 15 ft room tiled with 12"x12" tiles at 10% waste.

  1. Net area = 20 * 15 = 300 sq ft.
  2. Gross area = 300 * 1.10 = 330 sq ft.
  3. At 1.0 sq ft/tile: 330 tiles required (33 boxes of 10).

Result: 330 Tiles (33 Boxes)

Frequently Asked Questions

Why is a 10% to 15% waste factor standard for tile?

Cutting tiles around borders, drains, and corners produces offcut scraps that cannot be reused.
