## How do I calculate how much grout I need?

To work out how much grout you’ll need, follow this easy 6-step calculation:

1. Step 1: Tile width (mm) + tile height (mm) = A.
2. Step 2: Size of spacers (mm) x tile thickness (mm) = B.
3. Step 3: A x B x 1.2 (this number is the coverage ratio of all UltraTile grouts) = C.
4. Step 4: Tile width (mm) x tile height (mm) = D.

## How do you calculate mosaic tiles?

Multiply the width and height to find the total area in inches, then divide by 144 to find the amount of square feet needed (amount of inches in a square foot).

## Do I want sanded or unsanded grout?

Sanded grout is best for grout lines ranging from 1/8-inch to 1/2-inch. Grout lines wider than 1/2-inch are impractical and will crack and become unstable. Because unsanded grout can also be used for 1/8-inch lines, between the two it is recommended that you use sanded grout.
