Size chart
This size guide covers Arena Women's Swimwear, sized by body measurements across a wide range from international size 32 through to 54. Arena sizes women's swimwear by height, chest, breast, waist, and hip circumference. For the most accurate fit, always measure rather than relying on clothing size alone. International and Australian sizes are shown as numeric sizes.

International and AUS sizes are numeric. UK sizes are even numbers. Always measure rather than relying on clothing size alone — Arena swimwear is sized to body measurements. If measurements fall between two sizes, speak to a member of staff at Allens for guidance.
Measure your height, chest, breast, waist, and hips in centimetres and match these to the size table above. Always use body measurements rather than clothing size, as Arena sizing is based on body dimensions. If your measurements fall between two sizes, speak to a member of staff at Allens for advice on the best fit for the specific style you are interested in.
The chest measurement (B) is taken around the body under the armpits — this reflects the frame of the torso. The breast measurement (C) is taken around the fullest part of the bust. Arena uses both measurements to ensure a swimsuit fits correctly across the whole upper body. If the two measurements suggest different sizes, prioritise the breast measurement for one-piece swimsuits.
Use a soft tape measure taken directly against the skin or over light underwear. Measure height standing straight against a wall, chest under the armpits, breast around the fullest part of the bust, waist around the narrowest point, and hips around the fullest part of the seat. Record all measurements in centimetres and use the size table above to find the best fit.
Arena women's swimwear in this range covers international sizes 32 to 54, corresponding to UK sizes 26 to 48. This covers a wide range of body measurements from a chest circumference of 70cm through to 125cm. If you are outside this range or need guidance on a specific style, please contact our team at Allens.
Arena is a leading competitive swimwear brand and their women's swimwear is well suited to training and club swimming. This size guide covers Arena's training swimwear range, which is made from higher chlorine-resistant fabric designed to withstand regular pool use. Arena also produces a separate range of FINA-approved competition suits for racing — if you are looking for a race suit specifically, please contact our team for guidance.
Arena's international sizing (France/International) uses even numbers from 32 upwards. UK sizing runs from 26 to 48. Australian sizing starts at 12–13 for the smallest size before moving to standard even numbers. All sizes correspond to the same body measurements — only the labelling differs. Use the body measurement rows in the size table to find the right size regardless of region.
Rinse the swimwear thoroughly in cold fresh water immediately after every swim to remove chlorine and salt. Allow to dry naturally away from direct sunlight — do not tumble dry or wring out the fabric. Avoid sitting on rough pool surrounds as this can damage the fabric. With proper care, Arena's chlorine-resistant fabric will maintain its shape, colour, and performance properties for longer.
If your measurements fall between two sizes, we recommend contacting our team at Allens for advice. The best size will depend on the specific style — some styles have more stretch or coverage than others. Our team can advise based on the swimwear you are interested in. You can reach us via the contact page or by calling +44 1827 330600.
