How to Measure Your Breast Size: A Step-by-Step Guide

Getting the right bra size is essential for both comfort and support. Follow these simple steps to accurately measure your breast size using just a cloth tape measure.

Step 1: Measure Your Underbust

Start by wearing your most comfortable, non-padded bra. Wrap the tape measure around your ribcage, just under your breasts. Ensure the tape is flat against your skin, parallel to the ground, and isn’t digging in. Keep the fit loose and relaxed, then record this number as your underbust measurement.

Step 2: Measure Your Upper Bust

With the same comfortable bra on, wrap the measuring tape around the fullest part of your chest, usually at nipple level. Make sure the tape stays parallel to the ground and snug against your skin without compressing your chest. Record this measurement as your upper bust.

Step 3: Determine Your Cup Size

To calculate your cup size, find the difference between your upper bust and underbust measurements. Generally, for every inch of difference, your cup size increases by one. For instance, if the difference is 2 inches, you would typically wear a B cup.

Important Tips:

  • Ensure the tape measure isn’t too tight or too loose—it should rest comfortably on your body.
  • Breathe normally while taking the measurements to get accurate results.
  • Since breast size can fluctuate due to factors like your menstrual cycle, it’s a good idea to measure multiple times at different points in your cycle.

By following these steps, you’ll be able to find your correct bra size, ensuring better comfort and support throughout the day.
