1/16 and 1/8 grout lines are the sizes most frequently used when installing tiles.
The dimensions of the grout lines are often discussed first before mounting tiles be it on walls or floors, but in most cases, homeowners go for the ones they prefer. However, there are specific rules that you must know when deciding on the size of the grout lines.
This post will explain the differences between 1/16 and 1/8 grout lines and give you the needed closure. Knowing these differences will help you determine how and where to install these two, the kind of tiles best suited for use alongside them, and much more.
Firstly, what is grout?
Grout is a thick liquid used to seal joints or support existing facilities.
Grouts are commonly used in household tiling work, including sealing joints of bathroom walls, floors, and kitchen tiles.
1/8 vs 1/16 Grout Lines
Deciding carefully on the grout width before you mount the tiles is essential. You don’t want the grout lines too wide or too narrow, as it takes the beauty off of your tiles.
1/8 and 1/16 grout lines are the acceptable sizes when installing tiles in the kitchen and bathroom. If you prefer a standard appearance, tile experts suggest that the 1/16” grout lines are most suited for walls, while the 1/8” works best for floors.
Experts recommend using 1/16 grout lines for mounting small tiles like the 4/4-inch tiles or average-sized tiles on kitchen and shower walls. Professionals also prefer using the 1/8 grout lines for more oversized tiles like 18/18 inches, regular size variation, or floor tiles with lugs.
1/8 and 1/16 grout lines thus, have several discrepancies distinct from each other, and you will find that they differ in their thickness, ease of repairing grout gaps, and locations for laying them.
Differences Between 1/8″ and 1/16″ Grout Lines
Thickness
The comparable thickness and diameter of the grout lines decide what tiles to use. 1/8-inch grout lines are thicker and broader than grout lines 1/16”.
It is easier to install and organize 1/8 grout lines than 1/16 grout lines, and there is less chance of messing up. It is so because their thickness allows less possibility for grout irregularity that affects the tiling on drying.
Also, 1/8” create a sturdier and clean edge finishing than 1/16 grout lines. 1/16-inch grout lines are thinner and are mainly used for tiles with tight edges and joints since they are closed in. Thus, they are suitable for smaller tiles because such tiles require less grout to attach them.
Capacity to Service Grout Lines
The capacity to service grout lines depends on the grout joint’s tightness or broadness.
When laying 1/16 grout lines, you should remember that it would be tough to service or regrout grout joints differently. 1/16-inch grout lines are tight and limited, so you should set them in areas where you don’t require servicing the joints. For instance, you can use 1/16 grouts in arid regions, including the halls in your home.
On the other hand, the 1/8 grout line is ideal for regrouting the joints since it is effortless to pass a machine through and less complicated to repair and make alterations in 1/8 grout joints.
Therefore, you can mount 1/8” in damp locations or places inclined to wetness, such as the shower. In such a manner, you can regrout or service when needed.

Similarities Between 1/8″ and 1/16″ Grout Lines
Rectified or Sharp Edge Tiles
1/8 and 1/16 grout lines don’t share many similarities between them. These two grout lines have different widths, although they are similar in their ability to work excellently with the same kind or quality of tiles. They are both suitable with rectified edges or finely-cut tiles.
Tiles with uniform edges can adjust with small or tight grout lines since they are cropped correctly. You will find just a bit of irregularity in uniform tiles. Therefore, such tiles can work well with small to average grout lines.
For instance, a 1/16-inch is suitable for mounting glass tiles since glasses have clean-cut edges allowing for a tighter installation. Likewise, you can use a 1/8-inch with rectified tiles to let the tile design flow easily from one tile to another.

Yes, the 1/16″ grout line is ok in many tiling jobs. Experts recommend that grout lines not be smaller than 1/16-inch as that can make your tiles look inelegant.
Grout lines having 1/16-inch width are suitable for numerous tiling works. When laying tiles, you can use 1/16” as they work adequately with most tiles. However, using smaller porcelain tiles is recommended.
Since the 1/16-inch grout lines are thin, they pair perfectly well with tiles that measure up to 8/8 inches. A 1/6″ grout line works best in rectified tiles since such tiles have uniform edges, and their thin grout lines allow for tighter installation.

Any grout lines measuring less than 1/8-inch are perfect for pairing with rectified tiles since such tiles come with clean edges and require less grout. Thus, only a small space is needed between each tile, so a grout line of 1/8″ area is suitable as it allows the design to flow adequately from one tile to another.
How Large Should Grout Lines Be
Grout lines on a tile should be 1/8-inch or larger.
Anything smaller than the 1/8 grout lines is perfect for rectified tiles that require no or less grout. The thin line almost becomes invisible if you use it with tiles that have decorated designs and textures, and so it all depends on the kind and size of tiles you’re installing.
In contrast, bigger grout lines take the beauty of the tiles away, resembling a grid instead. The larger the line is, the more conspicuous it will be. Also, a big grout line means you must give extra attention while scrubbing the tiles.
Regardless of their irregularities, it is entirely up to you to choose the size you prefer but make sure the grout lines on the walls and floors accentuate each other. The options are endless; you can bring out your creativity and mix and match to suit your unique style.
