Japanese clothing size conversion table|Buy clothes from Japan


In Japan, there is an enormous selection of stylish apparel to choose from, whether you go to a clothing store or shop clothing online. However, because Japan’s sizing system differs from that of most Western countries, buying in Japan might be perplexing at times. We’ve put together a complete comparison of Japanese clothing sizes to make your life a little easier.

I. The difference between the clothes size of countries

Let’s take a brief look at some key distinctions you’ll likely face when shopping for garments in Japan before we get into detailed Japanese clothing sizes conversion.

Japanese people, on average, are leaner and shorter than their American and European counterparts. When it comes to shopping, most stores stock sizes that are closer to those of the ordinary Japanese individual.


Smaller people who have difficulty finding adult-size apparel in countries such as the United States or Europe will find Japan to be a shopping paradise. Frequently, their issue is the opposite: they are overburdened with choices.

Larger people, on the other hand, have fewer alternatives in Japan when it comes to finding clothing and footwear in their size. However, there are specific retailers in Japan that cater to the demand for larger sizes. In addition, numerous prominent manufacturers sell larger sizes online that aren’t available in their stores.

Finally, individuals with larger budgets may be interested to know that Japan is home to some of the best tailors in the world.

II. The reasons for the differences in the clothing size conversion

Shopping for clothes, regardless of your size, maybe a difficult process if you rely on the tag inside that new skirt. There is a lot of variety between countries, clothing kinds, and even within a single brand. Here are some of the reasons why clothes and shoe sizes differ so much from country to country.

Vanity Dimensions

Despite the fact that it is sad, many women throughout the world still place high importance on that small number on the label. They want to be able to fit into smaller sizes, and the apparel industry is aware of this. Vanity sizing, often known as vanity labeling, is the practice of putting a lower size on a piece of clothing than it actually is. A skirt or jacket made to a relative industry-standard size 4 will, for example, be labeled as a size 2 to make women feel better about fitting into a size 2.

– Various Manufacturing Locations

When different pieces within the same clothing line or brand fit differently, it’s one of the most aggravating aspects of the sizing issue. Customers have reported finding one item that fits well, such as a jacket, only to discover another jacket from the same brand that is too big or too tiny.

This is partly owing to the practice of having different parts of the same clothing line manufactured in different nations. While it may save money, it is detrimental to the company’s brand. Regardless of how stringent the requirements are for each component, some variation always manages to creep through the gaps and affect the final product.

– The Development of Various Sizing Practices in Different Countries

The most basic explanation for this problem is that different countries’ size charts have evolved in different ways over time. This isn’t very shocking. You’ll get a totally different black coffee in England than you will in France if you order one. Each country has its own preferences and ways of doing things, so it’s only logical that clothes and shoe sizes differ as well.

3. Japanese dress size conversion 

5-Y-PP? 21-AB-T? In Japan, clothing sizing names may resemble robot names from the Star Wars trilogy. Fortunately, we have described these denominations for you, which may appear to be unnecessarily complicated but allow you to discover gowns with perfect cuts. Three elements make up the names of Japanese dress sizes:

  • A number that indicates how big your chest is.
  • One or two letters indicate your hip circumference in relation to your chest circumference.
  • Your height is indicated by one or two letters.

Sizing for the chest

Your chest girth is determined by the first half of the clothing sizing names. The measurements in this graph are in centimeters once again.

Size numberChest
374 cm
577 cm
780 cm
983 cm
1186 cm
1389 cm
1592 cm
1796 cm
19100 cm
21104 cm
23108 cm
25112 cm
27116 cm
29120 cm
31124 cm

Size of the hips

The hip circumference is measured using the second section of the Japanese dress sizing standard. This measurement is based on your chest size in Japan.The letter “T” denotes that your hips are smaller than or equal to the size of your chest. All of the other templates are designed for women with hips that are larger than their bust. As a result, the letter “A” indicates that your hips are 4 cm larger than your chest.

Size nameHips
A+ 4 cm
AB+ 8 cm
B+ 12 cm

The length of the dress

The subject’s height is used to name the last section of the dress sizes (that means “you”). Keep taking mind that the sizes above “P” (Petite) add a few inches to the hips. When estimating your hip circumference, you must account for this fact. The calculation is tough because of the particular subtlety.

Size nameHeightExtra hips
PP (Double Petite)142 cmNo effect
P (Petite)150 cmNo effect
R (Regular)158 cm+ 2 cm
T (Tall)166 cm+ 4 cm

Other dimensions are clearly available above “T,” but Japanese producers set their own norms. If you are taller than 166 cm, you will need to ask the vendor or the business that creates the dress you wish to buy for more information.

5. Japanese bra size to the US size

Bras are another difficult area for foreign women; Japanese women are often less busty and prefer padded and lacy versions that aren’t necessarily very comfortable. Japanese bra size chart is measured using a mix of a cup and underbust measurements (the band size). To determine the band size, use a measuring tape to take the under-bust measurement.

According to the Japanese bra size converter below, in Japan, a size 32 in the United States corresponds to a size 70. A 34 corresponds to a size 75, a 36 to an 80, and so on. Size up one whole cup, sometimes two, for cup size. As a result, a 32A will become a 70B, a 34B will become a 75C, and so on. Try on a few sizes and refer to Japanese bra size conversion to discover what fits best. In many stores, the largest cup size is a D or an E in Japan.
