Tile Spacing and Layout: Getting It Right First Time

Poor tile spacing and layout planning is one of the most common reasons a DIY tiling job looks amateur even when the tiling technique itself is fine — inconsistent joint widths and badly placed cuts are far more noticeable to the eye than most people expect, especially once grout highlights every line.

Why layout planning matters

Tiling straight from a corner without planning almost always leads to an awkward, narrow sliver of cut tile at the opposite end of the wall or floor — visually the worst possible outcome, since the eye is naturally drawn to interruptions in a pattern. Planning the layout first, before any adhesive goes on the wall, lets you control where cuts fall and keep them balanced, minimal, and away from the most visually prominent areas.

How to plan a layout

Dry-lay a row of tiles (with spacers) across the wall or floor without adhesive, starting from the centre point or the most visually important feature (such as directly above a bath, or centred on a chimney breast). See how the tiles land at each end, and adjust your starting point until cut pieces at both ends are roughly equal in size and reasonably wide — ideally at least half a tile width, so slivers are avoided. For floors, also check how tiles will meet doorways, thresholds, and any fixed features like a kitchen island, since these are natural focal points where poor alignment is most obvious.

Choosing your joint width

Grout joint width is a mix of practical necessity and style choice. Rectified (precision-cut) tiles with very straight, consistent edges can use narrow joints, sometimes as tight as 1.5-2mm, for a sleek, almost seamless look. Standard (non-rectified) tiles have naturally slightly irregular edges and need a wider joint — typically 3-5mm — to accommodate that variation without looking uneven. Natural stone and handmade tiles often need even wider joints, sometimes 5-8mm, both to accommodate size variation and because it suits their more rustic character. Wider joints also use more grout, a modest but real cost difference on a large area.

Common layout patterns

• Grid/stack bond — tiles aligned directly above and below each other, giving a clean, modern, minimal look, but showing any slight size inconsistency between tiles more obviously than an offset pattern.
• Brick bond (offset by 50%) — the classic offset pattern, forgiving of minor tile size variation and suiting most standard rectangular tiles.
• Herringbone, metro offset, or other decorative layouts — see our dedicated guide to herringbone, metro and subway tile patterns for these more involved options, which need more careful planning and generally more tile wastage.

Keeping spacing consistent

Tile spacers — small plastic crosses or wedges placed at each corner — are the standard way to maintain consistent joint width as you work, and they're inexpensive enough that there's no good reason to skip them, even on a small job. Check level and alignment with a spirit level regularly as you go, not just at the start, since small drifts compound across a wall or floor and are far easier to correct a few tiles in than after an entire wall is tiled.

Large format tiles need extra care

Larger tiles are less forgiving of an uneven substrate, and lippage (where adjacent tile edges sit at slightly different heights) is more visually obvious with bigger tiles. See our guide comparing large format vs small tiles for more on the extra preparation and technique large tiles typically need.

Getting professional help with layout

For anything beyond a simple, small, square area, a professional tiler will typically plan the layout as a matter of course, and it's a reasonable thing to discuss and agree on before work starts even if you're hiring the job out — ask to see how cuts will fall at prominent edges before tiling begins, so you can flag any concerns while it's still easy to adjust.

Wall layout vs floor layout

Wall layout planning generally starts from the most visible feature at eye level and works outward and downward, since anything above eye level or below knee height is far less noticeable if the cuts there are slightly less perfect. Floor layout planning generally starts from the room's main doorway or focal point (such as a bath or kitchen island) and works towards the walls, since the eye tends to register the floor as you walk into a room before it registers the edges.

Working around fixtures and obstacles

Pipework, sockets, extractor fans, and other fixtures need their own careful planning within the layout — cutting a neat hole for a pipe or socket in the middle of a tile takes more skill than a straight edge cut, and where possible, positioning a joint line to fall near (rather than through) a fixture can make the cut simpler and less visually obtrusive. Discuss fixture positions with your tiler before layout is finalised if any fittings (like a shower mixer or toilet roll holder) haven't been fixed in place yet.
