Choosing the right size is one of the most important steps before you cast on a sweater. This sweater size chart for knitting gives you easy-to-compare XS–XL measurements in centimeters and inches, plus practical advice on measuring, ease, gauge, and fit.
Whether you're knitting your first pullover or planning a handmade sweater for someone else, understanding the difference between body measurements and finished garment measurements can help you achieve a more comfortable fit.
Important: The chart below is an illustrative finished-garment size guide for a relatively straight adult sweater. It is not a universal women's, men's, or unisex sizing standard. Always follow the measurements and schematic supplied with your knitting pattern when available.
Sweater Size Chart: XS–XL in CM and Inches
The following chart provides example finished-sweater measurements for five sizes. Chest circumference refers to the complete garment, while flat chest width is measured across the sweater when laid flat.
| Size | Finished Chest Circumference | Chest Width (Flat) | Body Length | Sleeve Length* |
|---|---|---|---|---|
| XS | 84–88 cm 33.1–34.6 in |
42–44 cm 16.5–17.3 in |
58 cm 22.8 in |
60 cm 23.6 in |
| S | 88–92 cm 34.6–36.2 in |
44–46 cm 17.3–18.1 in |
60 cm 23.6 in |
61 cm 24.0 in |
| M | 96–100 cm 37.8–39.4 in |
48–50 cm 18.9–19.7 in |
62 cm 24.4 in |
62 cm 24.4 in |
| L | 104–108 cm 40.9–42.5 in |
52–54 cm 20.5–21.3 in |
64 cm 25.2 in |
63 cm 24.8 in |
| XL | 112–116 cm 44.1–45.7 in |
56–58 cm 22.0–22.8 in |
66 cm 26.0 in |
64 cm 25.2 in |
*Sleeve length: Measured approximately from the shoulder seam to the cuff for a set-in-sleeve sweater. Raglan, drop-shoulder, and top-down patterns may use different measurement points.
Body and sleeve lengths are illustrative design targets, not universal size requirements. Inch measurements are rounded to one decimal place.
How to Measure a Knitted Sweater
Accurate measurements help you compare your knitting project with a sweater you already own and love. Place the sweater on a flat surface without stretching the fabric before measuring.
1. Finished Chest Circumference
Lay the sweater flat without stretching. Measure straight across the body just below the armholes and multiply by two.
For example, a flat width of 50 cm (19.7 in) gives approximately 100 cm (39.4 in) finished chest circumference.
2. Body Length
Measure from the highest point of the shoulder near the neckline down to the lower hem.
Cropped, tunic, and oversized sweaters may deliberately differ from the lengths shown in the chart.
3. Sleeve Length
For a set-in sleeve, measure from the shoulder seam to the cuff. For raglan or drop-shoulder designs, check the pattern schematic carefully because shoulder construction changes how sleeve length is defined.
Body Measurements vs. Finished Sweater Measurements
Your body bust or chest measurement is the circumference around your torso at the fullest point.
The finished sweater chest measurement is the circumference of the completed garment.
The difference between these two measurements is called ease.
For example, a sweater that measures 100 cm (39.4 in) around the chest is not necessarily intended for someone whose body chest is 100 cm. The designer may have included extra room for comfort or a relaxed silhouette.
How Much Ease Should You Add?
Positive ease is the extra space between your body measurement and the finished sweater measurement. The amount depends on the style you want.
| Fit Style | Illustrative Positive Ease |
|---|---|
| Close-fitting | 0–4 cm / 0–1.6 in |
| Regular | 4–8 cm / 1.6–3.1 in |
| Relaxed | 8–12 cm / 3.1–4.7 in |
| Oversized | 12–20 cm / 4.7–7.9 in |
These are examples, not rigid rules. Some fitted knitting patterns use negative ease, especially with stretchy fabrics. Follow the designer's intended fit whenever possible.
Example: Choosing Your Sweater Size
Suppose your body chest measures 92 cm (36.2 in) and you want approximately 6 cm (2.4 in) of positive ease.
Your target finished chest measurement would be:
92 cm + 6 cm = 98 cm
That's approximately 38.6 inches.
In our illustrative size chart, 98 cm falls within the Medium (M) finished-chest range of 96–100 cm (37.8–39.4 in).
Next, compare the body length and sleeve length with your preferences. You may need to adjust these measurements even when the chest size is correct.
Check Your Knitting Gauge Before Casting On
Gauge determines whether your sweater comes out as planned. Even a small difference in stitch tension can affect the finished garment size.
Before beginning your sweater, knit a gauge swatch using the yarn, needles, and stitch pattern specified in your instructions.
- Knit a swatch larger than the measurement area.
- Wash and dry it as you plan to treat the finished garment.
- Measure stitches and rows across a central 10 cm (4 in) area.
- Compare your results with the pattern's required gauge.
- Adjust needle size or technique if necessary, then swatch again.
If your stitch gauge differs from the pattern, the finished chest circumference may change even when you follow the correct stitch count.
Are US, UK and EU Sweater Sizes the Same?
No. XS, S, M, L, and XL labels are not consistently defined across designers, clothing brands, or countries.
Numeric clothing-size conversions also vary, which makes international sizing particularly confusing for knitters.
For a global knitting audience, actual body measurements and finished-garment measurements in centimeters and inches are more reliable than a size label alone.
Always compare your measurements with the pattern's finished-size chart rather than relying entirely on familiar clothing sizes.
Frequently Asked Questions
Should I choose my sweater size by bust measurement?
Start with your body chest or bust circumference, then add or subtract the ease intended by the pattern. Compare the result with the finished-garment measurements.
Is chest width the same as chest circumference?
No. Flat chest width is measured across the sweater when laid flat. Chest circumference is approximately twice that number.
What if I fall between two sizes?
Consider your preferred ease, fabric stretch, and the pattern's finished measurements rather than automatically sizing up. You may also be able to adjust the body or sleeve length independently.
Can I use this chart for men's and children's sweaters?
This is an illustrative adult sweater reference, not a universal grading system. Men's, children's, and specialized garment patterns require their own sizing and proportions.
Should I measure in centimeters or inches?
Either unit works. Use whichever you find most comfortable, but stay consistent throughout your project. This chart provides both centimeters and inches to help knitters around the world compare measurements easily.
Final Tips for a Better Sweater Fit
Choosing the right sweater size doesn't have to be complicated. Start by measuring your body, decide how much ease you want, and compare your results with the pattern's finished-garment measurements.
Always check your gauge and review the sweater schematic before casting on. A little preparation can make a big difference in how your handmade sweater looks and feels.
Keep this sweater size chart for knitting handy as a quick reference whenever you begin a new pullover or cardigan project.
