CNFans UK sizing tool
CNFans Size Recommender
Add your measurements and preferred fit for an approximate starting point across M–XXL men’s clothing. The estimate uses body chest first, with height and weight as secondary references. Treat it as a starting reference, not a promise of fit.

Measure your body chest, rather than using a garment measurement. The figures below are general references; individual product measurements should take priority when available.
Your measurements stay in this page while you use the tool. No recommendation is shown until all fields are complete.
General Chinese Menswear Reference
These are approximate general reference measurements; individual garments and cuts can differ. Garment chest is the full circumference of a finished garment; flat chest is the width measured across the garment under the arms.
On a small screen, scroll the table horizontally to compare all measurements.
| Size | Chinese reference | Garment chest | Flat chest | Shoulder | Length | Sleeve | Height | Weight |
|---|---|---|---|---|---|---|---|---|
| M | 170/88A | 106 cm (104–108 cm) | 53 cm | 44–46 cm | 67–70 cm | 61–64 cm | 165–175 cm | 55–65 kg |
| L | 175/92A | 110 cm (108–112 cm) | 55 cm | 45–47 cm | 69–72 cm | 62–65 cm | 170–180 cm | 62.5–72.5 kg |
| XL | 180/96A | 114 cm (112–116 cm) | 57 cm | 46–49 cm | 71–74 cm | 63–66 cm | 175–185 cm | 70–80 kg |
| XXL | 185/100A | 118 cm (116–120 cm) | 59 cm | 47–50 cm | 73–76 cm | 64–68 cm | 180–190 cm | 77.5–90 kg |
How the recommendation works
Your body chest measurement is the primary input. The tool adds 8 cm for a slim fit, 12 cm for regular or 16 cm for relaxed, then starts with the smallest available garment chest that meets that target. Height and weight are secondary checks and can move the result up by no more than one size when both point higher. They will not lower a size required by the chest calculation.
If your target is above the XXL reference, the tool shows XXL as the closest available size and advises checking the item measurements. When height, weight and chest suggest different ranges, the result is marked low confidence rather than presented as exact.
Check the individual style
Different brands and styles can fit differently. Puffer jackets, down jackets, oversized cuts and drop-shoulder pieces may measure larger than this general reference. Always compare the product’s own measurements when they are available.
