Learn how to measure for a sports bra correctly here.
Sports Bras usually fit slightly tighter than your normal bras, but your size is usually going to be the same. Don’t size down!
Remember that your bra size will change several times during your life – hormones, raging, pregnancy and weight loss or gain can all have an effect. So even if you think you’re confident with your bra size double-check to be sure!
Use a soft table measure, and if possible measure without wearing a bra.
Find your Rib Cage Measurement
Measure around your rib cage just under your bust. Round down to the closest inch. This is your rib cage measurement.
Find your Band Size
Take your rib cage measurement and find your band size in the chart below:
| RIB CAGE MEASUREMENT | BAND SIZE |
| 25 – 27 INCHES | 30 |
| 27 – 29 INCHES | 32 |
| 29 – 31 INCHES | 34 |
| 31 – 33 INCHES | 36 |
| 33 – 35 INCHES | 38 |
| 35 – 37 INCHES | 40 |
| 37 – 39 INCHES | 42 |
| 39 – 41 INCHES | 44 |
Find your Cup Size
Measure around the fullest part of your bust and round up to the nearest whole number to find your bust measurement.
Finally, subtract your rib cage measurement from your bust measurement. The difference in inches is your cup size. Between sizes? Just round up!
| BUST SIZE LESS RIB CAGE SIZE | CUP SIZE |
| 3 INCHES | AA |
| 4 INCHES | A |
| 5 INCHES | B |
| 6 INCHES | C |
| 7 INCHES | D |
| 8 INCHES | DD |
| 9 INCHES | E |
| 10 INCHES | F |
Your sports bra should feel a little snugger than your normal bra, but you should be able to breathe deeply and easily!
- Make sure the band sits firmly around your ribs – you should be able to fit two fingers snugly between your body and the band. If the band rides up or isn’t live when you raise your arms it’s too big!
- Straps should feel secure, comfortable and not too tight. Again use the two-finger rule!
- If your sports bra has cups your boobs should be centred, contained and secure in these, without gaps or wrinkles in the fabric. Your bust should feel secure and supported when you move.
