While laying tile, the most important item you’ll need is a tile trowel, which is also sometimes referred to as a notched trowel.
If you purchase the incorrect kind of notched trowel, you might not be able to finish the tiling job you started.
For instance, for a 4×4 tile, you should know What size trowel for 4×4 tile you need.
So, stick to this article to know the ideal size of a trowel for a 4×4 tile.
What Size Trowel For 4×4 Tile?
For installing 4×4 inch ceramic, porcelain, or stone wall tiles, use a 1/4″ x 3/8″ square-notched trowel to provides the right amount of mortar coverage under tiles. Larger tiles may require a 1/2″ square notch, while mosaics use a smaller 1/8″ V-notch trowel. Match trowel size to tile dimensions.

Different types of trowels
The shape of the tooth on a trowel, also called the notch, affects the amount of mortar applied and differentiates various types of trowels.
The notch allows for straight lines and leaves gaps between courses of material for air to escape.
Knowing the different types of notched trowels, such as square-notch, U-notch, and V-notch is important for proper tile installation.
Square-Notch Trowels
Yes, indeed in some instances, the mortar amount could be very crucial.
This trowel works on tiles measuring 4 or more 4 inches. So, you have the option to apply this sort of trowel for your 4×4 inches tiles.
As the floor tiles are more than 4 inches in general, the square-notches trowels have very wide use in laying those tiles.
As it will pass the highest amount of mortar, you will get flat spaces in between the mortar.
The rectangular or square notches may turn out to be a less preferable option as flat spaces are not preferred by all.
U-notch trowels
Now you don’t prefer the vast spreading of mortar between the lines, U-shaped trowels could be the one for you.
As you can guess already, it spread much less mortar than the square-shaped ones do.
Compared to the V-shaped trowels, it does spread more mortar. So, if you want to secure the middle ground for an ideal installation, you know what to do.
As the previous one discussed, this sort of trowel only works for tiles measuring 4 or more 4 inches.
V-Notch Trowel
A further introduction is much less important here as the name tells you the story here.
You get V-shaped edges with this sort of trowel. Around the edge, there is a sawtooth, or more specifically, a zig-zag pattern.
You cannot just use this at your whim. This type of trowel goes fine with tile up to 4 inches.
The mesh backing and the mosaic tiles get perfection with this trowel. For ceiling installation and wall application, this trowel does a perfect job.
You get to apply the mortar in a minimalistic manner. So, far safer than the square-notch trowels for the specific purposes mentioned above.
As you have 4×4 tiles, this trowel can just work fine. So, this could be one of your ideal options for installing the trowels.
Pick the right size trowel
Clear as daylight – for the larger tiles, measuring more than 4 inches, the square-shaped trowels are ideal.
They can still do the job for a trowel measuring 4 inches, 4×4, but not less than that. The same goes for the U-shaped trowels.
We opt for the V-notch if we get to work on the mosaic tiles.
The Mortar Coverage Matters The Most
But, things change a bit. The size is the second consideration when the mortar coverage matters the most.
What amount of mortar you prefer to leave under the tiles will tell you what shaped tile you need.
The ANSI standard
In this regard, the ANSI standard suggests that there is a minimum-required specification for the proper installation of ceramic tiles. What’s that?
- 80% mortar coverage is the least for Dry areas.
- 95% coverage is essential for wet areas, such as your showers or bathrooms in particular.
- While a 95% coverage is mandatory for the installation of natural stone tiles.
Industry-Standard Applies For Household
While discussing the ANSI standard, some people may argue that the standard is set for industrial applications.
But that is not the case actually, as proper installation is in question irrespective of the place.
So, stick to the standard for households, all sorts of trowel machines, tools used, and hand trowels.
Test the mortar coverage
Finally, to be sure that the mortar coverage is standard, check it yourself.
You just have to check the backface of the trowel by pulling it back from the installed mortar. Do this to a single tile, the rest will just be fine with expert hand installation.
If the backface doesn’t have the mortar evenly, the trowel you have is not ideal.
More specifically, look for if the trowel leaves 15% blank spots on the backface. If so, change the trowel.
For wet areas, the blank spots on the backface of the tile shall not be more than 5%.
