An odd checkerboard does not split tile colors equally.
Which color receives the extra position in an odd-by-odd layout?
Use the matching calculator
Use this decision sequence
- Use the specified row and column counts, including edge positions.
- Identify the color assigned to the top-left position.
- Count alternating positions rather than splitting the total area into two equal needs.
- Round each color count by its own pack size and show surplus separately.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Even total positions | Colors split equally. |
| Odd-by-odd grid | Starting color receives one extra position. |
| Color-specific packs | May round to different purchase counts. |
Worked comparison
An illustrative three-by-three grid has nine positions. With the first color in the top-left position, counts are five and four. If each color comes in packs of four, purchases are two first-color packs plus one second-color pack: three total. A five-and-four position count is the pattern’s exact quantity, not an arbitrary percentage allowance.
Check before using the estimate
The grid count must already include the intended edge layout; reusing cut pieces is a separate checked cut plan.
