How to Measure Your Bra Size Accurately

  • Start by wearing an unpadded bra that fits you well.
  • Take a measuring tape and wrap it around your bust, just above the band of your bra. Make sure the tape is level with the ground.
  • Note down the measurement in inches or centimeters.
  • Next, measure your underbust by placing the tape directly under your bust, where the band of your bra sits.
  • Again, record this measurement.
  • To find your band size, subtract the underbust measurement from the bust measurement. If the difference is less than 1 inch, round down to the nearest even number. If it’s greater than 1 inch, round up.
  • For example, if your underbust measures 30 inches and your bust measures 34 inches, the difference is 4 inches. Your band size would be 34.
  • To determine your cup size, subtract the band size from the bust measurement. Each inch difference corresponds to a cup size. For example, if the difference is 1 inch, you’d be an A cup.
  • If the difference is 2 inches, you’d be a B cup, and so on.
  • Now you’ve your band size and cup size, which you can combine to determine your accurate bra size.
  • Remember, bra sizes can vary between brands, so it’s always best to try on different sizes to find the most comfortable fit.
