Bra Fit Calculator

Finding the right bra size is one of the most overlooked yet essential aspects of women’s comfort and confidence. Many women unknowingly wear the wrong size, leading to discomfort, poor posture, and even long-term health issues. That’s where our Bra Fit Calculator comes in.

This tool is designed to help you determine your accurate bra size based on simple measurements. Instead of guessing or relying on outdated sizing charts, you can now get a precise fit tailored to your body.


How the Bra Fit Calculator Works

The calculator uses two key measurements:

  • Band Size (Underbust Measurement)
  • Bust Size (Overbust Measurement)

Formula Logic:

  • Band Size = Rounded underbust measurement
  • Cup Size = Bust – Band difference

Cup size is determined by the difference:

  • 1 inch = A
  • 2 inches = B
  • 3 inches = C
  • 4 inches = D
  • and so on

How to Use the Tool

  1. Measure your underbust (around ribcage)
  2. Measure your bust (fullest part)
  3. Enter both values into the calculator
  4. Click calculate
  5. Instantly get your correct bra size

Practical Example

Let’s say:

  • Underbust = 32 inches
  • Bust = 35 inches

Difference = 3 inches → Cup C

Result: 32C
