It’s that simple! But let’s break it down further to ensure you get the most accurate results.
Measuring Your Band Size
- Wrap a soft measuring tape snugly around your ribcage, just under your breasts.
- Make sure the tape is level and parallel to the ground.
- Round to the nearest whole number (in inches).
Measuring Your Bust Size
- Wrap the measuring tape around the fullest part of your breasts.
- Ensure the tape is not too tight and is parallel to the ground.
- Round to the nearest whole number (in inches).
Understanding Bra Sizes
Bra sizes consist of two parts:
- Band Size: The number (e.g., 32, 34, 36)
- Cup Size: The letter (e.g., A, B, C, D)
For example, a bra size of 34C means a 34-inch band size with a C cup.
Cup Size Calculation
The cup size is determined by the difference between your bust and band measurements:
- 0-1 inch difference: AA
- 1 inch: A
- 2 inches: B
- 3 inches: C
- 4 inches: D
- 5 inches: DD/E
And so on. Remember, cup sizes can vary by brand, so always try on bras for the best fit.
Signs You’re Wearing the Wrong Bra Size
- Straps digging into your shoulders
- Band riding up in the back
- Cups that gape or overflow
- Underwire poking or not sitting flat against your chest
If you experience any of these issues, it’s time to remeasure and find your true size.
Tips for a Perfect Fit
- Try on multiple sizes: Your size can vary between brands.
- Adjust the straps: They should be snug but not tight.
- Check the band: It should be level all the way around.
- Scoop and swoop: Lean forward and scoop your breast tissue into the cups.
- Test the fit: Raise your arms; the bra shouldn’t move.

Frequently Asked Questions
How often should I measure my bra size?
It’s recommended to measure your bra size every 6-12 months, or if you experience significant weight changes, pregnancy, or hormonal shifts.
Can I measure myself for a bra?
Yes, you can measure yourself, but for the most accurate results, consider getting professionally fitted at a lingerie store.
Why is my bra size different in different brands?
Bra sizes can vary between brands due to different sizing standards and manufacturing processes. Always try on bras or check the brand’s specific size chart.
How do I know if my bra fits correctly?
A well-fitting bra should be comfortable, supportive, and not cause any bulging, gaping, or digging. The band should be snug on the loosest hook and parallel to the ground.
What if I’m between sizes?
If you’re between sizes, it’s generally better to go up in the band size and down in the cup size, or vice versa. For example, if 34C is too small in the cup but 34D is too big, try 36C.
