Understanding 50C Bra Size
A 50C bra size is considered a large band size with a full cup size. This size is perfect for people with a fuller frame and fuller breast volume. Let's explore what makes this size unique and how to find the perfect fit.
Is 50C considered big or small?
Fast facts about 50C
- Snug 50 band with a 3-inch cup jump.
- Standing bust around 52.5–53.5 in keeps the cup filled.
- Share cup volume with 48D, 52B for band tweaks.
- Always scoop-and-swoop and check the gore for a flat anchor.
How 50C is measured
Band fit
Aim for a snug 48.5–49.5 in underbust so the 50 band stays level without digging.
Cup depth
Standing bust in the 52.5–53.5 in range keeps roughly a 3-inch cup difference.
Support focus
Choose firm wings, fully adjustable straps, and swap sister sizes if the band shifts during wear.
50C bust size in inches
| Measurement | Typical inches | How to capture it |
|---|---|---|
| Snug band (ribcage) | 48.5–49.5 in | Measure firmly under the bust on an exhale, then round to the band label. |
| Standing bust | 52.5–53.5 in | Keep the tape level across the fullest point while standing tall. |
| Band-to-bust difference | ≈3 in | Subtract your snug band from the standing bust to confirm cup depth. |
| Approx. cup depth | 4.5–5.5 in | Measure from the underwire root to the apex on a well-fitting bra. |
50C bust size in centimeters
| Measurement | Typical cm | How to capture it |
|---|---|---|
| Snug band (ribcage) | 123.2–125.7 cm | Measure firmly beneath the bust, then map it to EU/FR/JP band labels. |
| Standing bust | 133.4–135.9 cm | Keep the tape level across the fullest point without compressing tissue. |
| Band-to-bust difference | ≈7.6 cm | Use the difference to double-check your metric cup depth. |
| Approx. cup depth | 11.4–14 cm | Trace from underbust to apex on a supportive bra to check projection. |
- Uses a wider band to distribute support across a fuller torso, which can make cups appear more proportionate.
- Adds more projection than A-B cups, particularly noticeable on narrow bands.
- Monitor posture and band tension—small shifts change how the size looks.
- Try sister sizes 48D, 52B to fine-tune band tension.

- Try 52B when you need tighter or looser band support.
Fit checks before you buy
When trying on 50C bras, look for these key fit indicators:
- 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.
