arena Size Chart
The following sizing information is based on the current official arena Size Guide. arena often uses French sizing as the displayed product size for swimwear, so international and German equivalents are shown together with body measurements.

Kids – Current arena Size Ranges
The current arena online shop primarily lists children's swimwear by age. The current central Size Guide does not publish a separate static body-measurement chart for kids, so no unsupported body measurements are added here.
| Product category | Current sizes / age ranges | Note |
| Kids' swimwear | 1–2 / 2–3 / 4–5 / 6–7 / 8–9 / 10–11 / 12–13 / 14–15 years | Only some of these sizes may be available for a given product. |
| Baby swimwear | 6M / 12M / 18M / 24M | Model-dependent |
| Junior race suits / Powerskin | product-dependent, e.g. 28 / 30 / 32 / 34 / 36 | Always use the product-specific size chart for racing products. |
Swim Caps and Swim Goggles
| Product category | arena sizing | Guide |
| Many adult swim caps | One Size Fits All | One size |
| Junior swim caps | Age 6–12 | approx. 6–12 years |
| Kids' swim caps | Age 2–5 | approx. 2–5 years |
| Many adult swim goggles | One Size Fits All | One size with adjustable strap |
| Junior swim goggles | Age 6–12 | approx. 6–12 years |
| Kids' goggles / masks | Age 2–5 | approx. 2–5 years |
How to Take Body Measurements
- Height: stand straight and measure from the crown of the head to the sole of the foot.
- Chest / bust: measure around the fullest part.
- Under bust: measure around the rib cage directly below the bust.
- Waist: measure around the narrowest part of the waistline.
- Hips: measure around the fullest part of the hips.
- Torso loop: measure from the highest point of the shoulder, through the crotch and back to the starting point.
Important: Powerskin and other racing suits are designed to fit much tighter than training swimwear. Model-specific fit guidance takes priority. If the individual arena product has a different size chart, always use that product-specific information.
