Tile counts are simple in a rectangle, but cuts, pattern repeats, and future repairs change the order. This guide explains a simple way to prepare your measurements before using the calculator.
Start with a clear sketch
Write down the shape, the units, and any openings or sections that change the measurement. A quick sketch makes it easier to catch a missed corner and gives you something useful to compare with a supplier quote.
- 1.Calculate square footage first.
- 2.Use a larger allowance for small rooms and complex patterns.
- 3.Confirm box coverage before checkout.
Keep the result realistic
Coverage numbers are averages. Texture, pattern, moisture, cuts, and the skill of the installer can all change the final amount. Treat the result as a first pass, then check the manufacturer's coverage, local rules, and the conditions at the project site.

Should I round up?
Usually, yes. A small allowance helps with uneven surfaces, cuts, and product packaging. Confirm the final quantity with the product label or a local supplier.
Are these exact construction quantities?
No. They are planning estimates based on the measurements you enter. Project conditions and local building requirements can change the final order.
