Tile Pattern Calculator — Waste by Layout Pattern

Herringbone pattern runs at 45° to the walls, meaning every tile at the edges needs to be cut at an angle. This creates many small triangular offcuts that can't be reused. Typically ~18% waste is allowed vs 10% for a straight grid, in line with BS 5385 and standard UK tiler practice. The waste increases further in small or awkwardly shaped rooms where there are more edge cuts relative to the area — plan for 20–22% in those cases.

Brick bond (running bond/offset) is the most popular pattern in the UK — it's classic, hides imperfections in wall flatness, and suits the popular metro/subway tile format. Each row is offset by half a tile width. Waste is moderate at 12%. Straight grid is simplest with 10% waste. Herringbone is trendy but needs more skill and waste.

Diagonal tiling runs at 45° to the walls. Start by snapping chalk lines from corner to corner to find the centre. Lay the first tile at the intersection, then work outwards. All edge tiles need 45° cuts. Use a wet saw with an adjustable fence for consistent angle cuts. Allow 15% waste for edge cuts.

Rectangular tiles with a 2:1 ratio work best — 100×200mm, 150×300mm, or 200×400mm are ideal. Larger tiles (300×600mm) create a dramatic herringbone but need more precision. Small mosaics on herringbone mesh sheets are easiest for DIY. The pattern works on both floors and walls.

Yes — combining patterns is a popular design technique. For example, a herringbone feature panel within a straight-laid floor, or a diagonal border around a straight field. Plan the transitions carefully and account for waste separately for each pattern area. Transition strips or a grout line can define the boundary between patterns.
