Tile Installation Options & Gap Sizing

Tiles come in thousands of materials, shapes, and sizes. Understanding the variables between a mosaic backsplash and a large format porcelain floor helps guarantee that you calculate your project correctly without coming up short or purchasing too much material.

Tile Size

Tile size ranges from small 3/8" mosaics to massive 24" × 48" slabs. Large tiles make smaller rooms appear bigger and more open because there are fewer visible grout lines. However, large tiles also result in more wastage during edge cuts, while smaller tiles are easier to maneuver around complex shapes and fixtures.

Layout Patterns

The layout you choose dictates how much tile you need. Linear grids are standard. Running bond layouts (like a brick wall) involve offset rows. Herringbone layouts place tiles at angled 45° or 90° patterns. Both running bond and herringbone layouts require more cutting at the edges, increasing the amount of waste material generated.

Understanding Gap Size (Grout vs Overlap)

Floor or wall tiles are typically installed with gaps between the tiles because standard tiles are slightly uneven and would not fit together tightly without popping out. These gaps are filled with grout (a form of concrete) and range from 1/16" to 1/2" in width.

You can achieve smaller, nearly invisible grout lines by purchasing "rectified" tiles—tiles that undergo additional precision factory cutting to ensure perfect uniformity.

Negative Gaps (Overlapping)

In certain construction projects, such as installing roofing shingles or wood wall siding, tiles overlap each other to prevent water leakage. Our calculator supports this logic. If you are calculating an overlapping material, simply input a negative value in the Gap Size field.

Tile Material Options

Material Classification	Common Applications & Features
Ceramic & Porcelain	The most cost-efficient and versatile options. Highly durable and available in countless printed styles.
Glass Tiles	Visually striking and reflective. They crack under heavy pressure, so they are restricted to backsplashes and walls.
Quarry Tiles	Unfinished, rough surfaces that provide excellent grip. Perfect for outdoor patios or restaurant kitchens.
Natural Stone	Includes marble, granite, and slate. Very expensive but offers unique, irreplicable natural veining. Edges can blend seamlessly into matching grout.
