3x12 Herringbone Pattern
The 3x12 herringbone pattern lays a slim plank tile at a 90° angle to itself, forming the same zigzag joint structure as 2x8 herringbone on a slightly longer plank — a close match to the proportions of the wood parquet the pattern was originally designed for.

Adhesive & grout
- Thin-set adhesive: ≈ 24.4 kg (2 × 50 lb bags) — recommended trowel: 10mm notch
- Grout — the tile sets the joint width, not you:
- ≈ 5.7 kg (1 × 25 lb bag) — 3mm joint, rectified / tight-set tile
- ≈ 9.5 kg (1 × 25 lb bag) — 5mm joint, natural or non-rectified tile
Adhesive: allow a little over on an uneven substrate, or if you back-butter large tiles — both eat more than a flat bed.
Grout: the 25 lb bag is the usual size (10 lb for small jobs). Buy it in one go and stick to a single bag size: bags from different batches can dry to slightly different shades.
It's the tile that decides the joint, not the setter — dry-lay a section to find your width. Assumes 9.5mm tile depth; adjust for your product — thicker tiles need more.

About the 3x12 Herringbone Pattern
3x12 sits between the classic 2x8 herringbone size and the wider plank formats like 4x12 and 6x24, offering a middle ground for installers who want a slightly longer plank without moving into large-format territory.
Frequently Asked Questions
How does 3x12 herringbone compare to 2x8 herringbone?
Both use the same 90° zigzag structure — 3x12 is a slightly longer, narrower plank, giving a marginally more elongated look to each zigzag segment.
How much waste should I allow for 3x12 herringbone?
Plan for around 15-20% waste, typical for herringbone at any size, to cover the angled cuts needed at room edges.
Is 3x12 herringbone suitable for bathroom floors?
Yes — like other herringbone sizes, 3x12 is commonly used in bathrooms and other wet areas to reproduce a parquet look without real wood.
