Measure around the fullest part of your breasts.
Measurement tip:
Keep the measuring tape level around your body. It should
be comfortably snug for the underbust and relaxed enough
around the fullest bust area without compressing tissue.
For better consistency, measure twice.

Your calculated size is only a starting point. Different brands, styles and breast shapes can affect how a bra fits. Check these points when trying on a bra.
✓ Band stays level
The band should sit reasonably level around your body
rather than riding upward at the back.
✓ Cups contain the breast tissue
Look for obvious spilling over the cup edge or sides.
The cup should feel comfortable without excessive pressure.
✓ Underwire sits around the breast
If the bra has an underwire, it should sit around
the breast rather than directly on breast tissue.
✓ Check for excessive gaping
Significant empty space may indicate that the cup size
or cup shape isn’t suitable for that particular bra.
✓ Move and test
Raise your arms, bend and sit down. The bra should
remain comfortable and reasonably stay in place.
Important:
Bra sizing varies between brands, styles and countries.
This calculator provides an estimated starting size and
cannot guarantee that every bra in that size will fit.
