Why a 50% Tile Pattern Can Cause Problems (And What to Do Instead)
Why a 50% Tile Pattern Can Cause Problems (And What to Do Instead)
What Do We Mean by a 50% Pattern?
Also known as “half‑bond” or “brick‑bond”, each tile overlaps the one below by half its length. It’s classic—but not always wise for long or large tiles.
Why It’s Risky with Big Tiles
Long rectangles and large‑format tiles can have a slight bow. The 50% overlap aligns peaks with troughs, creating lippage—raised edges that cast shadow lines and feel uneven underfoot.
Better Choices
- ≤ 1/3 offset: The safest stagger for long or large tiles.
- Straight lay: A contemporary, geometric look that’s fast to install.
- Herringbone (smaller planks): Adds movement without 50% overlap.
Pair your layout with the right levelling system, adhesive and grout for a flatter, longer‑lasting finish.
When Is 50% Acceptable?
- With small subway tiles that have minimal bow.
- On very flat substrates with good preparation and manufacturer approval.
Practical Tip
Always dry‑lay a few rows. If joints “peak”, switch to a ≤ 33% stagger or try a straight layout.
Bottom Line
50% looks traditional, but for long planks and large rectangles it often compromises the finish. Choose a layout that supports flatness and durability.
