Finding the right bra size can be confusing, but it’s essential for comfort, support, and confidence. Wearing the wrong size bra can cause discomfort, poor posture, and even back pain. That’s why we’ve created a Measure for Bra Size Calculator – a simple online tool that helps you determine your accurate bra size using just your band and bust measurements.
This article explains how the calculator works, the formula behind bra sizing, and answers common questions about finding the perfect fit.
📏 How to Measure for Bra Size
To use the calculator correctly, you’ll need two measurements:
- Band Measurement (Underbust):
- Wrap a measuring tape snugly around your ribcage, directly under your bust.
- Round to the nearest whole number.
- Bust Measurement (Overbust):
- Wrap the tape around the fullest part of your bust.
- Keep the tape level and not too tight.
Once you have both measurements, you can enter them into the calculator above.
🧮 Bra Size Formula
The bra size is calculated using two steps:
- Band Size:
- Round the underbust measurement to the nearest even number.
- Example: 31 inches → 32 band size.
- Cup Size:
- Subtract the band size from the bust measurement.
- Each inch of difference corresponds to a cup letter.
Cup Size Chart (US Standard):
- 0 inch → AA
- 1 inch → A
- 2 inches → B
- 3 inches → C
- 4 inches → D
- 5 inches → DD
- 6 inches → DDD/F
- 7 inches → G
- 8 inches → H
- 9 inches → I
- 10 inches → J
Example:
- Band = 32 inches
- Bust = 36 inches
- Difference = 36 – 32 = 4 inches
- Bra Size = 32D

Yes, sizing is not always standardized, so trying on bras is important.
6. What if the calculator shows “N/A”?
