Size Charts

Find your swimwear size by brand

Choose a brand-specific size chart below to compare your measurements before buying swimwear, a racing suit or triathlon gear. Size labels and fit can vary between brands and garment types, so use the chart for the product you are considering rather than relying on your usual clothing size alone.

How to measure for swimwear

Use a flexible measuring tape and keep it level, snug but not tight. Compare your measurements with the relevant brand chart, checking the units shown.

• Chest or bust: measure around the fullest part.
• Waist: measure around your natural waistline.
• Hips: measure around the fullest part.
• Height and weight: check these where the chart uses a height-and-weight grid.
• Other measurements: follow the brand's instructions for any additional measurements shown.

Swimwear sizing FAQ

Do swimwear brands size differently?

Yes. Brands can use different size systems and cuts. Check the specific brand and garment chart, including whether the labels are Australian, US, European or letter sizes.

Can I use a training swimsuit chart for a racing suit?

Use the dedicated racing chart where one is provided. Racing and technical suits have a different fit from training swimwear, so the same size label may not give the same fit.

Should I automatically size down for a racing suit?

No. Start with your measurements and the brand's racing size chart rather than automatically choosing a smaller size. Check the specific model's fitting guidance before ordering.

What if my measurements fall between sizes?

Check the product's fit details and any brand guidance. If your measurements suggest different sizes, ask the Swimwear Shack team for help with the specific product rather than automatically sizing up or down.
