Step 1: Measure Your Band Size

• Put on a Non-Padded Bra: This helps ensure your measurements reflect your natural shape.
• Wrap the Measuring Tape: Place it snugly around your ribcage, just under your bust. Make sure it is level all around and not too tight or loose.
• Record the Measurement: Round up to the nearest whole even number. This rounded number is your band size. For instance, if you measure 35.6 or 35.4 inches, round it to 36 inches

 

Step 2: Measure Your Bust Size

• Locate the Fullest Part of Your Bust: Wrap the measuring tape around this area, ensuring it is parallel to the ground.
• Ensure Comfort: The tape should be snug but not tight; take a deep breath to relax your body while measuring.
• Record This Measurement: Note this bust measurement in inches

Step 3: Calculate Your Cup Size

Find the Difference: Subtract your band size from your bust measurement.

For example, if your bust measures 40 inches and your band size is 36 inches, then
40 − 36 = 4

Determine Cup Size: Use the following scale to find your cup size based on the difference:

• 0 = AA
• 1 = A
• 2 = B
• 3 = C
• 4 = D
• 5 = DD (or E), etc.

Step 4: Combine Your Measurements

Combine your band size and cup size to determine your bra size:
Using the previous example, if your band size is 36 and your cup size is D, then your bra size is 36D.
