What is the difference between full-width characters and half-width characters?

In our daily lives, we often encounter the two concepts of full-width characters and half-width characters, especially in input methods, typesetting, printing, etc., which involve the use of these two characters. So, what is the difference between full-width characters and half-width characters? Let us discuss this issue below.

First of all, full-width characters and half-width characters were concepts originally introduced by Chinese typewriters. The so-called half-width characters are characters that occupy half the width of a character, usually referring to English characters and Arabic numerals. Full-width characters are characters that occupy one character width, usually referring to Chinese characters, Japanese characters, Korean characters, etc. In computers, for characters that occupy half a character width, their ASCII codes are characters in the range from 32 to 126; while the Unicode encoding of full-width characters has a specific range.

Secondly, there are some differences in the display effects of full-width characters and half-width characters. Full-width characters are wider, making text appear fuller when displayed, while half-width characters are relatively narrower, making them appear more compact. In typesetting design, choosing full-width characters and half-width characters according to actual needs can achieve better visual effects.

In addition, the input methods for full-width characters and half-width characters are also different. When operating the computer, we will find that full-width characters are automatically generated when entering Chinese characters, and half-width characters are automatically generated when entering English characters and numbers. This is to unify the size and spacing between Chinese and English characters, making the entire text more coordinated and beautiful.

In general, full-width characters and half-width characters play different roles in the computer field, and they each have specific uses and expressions. The correct understanding and use of full-width characters and half-width characters is very important to improve the readability and aesthetics of text.
