Quilt Block Size Chart
Use this chart to estimate how many finished quilt blocks fit into common quilt sizes. These counts assume no sashing or borders and simple grid layouts.
| Block Size | Baby (36"×45") | Throw (50"×60") | Twin (70"×90") | Queen (90"×108") | King (108"×108") |
|---|---|---|---|---|---|
| 6" × 6" | 6 × 8 | 9 × 10 | 12 × 15 | 15 × 18 | 18 × 18 |
| 8" × 8" | 5 × 6 | 7 × 8 | 9 × 12 | 12 × 14 | 14 × 14 |
| 9" × 9" | 4 × 5 | 6 × 7 | 8 × 10 | 10 × 12 | 12 × 12 |
| 10" × 10" | 4 × 5 | 5 × 6 | 7 × 9 | 9 × 11 | 11 × 11 |
| 12" × 12" | 3 × 4 | 5 × 5 | 6 × 8 | 8 × 9 | 9 × 9 |
Note: These counts use ceiling division to show the minimum blocks needed to cover each quilt size without sashing or borders. The finished quilt top may be slightly larger than the target size. Use the block calculator or add borders for precise planning.
