Learn how to measure your bra size correctly and find a push-up bra that fits well, feels comfortable, and gives the lift you want.
Quick answer
To choose the right push-up bra size, measure your band and bust with a soft tape, then use the difference to find your cup size. Always try the bra with the adjustable straps and check that the center gore lies flat.
Why push-up bras fit differently
Push-up bras often have extra padding or angled cups that can make the same size feel different from a standard bra. The padding lifts tissue upward, so the cup shape and depth matter more than the letter alone.
If you are between sizes, the band is the best place to adjust. A snugger band gives more lift, while a looser band can let the cups gap. Choose the size that feels secure on the loosest hook when new.
Trade-offs to keep in mind
A push-up bra can create a fuller look, but it may not suit every top or occasion. For low-cut necklines, a plunge style works better, while a balconette push-up gives a rounder shape under higher necklines.
Comfort matters too. If the underwire digs or the straps slip, the size or style may be wrong even if the measurement seems correct. Consider the shape of your ribcage and breast tissue, not just the tape measure.
Decision rules for your push-up bra size
- Measure your band: Wrap the tape snugly around your ribcage, just under your bust. Round to the nearest even number. This is your band size. If the band rides up in the back, try a smaller band size.
- Measure your bust: Wrap the tape around the fullest part of your chest, keeping it level. Subtract your band measurement from this number. The difference in inches (1, 2, 3...) corresponds to A, B, C cups and so on.
- Check the fit in the mirror: The center gore should lie flat against your sternum, the underwire should surround your breast tissue without digging, and the straps should stay in place without slipping. If the cups gap or spill, try a different cup size, not just a tighter band.
