Measuring the bust line correctly is vital, if you want to know your bra size. With the guidance given in this article, you will know how to measure the bust line.

How To Measure Bust Line

It is vital to know the exact size of your bust line because an uncomfortable bra can be harmful to your health. Tight-fitting bras may put undue strain on your back and shoulders, while a loose one can hamper the firmness of the delicate breast tissues. A tape measure is the most appropriate way to figure out the measurement of your bust line. By using a flat, straight tape, directly on your skin and under your bust line, you will be able to find out the correct size of your bra. Given below are tips on how to measure your bust line.

Measuring Your Bust Line
Method - 1
  • Make use of a tape measure to know the measurement of the bust line.
  • Take the measurement directly on your skin. Place the inch tape on the fullest area of your area and nowhere else.
  • Flatten the tape measure by holding it tightly against your skin. Do not leave extra space to measure your bust line.
  • Make sure that you are holding the measuring tape appropriately, neither too tight nor too loose in your bust line.
  • Measure it carefully, so that you get the right size for your bra. 
Method - 2
  • To determine your band size, the first step would be to put on your best fitting unpadded bra.
  • With the help of a measuring tape, gauge your size. For this, you need to put the tape around your rib cage, directly under the bust. Ensure that the tape is flat and straight against your back. Measure tightly.
  • In case the measurement has a fraction, round down if it is less than half and up if it is more than half. For instance, if your measurement is 30 and 1/4 inches, round down to 30. However, if your measurement is 30 and 1/2, round up to 31.
  • Now, add 5 inches to your rib cage measurement. If you come up with an odd number, round up to the next even number, as bras are available only in even number sizes. For instance, in case your rib cage measurement is 30 inches, adding 5 inches equals 35. You would then have to round it up to the next even number, i.e. 36. This would be your band size.
  • Now, again take the measuring tape and measure around your chest at the fullest part of the bust line. It is usually across the nipples.
  • At the time of measurement, make sure that the tape is horizontal, straight and flat all the way around your body. Round up or down to the nearest whole number. This would be the bust line measurement.
  • To determine the cup size, subtract your band size from your bust line measurement. The difference would be the cup size. 
For a difference of ½ ", the cup size is AA.
For a difference of 1", the cup size is A.
For a difference of 2", the cup size is B.
For a difference of 3", the cup size is C.
For a difference of 4", the cup size is D.
For a difference of 5", the cup size is DD.
For a difference of 6", the cup size is F.
For a difference of 7", the cup size is G.
For a difference of 8", the cup size is H.
