For example, the average breast cup size is lower in well-documented regions like Africa and Southeast Asia, making the C cup size relatively large there. In contrast, this is a smaller-than-average cup size in Europe, the United States, and the United Kingdom. In most cases, a D grade is a fair place to begin with jumbo mugs.

A C-cupped bra is roughly the size of a large peach or grapefruit. A C cup bra should provide adequate support for these fruits.

How big is a C cup bra in inches?

When measured arbitrarily in inches, a C cup should fall between 33.5 (4/5) and 43.4 (1/4) inches.

Bra sizes are quantified by band widths across the spectrum. On the other hand, a C cup indicates a three-inch gap between the bust and band sizes when shopping for a bra.

How big is C cup bra in centimeters?

The range of measurements for a C-cup bra is 82–105 centimeters, measured around the fullest part of the bust (nipple area).

In Europe and other parts of the world, size charts typically use the centimeter.

How to know you are a C cup

You need to take your measurements if you care about your C cup (or any other) status. Going to a specialty store or regular store, or taking your own measurements, will accomplish this.

A measuring tape and your most relaxed bra are all that’s required. This is a job for the imperial system of measurement.

Band measurement:

  • The first step is to determine your band size. Both the underbust and the bust measurements will do.
  • Wrap the tape around your upper bust after pulling it out from under your arm. Maintain a snug but comfortable fit with the tape. If the number you get is even, use that as your standard. Round up to the nearest even number if the result is an odd one.
  • Also, round up to the nearest whole inch if your measurement is less than an inch.
  • For this, you can either go braless or wear a non-padded bra.
  • The first step in taking a “under the bust” measurement is to wrap the measuring tape around your torso, starting under your bust and ending at your rib cage. Wear it so that it drapes flat against your bra straps. Wrap the tape snugly around your midsection.
  • With an even number, add +4, and with an odd number, add +5. E.g., 31+5 = 36 or 32+4 = 36.
  • What you just found out is your band size. In other words, the sum must be divisible by 2.

Bust measurement:

  • Take your bust circumference measurements as well.
  • Measure around your fullest part of the bust. The apex is where your breasts are at their fullest (the nipple point).
  • The tape should wrap your bust snugly. Locate your contact information.
  • Measurements that end in fractions of an inch should be rounded up to the next whole inch. It’s better to decrease a number when busting than increase it.
  • Your bust size is the number of inches. For the sake of rounding, it doesn’t matter if it’s an odd or even number.

Cup size:

  • Band size is subtracted from bust size to determine cup size.
  • Each inch is represented by a letter. It’s a case of “one more inch” for each additional letter.
  • There is a three-inch discrepancy between A and C cups.
  • If your band size is 36 and your bust size is 39, there is a difference of 3 inches. In other words, you wear a size C cup bra.

What are the bra sizes for C cups?

There are typically five main sizes for C cups, including 23C, 34C, 36C, 38C, and 40C. Nonetheless, sizes up to 48C are available. Bra sizes are a combination of the band size (in numbers) and the cup size (in letters).

Although they are all size C, these bras are not the same. The bands they fall into are different. Since this is the case, not all women who are a C cup should use the same size bra.

Also, the larger the band size, the larger the breasts appear. To illustrate, a slim 32C or 34C will make a C cup bra look even larger. In the meantime, it appears to be more appropriate for a size 38B bra. Your bust will look either larger or smaller depending on your overall proportions.


Is C cup common?

What is the difference between C and D cup bras?

Larger than a C cup is a D cup. It’s an inch between them. The difference between the bust and the band size in case C is three inches. D measures in at a paltry 4 inches. Due to their similar dimensions, they are frequently confused with one another.

On the other hand, there are “sister sizes” where a C cup can wear a D cup bra, and vice versa.

The C cup is for average-sized bras.


A C cup indicates a woman has a moderately sized bust. Depending on the wearer’s overall proportions, a cup size of C could appear either large or small.

If you feel like your bust size is still lacking, the sister size trick can help you achieve the appearance of a larger bust.

However, a C cup is the ideal size, neither too large nor too small.
