You can calculate how much tile you need in just a few easy steps. The first step is to know how large of an area you want to cover. Begin by measuring the room or wall lengths and widths in feet, then multiply these measurements together to get the area in square feet.

To help determine the amount of tile for your needs, below is an easy to use tool for calculating the square footage of an area. To start, please provide the area measurements. When measuring for floor tile the rule is: Length x Width + Waste = Amount Needed

I can therefore calculate the total tiling area of the shower wall in square footage: $$Area = Area,Length × Area,Width = 10,ft × 15,ft = 150,ft^2$$ and the individual tile area in square inches: $$Tile,Area = Tile,Length × Tile,Width = 8,in × 5,in = 40,in^2$$

The square footage of a room is determined by multiplying its length by its width. For example, a room that measures 12 feet by 10 feet has a total area of 120 square feet. When it comes to tiles, their size is typically given in square inches.
