The measured lower bust is directly used as the first part of the size representation.
The order of the cups is strictly alphabetical.
The grading of cups is more detailed.
International general bra size calculation method [edit]
The bra size can be calculated by substituting the measured lower bust and bust into the following formula:
Lower bust+1 1 cm+n × 2 cm = bust.
Cup n = (bust? Lower bust? 1 1) / 2
The number n stands for cup (A= 1, B=2, C=3, and so on). For example, the difference between the bust and the lower bust 15 cm (n=2) always represents the B cup.
International common bra size comparison table [edit]
The lower bust and cup can be determined by the following two tables:
Lower bust (cm)
Lower bust size
63–67 65
68–72 70
73–77 75
78–82 80
83–87 85
88–92 90
93–97 95
98– 102 100
103– 107 105
108– 1 12 1 10
Chest circumference subtraction
Lower bust (cm)
cup
10– 12 AA
12– 14 A
14– 16 B
16–18℃.
18–20 days
20 to 22 degrees east longitude
22 to 24 degrees Fahrenheit
24–26 grams
26 to 28 hours
Cup symbols (cups e, f, g ...) can be expanded alphabetically.
For example, 75B indicates that the lower bust is 75cm and the bust is about 90cm.
