About Opuslay
Why I built Opuslay
I'm Xavier, an engineer, and I built Opuslay to answer the question that matters most when you're about to order tile: how does the pattern actually fall in your room? Where do the cuts land, which tiles repeat, how does a Versailles or herringbone layout meet your walls?
So Opuslay lays the pattern out for real — tile by tile, from an anchor point you choose — and counts exactly what it places. Every number you see traces back to real geometry, at full precision.
What Opuslay does for you
- Real tessellation. Each pattern is placed across your actual room dimensions, tile by tile from your chosen anchor point. Your quantity — and your offcuts — are counted from where the cuts really land in your room, piece by piece.
- One format or many, same engine. The library runs from a plain 24x24 monoformat to a Versailles built from four interlocking sizes. Single tile or multi-format module, the engine tessellates it the same way and counts each piece it places.
- Straight-set or running bond. Set the joints aligned in a grid, or offset them in a running bond — your choice. Offsets follow ANSI A108.02: a half-tile offset for small formats, and a third-tile offset for large-format tile, the standard way to keep lippage down.
- Beyond rectangles. Herringbone and chevron, penny rounds, octagon and dot — the engine works in true shapes, generating each tile's real outline and checking it the same careful way it checks a plain square.
- Laid on the diagonal. Turn any pattern 45° for a diagonal set. The edge cuts are recalculated from the tilted layout itself, so the counts reflect how the pattern really meets the walls at an angle.
- Color it in. Preview any pattern in two, three or four colors — watch a checkerboard, a pinwheel or a bordered floor take shape before you commit to an order.
- Floors and walls. Lay a floor, or set up to three walls side by side — each with its own width and starting point. The recap totals them for you in one place.
- Geometry that's been checked. Every pattern in the library is defined by raw geometry in centimeters and verified before it ships: the module's area equals its repeat, edges meet cleanly, and every tile sits flush.
- Inches or metric, exactly. Inch and metric throughout, with a toggle on every page. Inch conversions use the exact 2.54 factor, precise to the millimetre.
- Results you can order from. Quantities come as pieces plus area (sq ft / m²) — the two numbers you actually place an order with.
Get in touch
The whole pattern library is free to use — if it helps you order with confidence, it's done its job. And when you want to go further, the new Custom Tile Layout Planner lets you design your own layout, tile by tile, and run it through the very same engine. It's a premium tool — and it's free for everyone during the launch period.
