What cup size is the breast size?

In recent years, discussions about women’s bra sizes have continued to heat up on social media, especially regarding the relationship between breast size and cup size. Many women often feel confused when choosing underwear, not knowing how to correctly measure their bust and choose the right cup size. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the relationship between breast size and cup size, and provide structured data for reference.

1. Basic concept of cup size

What cup size is the breast size?

Bra cup is one of the standards for measuring breast size, usually expressed by letters (such as A, B, C, D, etc.). Cup size is determined by the difference between the bust and underbust measurements. The following is the corresponding relationship between cup size and difference:

Difference (cm)cup size
7.5-10A
10-12.5B
12.5-15C
15-17.5D
17.5-20E
20-22.5F

2. How to measure bust correctly

Measuring your bust is a key step in choosing the right bra cup. Here's how to measure it:

1.Under bust measurement: Use a soft tape horizontally around the lower part of the chest. Keep breathing naturally when measuring, and do not make it too tight or too loose.

2.Upper bust measurement: Use a soft tape horizontally around the fullest part of the chest, keeping it upright or leaning slightly forward when measuring.

3.Calculate difference: Subtract the lower bust from the upper bust, and compare the difference with the cup chart to select the appropriate size.

3. Analysis of hot topics on the entire network

According to social media data in the past 10 days, the following are the hot topics in the discussion about cup sizes:
