How wide should grout lines be?
Actual finished grout spaces will vary from 1/8″ to 1/4″ if 3/16″ spacers are used. If smaller spacers like 1/8″ are used, it will accentuate the size difference of handmade tile. Finished grout lines will vary from 1/16″ to 3/16″.

The consistency of grout should resemble smooth peanut butter. It should be malleable but not dripping from the trowel when lifted. If the mix is too stiff or dry powder is visible, add more water. If the mix is too fluid and watery, add more grout powder.
How thick is grout under tile?
Most tile installations require a 3/16-inch layer of mortar beneath the tile. A mortar layer 3/16 an inch thick is accomplished by spreading mortar with a 3/8-inch by 3/8-inch square-notched trowel. This thickness is ideal for most tile installations.
How much space do you need between tile and grout?
TCNA recommends a minimum 1/8″ grout joint for rectified tile and minimum 3/16″ grout joint for calibrated tile. They also suggest adding to this width the amount of edge warping on the longest edge. For example, if the edge warping of a rectified tile is 1/32″, the minimum grout joint is 1/8″ + 1/32″ = 5/32″.
Can grout lines be too big?
They have small protrusions called lugs that fit against adjoining tiles and create an automatic space for grout, normally 1/32 to 1/16 inch wide. Grout lines on walls usually do not exceed 1/16 inch because the tiles need to be stacked to help support them during installation.
