Most fit problems with training clothes come from guessing a size rather than measuring for one. It takes five minutes, a soft tape measure and, ideally, someone to help. Here is how to do it properly.
Before you start
Use a soft cloth or plastic tape, not a metal one. Measure over underwear or a thin layer, never over a hoodie or jeans. Stand relaxed with your feet together, and look straight ahead rather than down at the tape, because bending your head changes the reading.
Write each number down in inches or centimeters. Our size guide has both.
The four measurements
Chest or bust. Wrap the tape around the fullest part of your chest, under your arms and across your shoulder blades. Check in a mirror that it is level at the back. Breathe out normally, then read it.
Waist. Find your natural waist, the narrowest part of your torso, usually an inch or so above your belly button. Do not pull your stomach in. You will be wearing the clothes while breathing normally, so measure that way.
Hip. With your feet together, measure around the fullest part of your seat. Move the tape up and down a little to find the widest point.
Inseam. This one is easiest with a pair of pants that already fit you well. Lay them flat and measure along the inside leg, from the crotch seam to the hem. Measuring your own leg directly is harder to get right.
Common mistakes
- Pulling the tape tight. It should sit flat against your skin without pressing in. If it leaves a mark, it is too tight.
- Measuring at the end of the day after a big meal. Your waist can vary by an inch across a day. Morning is most consistent.
- Letting the tape drop at the back. This adds an inch or two to chest and hip. Use a mirror or ask for help.
- Using your jeans size. Jeans sizes vary between brands and are often not your actual waist measurement.
When you land between sizes
Check the fit of the piece. For Compression pieces like leggings and sports bras, go by your hip or bust and size down for a firmer hold. For Regular fits, size up if you layer. For Relaxed fits, if you are between sizes, take the smaller one.
