To calculate the number of tile spacers you need, multiply the total number of tiles in your project by 4 (one for each corner). Always add an extra 10% to 15% to cover perimeter cuts, pattern variations, and unexpected losses.

For 12x24 inch tiles, use 1/8-inch (3mm) spacers for a balance of aesthetics and ease of installation, or 1/16-inch (1.5mm) for a modern, minimal-grout look with rectified (perfectly straight-edged) tiles. While 1/16 inch is popular for a seamless look, 1/8 inch is safer for beginners to hide minor tilesize variations.
For 12x24 inch tiles, a 1/8-inch grout joint is generally considered the best, most versatile, and standard choice, particularly for floors to handle minor irregularities. If using rectified (precisely cut) tile, a narrower 1/16-inch joint is acceptable for a modern, sleek look, while non-rectified tiles may require 3/16-inch for a better finish.
The 1/3 rule for tile (often called a 33% offset) is a layout guideline that recommends staggering your tiles by one-third of their length in each row, rather than the traditional 50% (half) brick pattern.
Top 13 Tiling Mistakes & How to Avoid Them
The herringbone pattern is widely considered the hardest tile pattern to install. Because the rectangular tiles interlock at precise 90-degree angles to form V-shapes, even a millimeter of misalignment will cause the entire pattern to drift off-center, ruining the alignment of grout lines and requiring flawless cuts.
One of the most frequent grouting mistakes is improper mixing and application. Grout is a precise material, and getting this step right is crucial for its strength and adhesion. Incorrect Water-to-Grout Ratio: Adding too much or too little water can significantly weaken the grout.
Usually ⅓ stagger or stacked is recommended. ½ stagger is often discouraged for lippage concerns resulting from the bow of the tile. Depends on the space, generally 3rd stagger works out best with 12x24 tho.
The most common standard tile spacer sizes range from 1161 over 16 end-fraction116" to 38three-eighths38". The best size depends on your tile type and application:
For installing 12×24 floor tiles, a 1/2-inch square-notched trowel is recommended. This size provides enough adhesive for a strong bond with the substrate, accommodating any surface irregularities.
The easiest way to calculate how many tile spacers are needed is by multiplying the number of tiles you have by the amount of corners on each tile. Try using our chart to calculate how many spacers you'll need.
For a floor tile, the thinnest practically recommended grout line is 1161 over 16 end-fraction𝟏𝟏𝟔 of an inch. While some installers attempt 1321 over 32 end-fraction132 of an inch in perfect conditions, the Tile Council of North America (TCNA) generally establishes 1161 over 16 end-fraction116 inch as the minimum to prevent chipping, "lippage" (uneven tile edges), and cracking.

Tile flooring is one of the most durable options available and can last 20 to 50+ years, with many high-quality floors enduring a lifetime. Its longevity largely depends on the material, installation, and care:

There is no single mandatory direction for laying 12x24 tiles, but the best approach depends on the room's dimensions and your design goals. Generally, lay them with the long side parallel to the longest wall to elongate the space, or perpendicular to the main entrance for a welcoming feel.
Uneven subfloors, out-of-plumb walls, or skipping backer boards can all lead to lippage, cracking, or even full-on tile failure. Start with a level surface.
For 12×24 tiles, the standard and most recommended spacer size is 𝟏/𝟖 inch. This size provides enough room for the grout to securely grip the tile edges while remaining visually crisp and modern.
Bleach can also weaken grout and damage any sealer that's been applied. Over time, bleach makes grout more porous, which means it gets dirty even faster. Why to avoid: Like bleach, ammonia strips away protective sealers. It can also discolor grout and weaken the integrity of the grout over time.
Unless the design is specifically meant to look rugged, uneven, or is a mosaic pattern, then crooked tiles are the first sign of a bad tiling job. Crooked tiles occur for several reasons – for example, grouting may be uneven or the installer may have neglected the use of tile spacers when allowing the grout to set.
The herringbone pattern is widely considered the hardest tile pattern to install. Because the rectangular tiles interlock at precise 90-degree angles to form V-shapes, even a millimeter of misalignment will cause the entire pattern to drift off-center, ruining the alignment of grout lines and requiring flawless cuts.
It asks: Can you seamlessly tile an endless surface with a single shape (an “einstein”) in such a way that the resulting pattern is never repeated? Such a “proto-tile” was first discovered in 2022 by the English amateur mathematician David Smith. Empa researcher Karl-Heinz Ernst is neither a mathematician nor a tiler.
Traditional Hexagon Styles
Black and white hexagon mosaic tiles are one of the most timeless tile styles in existence.
Some shapes, such as ovals or circles, can not be tiled together to create a pattern without space in between them.
