Japanese (JP) and South Korean (KO) bra sizes are identical and are shown in inches and centimeters. The sizing data is verified for accuracy and can be used as reference. Due to the large amount sizes, the tables are divided by cups.

About JP and KO Sizing Convention

Japanese sizes are abbreviated as JP and South Korean as KO. The abbreviations are written together with the size, for example "JP/KO 65B" or "65B (KO)". International bra brands often only write JP on the size tags but the size does in fact refer to both JP and KO.

Use size charts to convert JP and KO sizes to other conventions.

Bra sizes following the Japanese (JP) and South Korean (KO) sizing convention are based on measurements in centimeters. The number represents the bra band size and the letter the cup size.

Bands are measured tightly under bust, cups are measured loosely over the fullest part of the bust. If you are between two band sizes, choose the smaller. If you are between two cup sizes, choose the bigger.

Learn why most women choose too big band size and too small cups.

JP/KO bands are divided in steps of 5 cm and are named after the under bust measurements. For example, "70" refers under bust measurement of 70-75 cm, "75" refers to 75-80 cm, and so on. Japanese and South Korean band sizes are identical to European (EU) and International (Int).

The cups are based on the difference between the over bust (at the fullest part of the bust) and under bust measurements, with the under bust rounded down to the nearest multiple of 5. Japanese and South Korean cups often start at AAA or AA and continue alphabetically with A, B, C and so on. Cups increase in steps of 2.5 cm. AAA has a over/under bust difference of 5-7.5 cm, AA has 7.5-10 cm, A has 10-12.5 cm, and so on.

Cup size example: Measuring over bust 84 cm and under bust 68 cm, the under bust must first be rounded down to the nearest multiple of 5. This gives us 84-65=19. The difference of 19 cm equals to Japanese or South Korean D-cup.

JP/KO and EU bra cups are not identical! Most size conversions claim that they are, but this wrong. EU cups increase in steps of 2 cm, while JP/KO in steps of 2.5 cm, which is closer to the US and UK cup sizing that is based on 1 inch steps (1 in = 2.54 cm). Japanese and South Korean AAA and AA are the only multiple letter cup sizes.

This page contains tables showing JP and KO sizes in both centimeters (cm) and inches (in). Band and cup measurements are shown individually.
