Tile Calculator and Cost Estimator

What Tile Calculator and Cost Estimator is for

Tile Calculator and Cost Estimator is the page to open when you need tile calculator and cost estimator from measurements you already have. It belongs with the other construction calculators because that is the work this arithmetic supports. The area in square feet is the area in square feet. Type the entries first. The result stays hidden until you press Calculate, so a half-finished form never flashes a number you might mistake for the answer.

The formula in plain language

Tile count is the room area divided by the area of one tile, with the grout joint added to both the width and the length of the tile. Round up to a whole tile. Boxes are the tile count divided by the number of tiles in a box, rounded up.

A worked example

A 10 foot by 12 foot floor is 120 square feet. A 12 inch tile with a 1/8 inch joint covers about 1.02 square feet, so the floor needs 118 tiles before cuts. Buy extra for the cuts along the walls.

Area is the measurement under paint, tile, flooring, and a price per foot. This tile calculator and cost estimator result should agree with paint coverage and carpet for the room.

Mistakes that move the answer

• A 12 inch tile with grout is slightly larger than one square foot. Ignoring the joint overbuys by a little, which is safer than underbuying.
• Diagonal layouts need more waste than a straight grid.

How to check the result

After Calculate shows the tile calculator and cost estimator result, redo the last operation with a pencil using the rounded figures on the screen. Matching that check means the inputs were read correctly. If you edit a label or a sentence in this HTML file, reload the page. The form and this article both live in the file, so the edit is what visitors will read.
