Although they are also made in Japan with the same size and number, the size will vary depending on the region (roughly divided into Kanto and Kansai). This is due to the fact that after the Japanese Industrial Standards (JIS) established a standard for the size of typefaces in 1962, some regions actively converted to the new standard, but the Kanto region and other regions did not update it. So if you want to buy used type for typesetting, you must pay more attention to the size specifications. Types in Western countries can also be roughly divided into two types.
The United States, the United Kingdom, Spain and other countries mainly use the "American Point" mentioned in Q3, while the European photo retouching service countries use the "Didot Point" with 1 point = 0.3759mm. The different sizes are due to the different benchmark values of "inch". Filling in between the type and type as a filler for the blank of the layout (called lead angle in Taiwan) is also divided into two point-based specifications and cannot be mixed with each other.
So if you want to order lead type from overseas, don't forget to buy lead angles of the same order specification to match the typesetting. Of course, the height of the typeface will also vary from country to country. The height of the typeface is roughly divided into 0.918 inches (23.32mm) used in the United States, Britain, Spain and other countries, 0.928 inches (23.57mm) in Taiwan, Germany, France and other countries, and 0.923 inches (23.57mm) in Japan. 23.45mm).
