Herringbone Tile Calculator

Calculate how many tiles you need for a herringbone layout. Herringbone patterns require 15% waste (minimum) due to the angled cuts at every border.

Herringbone works best with rectangular tiles (e.g. 4×12 subway, 3×6, 2×8).

Why herringbone needs 15% waste

A herringbone pattern sets tiles at 45° angles. Every tile that meets a wall or border must be cut on the diagonal, and most of those off-cuts can't be reused elsewhere in the pattern. This creates significantly more waste than a straight-grid layout.

Best tile sizes for herringbone

  • 3×6 subway: Classic, works on floors and walls.
  • 4×12: The most popular herringbone format for floors.
  • 2×8 or 3×12: Gives a tighter, more intricate pattern.
  • Large plank (6×24): Dramatic effect, fewer grout joints, but harder to install.

Installation tips

Snap a centerline and dry-lay at least 3 rows before spreading mortar. Herringbone alignment errors compound quickly — getting the first rows perfectly square is critical. Use tile spacers consistently and plan your cuts before you start.

Frequently asked questions

Is herringbone tile harder to install?

Yes, herringbone is more labor-intensive than straight layouts. Each tile is set at a 45° angle, and every border requires angled cuts. Expect installation to take 30–50% longer than a straight grid. Many installers charge a premium for herringbone.

How much more tile do I need for herringbone vs straight?

Budget at least 15% waste for herringbone versus 10% for a straight layout. That's roughly 5% more material. For a 200 sq ft room, that's about 10 extra sq ft of tile.

Can I use square tiles for herringbone?

Technically yes, but the pattern looks best with rectangular tiles at a 2:1 or 3:1 length-to-width ratio. Square tiles set at 45° create a diagonal/diamond pattern, not a true herringbone.
