What Is The Smallest Cup Size Of Bras For Women?

Cup sizes matter when getting a bra. This functional clothing for women makes part of a selection of women’s underwear necessary to provide support and comfort. However, what is the smallest cup size? What’s the biggest cup?

If you fall between bra sizes (not too small and not too big), you will find it easy to get a fitted cup just for you. Nonetheless, people on the end of the smaller spectrum of breast sizes can find this daunting, especially when the supposed cup doesn’t fit.

Moreover, you have to remember that bra sizes are a set of characteristics of the chest area, not only the cup. While you find your band size, you might not necessarily get your small cup size. So how do you go about it?

Read this article to find the smallest cup size for bras and its equivalent.

What is a bra cup size?

A bra cup size is a measurement obtained from the difference between the fullest part of the breast and the band area.

The difference between the fullest part of the breast (around the nipple) and the band is directly proportional to cup size. That is, the higher the difference, the larger the cup.

Cup sizes are represented in the letters. You have cup sizes ranging from A to H and on.

However, do not confuse a cup size for a bra size. Bra sizes are a merge of cup sizes and band areas (over the bust or underbust).

For example, you have 36B or 36C. The number is the band in inches, and the letters represent the cup. However, some countries measure in centimeters (e.g., 74C).

Conclusively, cup sizes represent breast fullness, and bra size is the computation of the cup size and circumferential measurement of the underbust.

How to find your cup size

To find your cup, follow these steps:

  • Get a measuring tape.
  • Start with the band measurement. Simply wrap the tape tightly around the circumference of your torso, under your bust, and around the ribcage.
  • If the number you get is even, add +4; if it is odd, add + 5. This is your band size.
  • Then, measure the circumference of your bust by placing the tape parallel across the fullest part of your breast.
  • Finally, subtract the band from the bust size. This will give you your cup size. The higher the inch, the higher the cup.

Note: Wear a comfortable and firm bra with your breast resting fully in the cup when measuring your cup size. This will give you the most accurate bust size.
