How to measure your bra size

A woman measuring her bra band size.
  • You’ll need a flexible tape measure. It’s also best to wear a bra that doesn’t change your shape — no padding or compression. You can also just skip the bra.

  • Measure around your rib cage where the bottom band would sit. The tape measure should feel quite snug. If you get a fraction, round down to the nearest inch. Using , find your corresponding band size based on your measurement.

  • Measure around the fullest part of your boobs — which may not be the center — and round up to the nearest inch. Then subtract your rib cage measurement. The difference in inches is your suggested cup size. If you get a fraction, round up to the larger size.


How we solved six common bra issues.

Skip the on/off struggle

Changing into your run bra should be easy. If pullover bras don’t work for you, try styles with adjustable back closures, or even zip-front designs.

Stop straps from chafing

Chafing is the worst. Try adjustable straps to fine-tune the fit, or free-cut finishing which practically eliminates edges on straps.

Improve bra breathability

Get rid of boob sweat for good with styles that include mesh paneling, perforated cups, or strappy styles that minimize coverage.

No more nipping out

Stay confident in your coverage with styles that feature built-in molded cups or removable cups.

Smooth out pesky seams

Bras with nearly seamless finishing or bonded finishing — a fancy way of saying seams are adhered with heat instead of stitched — help eliminate seam-on-skin irritation.

Prevent bottom band chafing

Again, chafing is the worst. Our innovative hidden bottom band acts like second skin to reduce irritation, while adjustable bottom bands can fine-tune your fit to make sure the band won’t move.
