1/16 vs 1/32 Grout Line: Making the Right Choice for Your Tile Installation


When it comes to tile installations, one of the crucial decisions you need to make is choosing the right grout line size. The grout lines play a significant role in the overall aesthetics and durability of your tiled surface. In this article, we’ll dive into the differences between the 1/16 and 1/32 grout lines, and help you understand which one might be the best fit for your project.

Understanding Grout Lines

The Importance of Grout

Grout serves as the filler between tiles, preventing moisture and debris from penetrating the gaps and keeping tiles in place. It also contributes to the visual appeal of the installation by defining the layout and pattern.

Grout Line Size Options

Grout lines come in various sizes, with 1/16 and 1/32 being among the most common options. The size you choose can significantly impact the overall look and feel of your tiled surface.

Pros and Cons of 1/16 Grout Lines


  1. Enhanced Aesthetics: Smaller grout lines create a seamless appearance, allowing the tiles to take center stage and giving the space a modern, sleek look.
  2. Accurate Tile Alignment: With minimal spacing, the tiles can be precisely aligned, resulting in a professional finish.
  3. Ideal for Intricate Patterns: If your design involves intricate tile patterns, a 1/16 grout line can help maintain the pattern’s integrity.


  1. Less Forgiving: Smaller grout lines offer less room for error during installation. Any imperfections in tile size or alignment can become more noticeable.
  2. Limited Space for Grout: The narrow grout lines may not accommodate heavily textured or irregular tiles, making installation challenging.

Pros and Cons of 1/32 Grout Lines


  1. Subtle Division: 1/32 grout lines provide a subtle division between tiles, giving each tile a distinct presence without overwhelming the overall design.
  2. Easier Maintenance: The smaller grout lines are easier to clean, as there’s less surface area for dirt and grime to accumulate.
  3. Versatile Installation: Suitable for various tile sizes and materials, making it a versatile option for different design styles.


  1. Less Alignment Precision: Achieving perfect alignment with 1/32 grout lines can be trickier, especially with larger tiles.
  2. Less Visual Impact: While providing a clean look, 1/32 grout lines may not have the same visual impact or definition as larger grout lines.

Choosing the Right Grout Line

To decide between 1/16 and 1/32 grout lines, consider the following factors:

  1. Tile Size: Larger tiles might benefit from slightly larger grout lines to accommodate alignment.
  2. Design Preference: Are you aiming for a contemporary, seamless appearance or a more traditional, defined look?
  3. Skill Level: Your experience with tile installation can influence your choice; smaller grout lines demand higher precision.


The choice between 1/16 and 1/32 grout lines depends on your specific project requirements and design preferences. While 1/16 grout lines offer a modern, seamless look, 1/32 grout lines provide subtle division and easier maintenance. Ultimately, the decision should align with your vision for the space and your level of expertise.
