How to measure bra size? A complete guide
How to measure bra size? Wearing a bra with the right size is very significant for every woman. The wrong size might cause not only discomfort but also bad posture, shoulder pain, and changes in body shape. Amazingly, more than 70% of women wear the wrong size.
The good news is that you can easily measure your bra size from home. Let’s understand it step by step.
Why is the right bra size important?
wrong size → shoulder pain
Cup leakage or empty spaces
❌ No support if the band is loose
✔️ Correct size → All-day comfort
Great fit in clothes
✔️ Proper support and good posture
Easy Way to Measure Bra Size
You need two measurements to measure your bra size:
Band Size (Underbust)
Bust Size (Overbust)
Ok, let’s get started.
Step 1: Measure the Band Size
Take a soft measuring tape and wrap it around the lower part of your breast.
✔️ Things to note:
The tape must be tight and straight.
Peerless to the ground
Measure over a non-padded bra or without a bra
How to calculate band size?
Many brands in India follow the “size equals band” system.
Or general formula:
If size is loose, add 4 inches
If the size is loose, add 5 inches
Example:
Underbust = 31 inches
31 + 5 = 36 → Band size = 36
Step 2: Bust Measurement
Place the measuring tape on the fullest part of your breast, nipple level.
Tips:
The measuring tape should not be too loose or tight.
Stay straight and even
Do not raise your arms, stand normally.
Step 3: Find your cup size
Cup Size = Bust – Band
You can determine your cup size from the following chart:
Difference (inches) Cup Size 1 A 2 B 3 C 4 D 5 DD / E 6 F 7 G
Example:
Band = 34
Bust = 37
Difference = 37 – 34 = 3 Cup Size = C Final Bra Size = 34C
Signs of the wrong bra size
❌ If the bra is small:
The straps are pinched in the shoulders.
Coming out of the cups
The space between the breasts does not touch the chest.
❌ If the bra is large,
There is air inside the cups.
The band rides up
You have to adjust it throughout the day
✔️ If the size is right:
The band fits snug.
It covers the cup completely.
The straps do not hurt the shoulders.
A comfortable experience all day
Tips on Selecting the Right Bra
- Two-Finger Test
Your two fingers can easily go under the band.
- Wear it on a medium hook
This way you can adjust the band that loosens over time.
- The center gore should touch the chest
If it does not, the size is wrong.
- Wide straps are better for heavy busts
- Replace bras every 6–12 months
Fabric and elastic loosen too fast.
