How to Measure Bra Cup Size at Home

Wearing the right bra size is essential to every woman’s comfort and confidence. The wrong bra size can not only make you feel uncomfortable, but it can also mess up a good outfit. How do you know if you’re wearing the right size? If you notice wrinkling in the bra cups, or if your bra moves up every time you extend your arms, then it might be time to rethink your bra size. Learn how to measure bra cup size at home to find out in the comfort and privacy of your own space.

  1.  Before you determine your bra size, it is important to know how the right bra should look and feel on you. First, it should provide enough side coverage. There should not be any tissue protruding out from the area of your breasts under your armpits. Also, the cups should contain each breast, especially the top half, which a too-small cup size would not, thereby resulting in spillage and an obvious partition line. Most importantly, the band at the base of the bra should fit snugly around your rib cage. As for whether the strap is too loose or not too tight, try to slip some fingers underneath.

    more than two fingers fit, chances are it’s too loose, and if a single finger can’t fit, it’s too tight.

  2.  Determine your band size. Position a tape measure at the base of your breasts, and wrap it around your rib cage. Make sure it is parallel to the floor. Keep your arms down while measuring, and write down the measurement in inches. If it’s an even number, it is usually your band size. For odd numbers, round it up to the next even number. To be sure, however, try out bras in sizes below and above this measurement. For example, if you measure 33 inches, try out bras in size 32 and 34, and see which is most comfortable for you.

  3. Measure your bust. Determining cup size is a bit trickier. It involves accurate measuring, some calculations, and referring to a chart provided in step 4. First, determine the fullest part of your breast. To do so, it’s best to bend over so that you can include all of the breast tissue in your measurement to get a more accurate size. Wrap a tape measure around the fullest part of your breasts and your entire torso. Make sure to keep it parallel to the floor, especially around your back. If needed, ask a close friend or partner to help. Also, do not pull the tape measure too tight; it should not cut into your breast tissue. Write down your measurement in inches.

  4. Calculate your cup size. Find the difference between the measurement in step 2 and the measurement in step 3, and refer to the chart below

    If the difference is: Your cup size is:
    Less than 1 inch1 inch2 inches 3 inches 4 inches 5 inches 6 inches 7 inches 8 inches 9 inches 10 inches AAAB C D DD DDD (E in UK sizing) DDDD (F in UK sizing) G/H (FF in UK sizing) I/J (G in UK sizing) J (GG in UK sizing)
  5.  Now put the two sizes together to get your bra size. If your band size is 34 and your cup size is B, then you can safely say that your bra size is 34B.

Once you’ve learned how to measure bra cup size at home, you can go out and buy new bras that fit you perfectly. A properly fitting bra boosts your everyday comfort and makes your bust appear at its best.
