The 34C bra size is one of the most desirable bra sizes overall, as are most C cups. This is because 34C boobs are on the larger side, which as you probably know is considered very attractive in Western society.
In this article, we’ll look at how big 34C breasts are, how to measure if you should be wearing a 34C bra, what are the sister sizes of this bra, what 34C boobs actually look like, and much more about this bra size.
Let’s dive in!
What Is a 34C Bra Size?
A 34C bra size is the bra size where the band measurement (measured right under the breasts) equals 34 inches and the bust measurement (measured at the center of the breasts where they’re the largest) equals 37 inches.
Let’s explain this so that it’s much clearer.
You probably already know that bra sizes have a “number” and a “letter” part (34C, 34D, 38C, and so on). It’s important to get both parts correct so that your bra fits right.
First, you must measure your band size. To do this, wrap a measuring tape around your ribcage, just below your breasts. Make sure the tape is snug but not too tight. The tape should be parallel to the ground and should not be twisted.
If you get an odd number, increase it by 1 to get to an even number, since that’s how bra sizes are generally defined (for example, if your band size is 33 inches, round it up to 34).
The number you measure this way is the “number” part of the bra size, or your band size.
In a 34C bra size, the band size measured like this will equal 34 inches (or 33 inches).
Next, measure your bust size. Wrap the measuring tape around the fullest part of your bust, making sure it’s parallel to the ground. Take note of the measurement in inches.
In a 34C bra size, the bust size measured as explained here will be equal to 37 inches.
To determine your cup size, subtract your band size from your bust size. The difference between the two measurements will give you your cup size. If the difference is 1 inch, you’re an A cup, if it’s 2 inches, you’re a B cup, if it’s 3 inches you’re a C cup, and so on following this table.
In a 34C bra size, the difference between the bust size and the band size is 3 inches (37 inches – 34 inches = 3 inches). That’s where the “C” in “34C” comes from. The “34” in “34C” comes from the band measurement.
More About the 34C Bra Size
The 34C is one of the most desirable bra sizes out there, as are most C cup sizes.
This is also shown by a survey of 2,000 Americans and Europeans, where the large majority of people consider the C cup size as the ideal size.
This was true for both men and women. More women chose the C cup size as the ideal size than they did for all other cup sizes combined.
34C boobs are large enough to be desirable, but usually not large enough to cause significant back pain or affect your posture. Another advantage of 34C breasts is that you have a very good selection of bras.
In general, C cup boobs are a very common choice for women who undergo a breast augmentation procedure.
What 34C Boobs Look Like (34C Bra Size Examples)
Enough talk, let’s look at examples of 34C boobs. We’ll point to some celebrities who are wearing a 34C bra size.
Since this is a common bra size, there are many prominent celebrities with this reported bra size.
A celebrity who is a 34C bra size is actress Jennifer Aniston. Given this bra size, her band size is 34 inches and her bust size is 37 inches. Another famous actress with 34C breasts is Angelina Jolie.
34C Sister Size (34C Bra Size Equivalent)
The closest sister sizes of the 34C are the 32D and the 36B. The 32D is one cup size larger and one band size smaller, while the 36B is one cup size smaller and one band size larger. Some other sister sizes of the 34C are the 30DD, 32D, and the 38A.
If you’re not familiar, sister bra sizes are different sizes that have the same cup volume. For example, the 30DD, 32D, 34C, 36B, and 38A will all hold a similar amount of breast tissue, since the band size of sister bra sizes increases as the cup size decreases.
Sister bra sizes can be useful if you can’t find a bra in your exact bra size. In such a case, a sister bra size is an option. Another use case of sister bra sizes is if your exact bra size isn’t comfortable enough even though the cups fit well.
For example, the underband might be too tight or too loose. If the cups fit well but the underband is tight, you can try a sister size up (one band size larger and one cup size smaller. For example, if the band of a 34C bra is tight, try a 36B.
On the other hand, if the cups fit but the underband is loose, you can try a sister size down (one band size smaller and one cup size larger). For example, if the band of a 34C bra is loose, try a 32D.

34C Bra Size in Inches
Measured in inches, a 34C bra size means that your band measurement equals 34 inches (that’s where the “34” in “34C” comes from) and your bust measurement equals 37 inches. The difference between the bust size and the band size is 3 inches, which translates to a C cup size (that’s where the “C” in “34C” comes from).
