The Most Common Chinese Characters
© 2003 – 2007 Patrick Hassel Zein
I am working on a compilation of the 3000 most frequently used characters in modern, simplified, mainland Chinese (with references to traditional/full forms and words in which the characters are used). Since this is a rather complex page that will take a while to download, only a part of it is published here on the Net. To make the page readable, you must also first install software or fonts for that purpose.
The list was created using statistic list of Chinese characters and a number of thick dictionaries. All characters are presented in falling statistical order. Pronunciations are specified according to Pinyin and for some characters a number of different possible pronunciations are given. Examples of common words are given for most characters, however with no guarantee that all the most common words are listed or that the given examples are particularly common words. Some of the listed pronunciations for some characters are less used than other pronunciations for the same character, and in those cases translations and examples may lack. Some additional comments are given.
The current edition of the list "The Most Common Chinese Characters in order of frequency" lists more than 2,700 characters. The list is complete for the 2,400 most common characters – after that, the list contains a number of gaps. The document is coded in GB2312. The size of the document is 337 kbyte, and a printout will fill more than 100 pages. New versions containing more characters and additional details are published from time to time.

Statistics

Both Jun Da and Chih-Hao Tsai present detailed statistics for the use of Chinese characters on their web-sites. In my experience, Jun Da's statistics are quite reliable, so my list of the most common Chinese characters is based on his research.
According to the statistics, a knowledge of a given number of the most common characters should result in the following estimated understanding of the Chinese language:

100 characters → 42% understanding	1600 characters → 95.0% understanding
200 characters → 55% understanding	1700 characters → 95.5% understanding
300 characters → 64% understanding	1800 characters → 96.0% understanding
400 characters → 70% understanding	1900 characters → 96.5% understanding
500 characters → 75% understanding	2000 characters → 97.0% understanding
600 characters → 79% understanding	2100 characters → 97.4% understanding
700 characters → 82% understanding	2200 characters → 97.7% understanding
800 characters → 85% understanding	2300 characters → 98.0% understanding
900 characters → 87% understanding	2400 characters → 98.3% understanding
1000 characters → 89% understanding	2500 characters → 98.5% understanding
1100 characters → 90% understanding	2600 characters → 98.7% understanding
1200 characters → 91% understanding	2700 characters → 98.9% understanding
1300 characters → 92% understanding	2800 characters → 99.0% understanding
1400 characters → 93% understanding	2900 characters → 99.1% understanding
1500 characters → 94% understanding	3000 characters → 99.2% understanding

A tip from the teacher

Students can use the character list to create flashcards in order to train Chinese. Teachers can aslo make such cards to use in their teaching. Write the Chinese characters (possibly both simplified and traditional forms) on one side of a little piece of cardboard. Write pronunciation and explanations on the other side.
Students and teacher can also enjoy a little game that I've based on the flashcards. Rules to the game can be found on the page "Chinese Memory Game".
