Why Accurate Bra Sizing Matters
Many women wear the wrong bra size without realizing it. Common issues include:

- Poor posture
A well-fitted bra improves appearance, confidence, and physical comfort. Using a bra calculator removes guesswork, giving you the exact size that fits your unique body measurements.
How to Use the Bra Cup Size Calculator
Using the Bra Cup Size Calculator is straightforward. Follow these steps:
- Measure Your Band Size:
- Wrap a measuring tape around your ribcage, directly under your bust.
- Note the measurement in inches. This is your band size.
- Measure Your Bust Size:
- Wrap the measuring tape around the fullest part of your bust.
- Ensure the tape is snug but not tight.
- Enter Measurements:
- Input your band size and bust size into the calculator fields.
- Click “Calculate”:
- The tool instantly calculates your bra size and displays the result.
- Optional Reset:
- Click “Reset” to clear the fields and enter new measurements.
Understanding Your Results
The calculator uses a simple formula:
Cup Size = Bust Size – Band Size
- AA: Difference < 1 inch
- A: Difference < 2 inches
- B: Difference < 3 inches
- C: Difference < 4 inches
- D: Difference < 5 inches
- DD/E: Difference < 6 inches
- DDD/F: Difference < 7 inches
- G: Difference < 8 inches
- H+: Difference ≥ 8 inches
The final result combines your band size with the calculated cup. For example, if your band size is 34 and your bust is 38, your bra size is 34D.
Example Use Case
Let’s say Jane wants to determine her bra size:
- Jane measures her band at 32 inches and her bust at 36 inches.
- She enters the numbers into the calculator and clicks Calculate.
- The difference between bust and band is 4 inches, which corresponds to cup size C.
- The calculator displays Jane’s bra size as 32C.
This accurate sizing helps Jane shop confidently without trying on multiple bras.
