Bra Tips: Understanding Cup Size vs. Band Size

Bras can help you feel pretty and provide support and shaping for your curves. However, the truth is that many women are wearing bras that do not fit. You may be one of them.

In order to find a comfortable bra that fits great, get help from experienced lingerie fitters. You can do this online and even get a virtual bra size test to help you find the bra that fits you best. Knowing the basics of bra sizing helps you understand what your measurements mean. 

What Does Cup Size Mean and How To Measure It?

Bra sizes are made up of two parts: a number and a letter. Your cup size is the letter.  Contrary to general thought, bra cup sizes do not measure the volume of breasts. Rather, your cup size is the difference between your bust measurement and your band size. Specifically, cup size equals your bust measurement minus your band size. 

To find your cup size, take these steps: 

• Determine your band size.
• Measure around the fullest part of your breasts, at the level of your nipples.
• Subtract your band size from your bust measurement. 

For example, if your band size is 36 and your bust measurement is 38, the sum is two. Referring to a bra size chart, these measurements mean you are a 36B, representing band size and cup size. Bra sizing tools are easily available online. 

What Does Band Size Mean and How To Measure It?

Your bra size includes both your cup and your band measurements. The number in your bra size represents your band measurement. The band on your bra is responsible for the support your breasts receive. The straps merely help hold the bra in position. 

Band tightness determines how the bra will work for you. The principles are:

• If you want lift from your bra, the band needs to be tighter. Bands that are too loose can lead to pain in the shoulders, neck, and back. 
• If you do not need or want lots of lift, your band can be looser. 

To measure your bra band size, when you are braless or wearing a looser bralette, wrap a measuring tape around your back, and bring it around under your breasts where the band will sit. Pull the tape as tightly as you want the band to fit. To get the right band size for your needs:

• If you want a tighter band, use your exact measurement.
• If you want a slightly looser band, add two to your measurement. For example, if your band measurement is 34, opt for a 36 band size. 

On the other hand, if your bra size is 34D, and your cup size too big but band fits, keep the band size but go down one cup size to a 34C. 

Bra sizing may seem complicated, but when you know your measurements, finding a bra that fits becomes much simpler. Seek out help from experienced lingerie fitters. You can find lots of help online to ensure you are wearing the right bra for you.
