This original BabyYarnie crochet baby cardigan sizing chart uses the supplied image only as a visual design brief. The crochet construction, measurements, arithmetic and wording are independently authored in US terms.
This free tutorial is written as an original measured construction rather than a color-only variation. Read the complete pattern before beginning, make a washed gauge swatch, and record the selected size and every adjustment. The stitch audit checks the written arithmetic, but it does not claim a physical sample or fit test.
Development disclosure: The supplied image is a mandatory visual reference only. This independently authored BabyYarnie crochet tutorial has a numerical stitch audit, but no physical sample test is claimed. Follow the written counts and make a washed swatch.

- Gauge: Worksheet swatch: 20 sc and 24 rows = 4 in after washing
- Terminology: US crochet terms only
- Construction: Measured gauge swatch plus finished-garment calculation worksheet
- Yarn Weight: Any baby-safe yarn matched by washed gauge

Abbreviations and Special Stitches
- ch: chain
- sl st: slip stitch
- sc: single crochet
- hdc: half double crochet
- dc: double crochet
- st(s): stitch(es)
- inc: two stitches in one base

Stitches-per-inch formula: washed stitches divided by measured inches. Required garment stitches: target finished inches multiplied by stitches per inch, rounded to the construction repeat. Row calculations use the same method with rows per inch.
Gauge, Sizing and Planning
Wash and dry a generous swatch in the same yarn, hook and colorwork method planned for the project. Measure only the relaxed center. If the stitch gauge is too tight, move up a hook; if it is too loose, move down. Recheck row gauge because length and shaping depend on it. Parenthetical counts follow the listed size order throughout. Place removable markers at all shaping points and recount before moving to the next section.

Instructions
Crochet and Wash the Measurement Swatch
- Ch 21. Row 1: sc in second chain and across; ch 1 and turn: 20 sts. The turning chain never counts.
- Rows 2–24: sc in every stitch, ch 1 and turn: 20 sts. Keep markers in the first and last stitch so no edge stitch disappears.
- Fasten off, wash exactly as the finished garment will be washed, shape without stretching and dry completely. Measure the central 4 inches, not the edges.
- Record stitches and rows across 4 inches. Divide each result by 4 to obtain stitches per inch and rows per inch. Do not use the yarn-label gauge unless your washed swatch matches it.
Choose Finished Measurements and Ease
- Use the chart as a planning range, then measure a well-fitting garment whenever possible. Add 1–2 inches of positive ease to the baby's actual chest; never size only by age.
- 0–3 months: 17–18 in chest, 9–10 in body, 5.5–6.25 in sleeve, 4–4.25 in armhole depth and 4.25–4.75 in neck width.
- 3–6 months: 18–19 in chest, 10–10.75 in body, 6.25–7 in sleeve, 4.25–4.75 in armhole and 4.75–5.1 in neck width.
- 6–12 months: 19–20 in chest, 11–12.5 in body, 7–8.25 in sleeve, 4.75–5.1 in armhole and 5.1–5.5 in neck width.
- 12–18 months: 20–20.5 in chest, 12.5–13.5 in body, 8.25–9.5 in sleeve, 5.1–5.5 in armhole and 5.5–5.9 in neck width.
- 18–24 months: 20.5–21.25 in chest, 13.5–14.25 in body, 9.5–10.6 in sleeve, 5.5–6 in armhole and 5.9–6.25 in neck width.
Convert the Chart to Crochet Counts
- Example: a washed gauge of 5 stitches per inch and a target 20-inch finished chest needs 100 body stitches around. A flat cardigan with two front bands could reserve 4 stitches for each band and distribute the remaining 92 across fronts and back.
- For a pullover, round the chest total to the nearest repeat that fits the stitch pattern. Recalculate the actual circumference from the rounded total before beginning.
- Multiply target body and sleeve lengths by rows per inch. Subtract ribbing or edging depth before calculating main-fabric rows.
- Check the armhole depth, neck opening and sleeve circumference as separate measurements. A correct chest number alone does not guarantee comfortable fit.
Finishing
- Attach the chart and washed swatch notes to the project bag.
- Measure the garment flat after blocking and compare all five dimensions.
- Use soft washable yarn, secure closures and keep garments out of infant sleep spaces.
Tips
- Age ranges are approximate; actual body measurements take priority.
- Swatch every stitch pattern and colorwork method separately.
- Round counts to complete repeats, then recompute inches.
- For gifting, choose adjustable cuffs and include care instructions.
Frequently Asked Questions
Is this a knitting chart?
No. This article is rewritten and calculated specifically for crochet; the supplied knitting graphic is visual reference only.
How much ease should I add?
Start with 1–2 inches for everyday layering, then consider yarn drape and garment style.
Can I use the chart without swatching?
No. The conversion depends on your washed stitches and rows per inch.
Conclusion
The finished project combines measured shaping, readable colorwork and practical finishing in one complete original crochet construction. Compare the finished measurements with the plan, confirm that every seam and carried strand is secure, and follow the yarn label for washing and storage.
