Measure the horizontal width of a finished ripple repeat, not the length along its zigzag edge.

## Before you start

Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.

## How to do it

1. **Read repeated crochet instructions** — Separate what consumes an existing stitch from what creates a new stitch or chain space. Expand one repeat before repeating it across a row.
2. **Make a representative crochet swatch** — Sample the actual stitch pattern, working direction and finishing method. A plain-stitch square cannot establish the gauge of a textured or mesh project.
3. **Calculate crochet stitches for a width** — Multiply finished stitches per centimeter by the target width, then fit the pattern repeat and edge stitches. Recheck the rounded result as a physical width.
4. **Find growing or shrinking edges** — Compare row counts before changing tension. Accidental first-stitch additions and missed last stitches create systematic width changes.

## Try this example

If a full ripple repeat advances 12 cm, eight repeats give about 96 cm before side treatment. Check peak increases and valley decreases on the sample so the repeat count remains stable.

## Check your result

- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.
