How this calculator works
The tile coverage never changes — a 12x24 tile is 2 sq ft in every layout. What changes is the number of tiles you cut and throw away. In a grid, most offcuts get reused at the opposite wall. In herringbone, almost none do.
Planning the layout: snap chalk lines through the exact centre of the room, dry-lay a full row in both directions, and shift the centre line so the cuts at opposite walls are equal and never thinner than half a tile. A sliver cut along a doorway is the single most common giveaway of a rushed job.
- Balance cuts on opposite walls — move the start line, not the pattern.
- Start herringbone from a centre line at 45°, not from a wall.
- Keep offsets on plank tile to 33% maximum to avoid lippage.
- Order all tile in one purchase so the dye lot matches.

Frequently asked questions
How much extra tile do I need for herringbone?
20% over the measured area. Every row ends in a 45° cut and the triangular offcuts almost never fit elsewhere.
Which tile pattern wastes the least?
A straight grid or a simple offset — about 10%. Both let you reuse the offcut from one wall to start the row at the other.
Does a diagonal layout really need 15%?
Yes. Turning the grid 45° means every perimeter tile is cut into two triangles, and only one of them usually gets used.
How do I plan a tile layout so the cuts look right?
Find the room centre, dry-lay a full row each way, then shift the centre line so opposite walls end with equal cuts no smaller than half a tile.
