Your band should stay level
If it rides up at the back, try a smaller band or adjust your straps.

Gapping or spillage can mean cup volume is not quite right.

You should feel supported, never restricted, poked or pressured.
How to measure bra size at home
Finding a bra size starts with two measurements: your underbust and your fullest bust. The underbust estimates band size, while the difference helps estimate cup volume. Use this calculator as a starting point, then check that the band feels secure and cups sit smoothly.
FEMBRA offers wire-free, non-padded bras in 32B, 34B, 36B, 38B, 40B and 42B. If your result is close to another cup letter, message our fit help for the closest comfortable option.
Quick measurement tips
- Use a flexible tape, not a loose string.
- Keep the tape parallel to the floor.
- Measure without thick padding.
- Do not hold your breath or pull too tightly.
Frequently asked questions
How do I calculate bra cup size in centimetres?
Subtract underbust from fullest bust. The difference estimates cup volume; the tool does this automatically.
What if my exact result is unavailable?
Use the suggested band as a starting point and ask FEMBRA on WhatsApp for help selecting the closest available fit.
Should I measure in centimetres or inches?
Either works. Centimetres are usually easier for Pakistani size charts; the tool converts inches automatically.
