How to Measure For Sports Bra
- Band size: Wrap a soft tape measure snugly around the ribcage, directly under the bust. Keep it level all the way round. Note the number in inches or centimetres.
- Bust size: Measure around the fullest part of the bust, keeping the tape relaxed but not loose.
- Compare: Use those two numbers against our sports bra size chart on this page to identify your size. Between sizes? Start with the larger band or cup for comfort, then adjust.
Tips for the Perfect Fit Guide
- If your child’s size falls between two options, it’s usually best to go for the larger one. That way, there’s room to grow during those quick adolescent growth spurts.
- Fabrics that stretch, like a soft cotton-spandex mix, are great because they move with your child and keep them comfy all day long.
- When choosing a sports bra, look for one with double layers, it gives extra support and feels nicer next to the skin.
- Don’t forget to check the size chart before buying . At Plan B, you will always find a sports bra that fits just right for your child’s needs.

Sports Bra FAQs
How accurate is the sports bra size chart for teenagers or first-time wearers?
It’s a reliable starting point when you measure chest and underbust correctly. If between sizes, size up for comfort. Ensure that the bust measurement is the right size so that the breast remains firm.
Is a training bra the same as a sports bra? What is the difference
No. A training bra offers light coverage for beginners, while the feature of a sports bra is to provide added support for activity.
How do age and size decide between a regular sports bra and a padded sports bra?
Prioritise measurements over age. Choose padded styles if modesty or shape is preferred; otherwise, a regular sports bra with good support works well.
