Arena’s junior jammer chart, read from Arena’s own chart image. Each measurement is read in the chart on its own; GearIQ shows the sizes they all allow, or — if they disagree — every size any of them allows, at Medium. Gaps inside the printed ranges are kept; a value in a gap matches no size there.
What we’ll ask
- Waist
- Hips
Arena’s chart is in centimetres, so enter each measurement in cm.
Based on Arena's official race-suit size guide (arenasport.com, captured Oct 26, 2026). Values used exactly as printed.
