Regarding most institutions or activities, there are rules and regulations to follow, and tile installation is no exception. In most cases, the grout line sizes are determined by interior design considerations rather than requirements.

The well-known rule for all floor tiles is that they need at least 1/8 inch of grout lines or even thicker. Tile installation is a difficult task, but we’ve got your back. We’re here to give you the support you need to figure out what size grout line you should use tiles that are 6×24 in size.

In the case of 6 by 24 tiles, 1/8″ of grout line is best sufficient to fill the gap between the tiles. The surface you install them on, whether wall or floor, will have a refined and attractive appearance, making it look well-furnished and sleek with a good sense of connection.

Grout lines that can be used for 6 by 24 tiles range from 1/16″ to 3/16″ thick. We will look at the variety of options you can choose from when it comes to 6×24 tile grout lines and what size tile spacers you need for 6×24 tiles.


Grout lines that are 3/16 inches are best recommended for ceramic tiles. The gaps are large enough to leave any space for size variations and can even accommodate unpleasant edges found when it comes to handmade tiles. When using non-rectified tiles, you may experience difficulty in evening the tiles out and experience lippage.


The space 3/8 inch provides is usually made for thin glazed bricks that are industry standard. During the construction and tile installation process, the grout space you will use should be well thought out beforehand. Planning it out aids you in understanding the proper coverage space needed to complete one project. When unsanded grout is used, the lines may slump and crack.


For rectified tiles with a precisely cut, sharp edge, a 1/8″ grout line is used. The clear-cut margins of the slab, rectified sides enable the use of relatively small grout lines. There is less space across each tile component, making the interiors look neater. This cannot, however, be used for handcrafted tiles. If you use a 1/8″, you will get a tightened appearance and let the designs on the tiles look like they are gliding perfectly from one tile to the next.


For the tiles to look attractive with narrow margins between them, a 1/16″ grout line is suggested. Even though they are considered to be challenging to master, the colors you use must correspond; otherwise, it will be quite obvious using this grout line. If you do not search for professional assistance with the 1/16″ line, it will be more difficult to conceal your errors. However, if you do it accurately, the distance will be sharp, and the floors or walls will look fantastic.

What to Consider While Picking a Grout Size

So, in the case of grout lines, you must keep a few essential guidelines in mind. However, it simply depends on what kind of design and structure you would like on the surface of your rooms.

For example, a rule when using narrow grout lines and filling them with good colours that complement the tiles, 18 by 18-inch tiles or larger format tiles appear to look better. When thin grout lines are used, larger tiles appear as if they are a single tile slab on the floor.

So how do you determine questions like “How big should my grout lines be?” Some of the elements you must consider are:

Size of the Tiles

Consider the tile size when deciding on a grout size. The dimensions and thickness of larger handcrafted tiles vary, necessitating a large grout joint to hide the inconsistencies and provide a more consistent installation. Smaller tiles, such as 6×24, require smaller grout lines due to their precise nature of installation and lack of visual style.

Size Variation Among the Tiles

Some tile formats are more noticeable than others, and some are thicker. As a result, the tile size must be considered when choosing a grout line for these tiles. The size of the spaces where the tiles are placed grows larger. Because the tiles are closer together, they appear smaller. For handmade tiles, larger grout spaces are recommended to account for size and thickness variations.

Surface for Installation

After that, consider where you want to place the tiles. Because larger grout lines require more grip, the slope of the surface should be thoroughly examined. Straightening the surface prevents grout drooping from one tile to the next and reduces the likelihood of irregular tile installation. When it comes to floor installations, for example, wider grout lines should be used to ensure adequate traction.

What Size Trowel Should I Use for 6×24 Tile

A 1/2″ x 1/2″ notch trowel that is squared in shape is preferable for implementing 6 by 24-inch tiles. You can use a 14″ x 38″ notch trowel as well, without forgetting to use mortar to plug the bulges in the centre of the tiles.

How Big Are the Lugs on Tiles

Wall tiles that are styled 4/4″ are usually used in spaces like bathrooms or kitchens as a form of self-spacing. Lugs are small protrusions on the tiles that are located at the edges. They are there for when tiles are placed together; they keep the tiles in line by separating them by a distance. They are usually 1/32 to 1/16 inches in width.

Wrapping Up – What Size Grout Line for 6×24 Tile

Remember, the grout space on your floor or wall is a critical element. It occupies cavities, relieves stacking stress, and straightens the tiles. Once the grout dries, the tile can flake out at a stress point if the grout line is too narrow. If you have a small grout space, stress from people or objects in the house can be a concern.

When the grout lines are too tight or too wide, it can cause issues with the tiles, making them chip. But if you’ve read this article thoroughly, you will know that the narrower the grout lines, the more noticeable the difference between your tiles.
