One of the most crucial aspects of tile installation is choosing the right trowel size. Various factors such as the shapes and sizes of the trowels, the types of notches, and the tile size and placement should be considered.
-
Tile placement significantly affects the trowel size selection. For instance, if you're laying tiles on the floor, the mortar bed needs to be thicker to withstand foot traffic. Likewise, if the surface you're laying tiles on slopes a bit, you would need to back-butter or spread out your mud-bed slightly thicker.

How do I know what size trowel to use for tile?
Here is a standard Guideline to help you make the right choice for a trowel based on tile size:- 3/16″ to 1/4″ V-notch: Mosaics tiles up to 4-1/2″ glazed wall tile.
- 1/4″ x 1/4″ U or Square notch: 4″ to 8″ tile.
- 1/4″ x 3/8″ U or Square notch: 8″ to 16″ tiles.
- 1/2″ x 1/2″ U or Square notch: 16″ and larger.
There are three primary types of notches - V-shape, U-shape, and square-notch. V-shape spreads less thinset than the same-sized square-notch, while the U-notch spreads out more than the v-notch but less than the square-notch. The major difference is how the thinset lies, affecting tile adhesion.
Choosing the right trowel size is crucial for successful tile installation. The trowel size should match the tile size, and the type of notch you use will affect the concentration level of thinset. Also, consider the placement of the tiles and the surface you'll be laying them on to determine the appropriate trowel size.
