Wearing the right bra size is essential not only for comfort but also for posture, appearance, and confidence. Yet, research shows that over 80% of women wear the wrong bra size. If your bra is digging into your shoulders, gaping at the cups, or riding up your back, it’s time to measure yourself properly.
In this detailed guide from SUNDORIKA, one of Bangladesh’s leading online shopping destinations for women’s products, we’ll teach you exactly how to measure bra cup size at home, explain what the numbers and letters mean, and help you find your perfect fit for every occasion.
🌸 Why Knowing Your Bra Size Is So Important
Wearing the right bra is not just about looks—it’s about health, posture, and confidence.
Benefits of Wearing the Right Bra:
- ✅ Better posture and spine support
- ✅ Enhanced body shape and silhouette
- ✅ Reduced back and shoulder pain
- ✅ Improved comfort and movement
- ✅ Boosted confidence and self-esteem
Whether you’re wearing a push-up bra, sports bra, lace bralette, or strapless bra, getting the size right makes all the difference.
👙 The Basics: Understanding Bra Sizes
Bra sizes are made up of two main parts:
- Band Size (the number) – e.g., 32, 34, 36
- Cup Size (the letter) – e.g., A, B, C, D
So a bra size like 34B means:
- 34: the band measurement (under the bust)
- B: the cup size (based on bust fullness)
To know your perfect size, you need two accurate measurements:
- Band size (underbust)
- Bust size (overbust/fullest part)
📏 How to Measure Bra Cup Size at Home in Bangladesh
All you need is a soft measuring tape, a mirror, and 5 minutes. Here’s how:
Step 1: Measure Your Band Size (Under Bust)
- Stand straight and wrap the tape snugly around your rib cage, directly under your breasts.
- Make sure the tape is level and straight across your back.
- Write down the number in inches. If it’s an odd number, round up to the next even number.
👉 Example: If your underbust measures 31 inches, round up to 32.
Your band size = 32
Step 2: Measure Your Bust Size (Over Bust)
- Now wrap the measuring tape around the fullest part of your bust, keeping it straight and relaxed.
- Don’t pull it tight—just ensure it’s resting flat without pressing into your skin.
- Write down this number in inches.
👉 Example: If your bust measures 36 inches, note it.
Step 3: Calculate Your Cup Size
Subtract your band size from your bust measurement:
Bust size – Band size = Cup size
Now refer to the cup size chart:
| Difference (in inches) | Cup Size |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD (E) |
| 6 | DDD (F) |
👉 Example:
Bust = 36 inches
Band = 32 inches
36 – 32 = 4 inches ⇒ Cup Size = D
So, your bra size is 32D

Here’s a quick example of how to measure bra cup size and calculate:
| Measurement | Result |

| Underbust (Band) | 30” |
| Overbust (Bust) | 34” |
| Band Size (rounded up) | 32 |
| Bust – Band Difference | 34 – 32 = 2 |
| Cup Size | B |
| ✅ Final Size | 32B |

🔄 Signs You’re Wearing the Wrong Bra Size
If you experience any of the following, your bra may not fit correctly:
- ❌ Cups are wrinkled or gaping
- ❌ Straps slip off your shoulders
- ❌ Underwire pokes or presses into your skin

💡 Tip: Even if you measured once, your bra size can change due to weight gain/loss, pregnancy, breastfeeding, or aging. Measure at least every 6–12 months!
🙋♀️ Common Questions About Bra Size in Bangladesh
Q1: Can I measure my bra size without a measuring tape?
Yes, you can use a ribbon and ruler or visit a lingerie store like the Sundorika Showroom for a professional fitting.
Q2: Are bra sizes the same across all brands?
No. Sizes may vary slightly by brand, but knowing your band and cup measurement helps you find the closest match.
Q3: What if I’m between two sizes?
If you’re between band sizes, go with the snugger one if you like more support, or size up for comfort. For cup size, try both and see what fits better.

The average is usually 34B or 36C, but individual sizes vary widely due to body shape and lifestyle.
