How to Measure Your Bra Size at Home (Yes, It’s Easier Than You Think!)
Let’s be honest: wearing the wrong bra size is more common than most women realize. If your straps are slipping, your band feels too tight, or you’re constantly adjusting throughout the day, your bra might be working against you instead of for you.
The truth? Nearly 80% of women are wearing the wrong bra size.
Knowing your correct size can make a world of difference in your posture, comfort, and confidence, especially if you deal with breast tenderness, hormonal fluctuations, or postpartum changes. And the best part? You don’t have to leave your house to figure it out.
Why It Matters
Wearing the right bra size isn’t just about looks, it’s about supporting breast health and your everyday comfort. Ill-fitting bras can contribute to:
Back and shoulder pain
Skin irritation or redness
Poor posture
Breast tissue damage over time
Whether you’re prepping for pregnancy, navigating postpartum changes, or simply want a better everyday fit, getting your size right is a small act of self-care with big benefits.
What You’ll Need
To measure at home, you’ll only need:
A soft measuring tape
A mirror
A well-fitting (non-padded) bra or no bra
A notepad or phone to write down measurements
Step 1: Measure Your Band Size
Stand in front of a mirror with your measuring tape.
Wrap the tape snugly around your ribcage, directly under your bust (where your bra band sits).
Make sure the tape is level all the way around.
Round to the nearest whole number.
If it’s even, add 4 inches.
If it’s odd, add 5 inches.
This is your band size.
Example: If you measured 31 inches → 31 + 5 = 36 band size.
Step 2: Measure Your Bust
Now measure around the fullest part of your bust, usually across your nipples.
Make sure the tape is straight and not too tight or loose.
Round to the nearest whole number.
Step 3: Calculate Your Cup Size
Take your bust measurement and subtract your band measurement:
Bust - Band = Cup Size
Use this chart to find your cup size:
1 inch = A
2 inches = B
3 inches = C
4 inches = D
5 inches = DD or E
6 inches = DDD or F
Example: Bust = 39 inches, Band = 36 → 39 - 36 = 3 = C cup.
Your bra size is 36C.

Still Not Fitting Right?
If your bra size seems correct but still doesn’t feel good:
Try different brands or styles (not all sizing is universal).
Look for sister sizes (ex: 34C → 36B or 32D).
Avoid padded bras when measuring.
And remember, your body changes! Hormones, weight shifts, pregnancy, and even stress can impact your breast size. It’s a good idea to re-measure every 6–12 months.
