Half-offset tile laying: the brick pattern explained

Offset patterns · 6 min read · updated 5 November 2026 · Written by Tilelico

Each row starts half a tile further along than the last. This offset, the brick pattern, breaks up joint alignment and is more forgiving of an imperfect wall than a straight lay.

Real example · calculated by Tilelico

Kitchen with an island of 4.20 × 3.60 m, 30 × 60 cm, 3 mm joint

WholeCutCut under 100 mmIsland

The island in the middle of the kitchen multiplies the cut sizes: its four sides break into tiles as well as the room edges. The layout stays free of narrow cuts, but that variety needs preparing before cutting starts.

Calculated result

Area covered: 13.30 m²

Setting out and products

Starting point 131 mm from the west wall and 293 mm from the north wall, then a 303 × 603 mm repeat. Estimated products: 47 kg of adhesive and 2.6 kg of grout.

Reproduce it in Tilelico

1Draw a 4.20 × 3.60 m rectangle, then add in the centre: Island.
2Choose the covering: 30 × 60 cm, 3 mm joint.
3Select the “Half offset” pattern.
4Set the distribution to “Balanced cuts” and the margin to 10%.

When to choose it

It is a classic for moderate rectangular sizes, especially in kitchens and utility rooms.

Best forModerate rectangular sizes such as 30 × 60, and walls that are not quite square.
Avoid ifYour tiles are long or heavily rectified: many manufacturers then limit the offset to a third because of the tile’s slight bow.

Preparing the job

Read the data sheet: it often states the maximum offset for the size, and it takes precedence over any site habit.

Locate obstacles such as an island or a column, and see what their outline demands before fixing the starting point.

Step by step

Step 1 — Mark the row axisSnap a line parallel to the reference wall: each run aligns on it.
Step 2 — Mark the offsetDraw a second line half a pitch away, so you do not recalculate it for each row.
Step 3 — Dry-lay two rowsLay them without adhesive to check the cuts at both ends.
Step 4 — Lay alternatelyBed the tiles, setting every other row from each mark, and check flatness between tiles.
Step 5 — Cut around obstaclesLeave these cuts until the end and transfer the cut list dimensions to each tile.

Mistakes to avoid

Neglecting lippageA tile’s slight bow peaks in its middle, exactly where the neighbouring row’s joint falls.
Measuring the offset from the wallThe wall is not a reliable reference: measure the offset on the line.

These pointers describe common practice, not imposed rules. The data sheet for your covering and for your installation products always takes precedence, and measurements taken on site are the reference.

Frequently asked questions

What is the difference between a half and a third offset?

The look and the risk of lippage. A half offset is more regular to the eye; a third reduces the effect of bow on long sizes.

Can a square tile be offset?

Yes, the calculation is the same. The result looks more like stonework.
