Easy Bra Fit Guide: How Do I Find My Correct Bra Size?
Finding a bra that fits just right can be a total game-changer—boosting your confidence, comfort, and posture all in one. Yet, so many of us are wearing the wrong size without even knowing it. Whether you're shopping for your first bra, doing a drawer refresh, or finally treating yourself to lingerie that actually fits, this simple guide will walk you through everything you need to know to get your perfect bra size—right from home.
Step 1: Measure Your Band Size
What you need: A soft measuring tape & a mirror
-
Stand braless or wear a non-padded bra.
-
Wrap the tape snugly around your ribcage, just under your bust.
-
Make sure it’s straight across your back.
-
Round to the nearest whole number:
-
If even, add 4 inches
-
If odd, add 5 inches
-
That’s your band size (example: 31” + 5 = 36 band)
-
Step 2: Measure Your Bust Size
-
Wrap the tape around the fullest part of your bust (over the nipples).
-
Keep it gently snug—not tight.
-
Round to the nearest whole number.
-
That’s your bust measurement.
Step 3: Find Your Cup Size
Bust measurement - Band size = Cup size number
Use the difference to find your cup:
| Difference (inches) | Cup Size |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
| 6 | DDD/F |
Example: Bust 38" – Band 34" = 4 → Cup Size: D
Bra Size: 34D
Fit Check Tips
-
Band should lie level all around. It gives 80% of the support.
-
Cups should fully hold your breasts—no spillage or gaping.
-
Straps should feel secure, not dig in.
-
You should be able to fit 2 fingers under the band and straps.
