How 36B is measured
Band fit
Aim for a snug 34.5–35.5 in underbust so the 36 band stays level without digging.
Cup depth
Standing bust in the 37.5–38.5 in range keeps roughly a 2-inch cup difference.
Support focus
Choose firm wings, fully adjustable straps, and swap sister sizes if the band shifts during wear.
36B bust size in inches
| Measurement | Typical inches | How to capture it |
|---|---|---|
| Snug band (ribcage) | 34.5–35.5 in | Measure firmly under the bust on an exhale, then round to the band label. |
| Standing bust | 37.5–38.5 in | Keep the tape level across the fullest point while standing tall. |
| Band-to-bust difference | ≈2 in | Subtract your snug band from the standing bust to confirm cup depth. |
| Approx. cup depth | 3.5–4.5 in | Measure from the underwire root to the apex on a well-fitting bra. |
36B bust size in centimeters
| Measurement | Typical cm | How to capture it |
|---|---|---|
| Snug band (ribcage) | 87.6–90.2 cm | Measure firmly beneath the bust, then map it to EU/FR/JP band labels. |

| Band-to-bust difference | ≈5.1 cm | Use the difference to double-check your metric cup depth. |

- The band should fit snugly around your ribcage
- Cups should fully contain your breasts without spillage
- Straps should stay in place without digging in
- The center gore should lie flat against your chest
- Keep the band parallel to the floor on the middle hook.
- Scoop and swoop tissue into the cups before checking the gore.
- Adjust straps for lift, then reassess comfort after an hour of wear.
Remember that fit can vary between brands and styles. Always try on bras before purchasing to ensure the perfect fit.
