How to Use the Bra Size Calculator: Step-by-Step

Follow these simple steps to find your perfect bra size:

Step 1: Measure Your Underbust

Use a soft measuring tape to measure around your ribcage directly under your bust. Record this measurement in inches.

Step 2: Measure Your Bust

Wrap the measuring tape around the fullest part of your bust. Keep the tape snug but not tight and record this measurement.

Step 3: Enter Measurements

Open the Bra Size Calculator and input your underbust and bust measurements into the provided fields.

Step 4: Calculate Your Bra Size

Click the Calculate button. A progress bar will appear, simulating the calculation process. Within seconds, your band and cup size will display.

Practical Example

Let’s say your measurements are:

  • Underbust: 32 inches
  • Bust: 36 inches

Calculation Process:

  1. Adjust band size: 32 + 4 = 36
  2. Calculate cup difference: 36 (bust) – 36 (adjusted band) = 0
  3. Cup letter from index: 0 = A

✅ Result: Your bra size is 36A

This example demonstrates how the calculator simplifies finding the right fit, eliminating guesswork.

  • Measure while wearing a non-padded bra or no bra for precision.
  • Keep the measuring tape horizontal and snug, not tight.
  • Take measurements in front of a mirror for accuracy.
  • Re-measure every 6–12 months, as body changes can affect bra size.
