Crochet Stitch Height Reference
Stitch heights, turning chains, and height ratios — plus a vertical stitch count calculator.
Stitch Height Reference Chart

| Single Crochet | sc | 1 | 1× (baseline) | Short, dense stitch; baseline for comparison |
| Half Double Crochet | hdc | 2 | 1.5× | Slightly taller than sc; has a distinctive third loop |

How to Use
- Use the reference chart to compare stitch heights and find the correct turning chain count for any stitch.
- In the calculator, enter your target height (e.g. 12 inches), rows per inch from your gauge swatch, and stitch type to get the exact row count needed.
About Stitch Heights
Stitch height determines how many rows fit in a given vertical measurement. Taller stitches like treble crochet work up faster vertically — you need fewer rows to reach the same height as with single crochet. Turning chains at the beginning of a row compensate for the height of the stitch and keep your edges straight.
Note: Some patterns treat the turning chain as the first stitch; others do not. This affects stitch counts per row.
Results are estimates. Actual row heights vary by yarn weight, hook size, and personal tension.
