How the calculation is done: Our US bra size accurate calculator uses two measurements to determine your bra size: bust size and band size. Here’s how it works:

  1. Measure your bust size: Using a soft measuring tape, measure the circumference of your chest at the fullest part of your breasts. Make sure the tape is parallel to the ground and not too tight.
  2. Measure your band size: Wrap the measuring tape around your ribcage, just below your bust, making sure it’s snug and parallel to the ground.
  3. Calculate the difference: Subtract the band size from the bust size. The difference between these two measurements will determine your cup size.
  4. Determine your bra size: Combine your band size with the cup size you found in step 3. For example, if your band size is 34 and your cup size is C, your US bra size would be 34C.


  1. How does the best US bra size calculator ensure accurate results? Our US bra size calculator uses a widely accepted method that takes into account both bust and band measurements to determine the most accurate size specifically for US sizing. By using this method, our calculator provides a more precise fit compared to other calculators that rely solely on bust measurements or outdated sizing methods.
  2. Can I use the US bra size accurate calculator to find my size in different countries or brands? Our calculator provides a great starting point for finding your size in US-based brands. However, it’s essential to note that sizing may vary between countries or international brands. If you’re shopping for bras from non-US brands, consider looking for a country-specific sizing chart or a bra size conversion chart to ensure you find the best fit.
  3. What if my measurements fall between sizes in the US bra size accurate calculator? If your measurements fall between sizes, it’s best to try on both sizes to determine which one feels more comfortable and provides the best support. Keep in mind that different styles and brands might fit differently, so it’s essential to try on a variety of bras before settling on your ideal size.


With the help of our best US bra size calculator, finding the perfect fit has never been easier.
