Tile layout calculator — avoid thin cuts at the wall
Enter the room and tile size to see a practical laying plan, whole and cut pieces, material order and the start position that avoids narrow strips where possible.
Layout preview
The purple outline is the room. Dark tiles are cut on site.
Comparison only: it checks other patterns, rotations and start modes with the same inputs. It does not change the plan above.
How to use the tile layout calculator
- Step 1
Enter the surface
Add the finished width and length in millimetres.
- Step 2
Set the tile and joint
Choose the tile or paver size, joint and waste allowance.
- Step 3
Compare layouts
Switch pattern or rotation and use the recommended balanced start.
How the layout works
The calculator tests possible start offsets and selects the one with the widest smallest edge piece. Material is estimated from surface area plus your allowance; the drawing is a planning aid, not a cutting schedule for irregular rooms.
Scope and limits
For rectangular surfaces and rectangular tiles or pavers in millimetres. Diagonal is a visual planning preview; openings, slopes, borders and structural movement joints need a site-specific setting out.
This is a geometric layout, not a setting-out plan. It excludes L-shaped rooms, openings and thresholds, herringbone or modular patterns, drains, skirting, furniture, borders and movement-joint design; the waste figure is not a substitute for an installer’s allowance.
Frequently asked questions
Why is the recommended start not at the wall?+
A centred start can split the remainder between two edges, avoiding a fragile narrow strip on one wall.
Does this replace a site setting-out plan?+
No. Check actual room dimensions, movement joints, thresholds and manufacturer guidance before cutting.
