How to set amigurumi gauge and check finished size

Gauge connects a digital amigurumi recipe to the yarn and hook in your hands. In the amigurumi designer, you can start with a yarn estimate or enter measured stitches and rounds per 10 cm.

The 3D view estimates the finished shape. A measured sample makes its size estimate more useful, but stuffing and tension still affect the result.

1. Measure a straight section

Use the yarn, hook and tension intended for your project. Count stitches and rounds across a known distance on a straight section before stuffing. Avoid measuring across increases, decreases or a rounded tip.

Convert each measurement separately:

• Stitches per 10 cm = counted stitches ÷ measured width in cm × 10.
• Rounds per 10 cm = counted rounds ÷ measured height in cm × 10.

For example, 12 stitches across 5 cm gives 24 stitches per 10 cm. Fourteen rounds over 5 cm gives 28 rounds per 10 cm. These are example measurements, not recommended settings for every yarn.

2. Apply measured gauge

Open File → Yarn and gauge, or choose the yarn settings button in the desktop tool rail. On a phone, first open the editor menu, then File.

Enter Stitches per 10 cm and Rounds per 10 cm. Add your yarn name and hook size so you can identify the setup later. Press Apply measured gauge; changing the fields alone does not apply them.

Check the gauge status after applying it. Use yarn estimate, or choosing another yarn preset, replaces measured gauge with the preset estimate.

3. Know which value stays fixed

Component type	When gauge changes
Custom component	Keeps its stitch recipe; estimated dimensions change.
Ready-made part	Keeps its size settings; stitch and round counts are recalculated.

A custom 24-stitch tube stays a 24-stitch tube. If your stitches are wider, the tube becomes wider. A ready-made part with a width setting instead asks the generator to find counts for that width at the new gauge.

For mixed creations, inspect the proportions and attachments after changing gauge. Recheck any painted round ranges because recalculated counts can move a stripe relative to the shape.

4. Compare a small physical sample

Start with a small piece before crocheting the whole animal. Compare its actual size with the preview using the same measuring method. Note how firmly you stuffed it and whether your tension changed.

Curved components use mixed sc/hdc rounds and need a physical check of their bend as well as size. The preview uses an estimated difference between stitch heights. A scarf is worked flat, so measure a separate flat sample if its fit matters; flat and in-the-round gauge may differ.

The designer’s generated recipes are not a substitute for test crocheting a pattern you plan to publish. Record your materials, check the instructions and ask another crocheter to follow them before describing the pattern as tested.
