In order to examine the legibility of the Hangul letters which is a syllabic, the three kind of visual charts were made of the ninety eight($14{\times}7$) Hangul Gothic type letters by the laser printer. These Hangul letters were constructed with the 13 consonant letters which are 'ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅌ, ㅍ, ㅎ', and the 6 vowel letters which are 'ㅏ, ㅓ, ㅗ, ㅜ, ㅡ, ㅣ'. The two examination methods were used, One is the discriminating the letters on the visual chart by men having 1.5 visual acuity. The other is the using the laser printer's resolution. Obtained data by these examination methods are the minimum readable size values of the letters and the maximum readable distance values from the reader to the objects. From these data the relative legibility of the Hangul letters were calculated, where the letter ㄱ was chosen for the standard. This resultant data were analyzed. In this result, the mean legibility of these Hangul letters descended in the order of 'ㄱ, ㄴ, ㅅ, ㄷ, ㅈ, ㅇ, ㅁ, ㅋ, ㅌ, ㅍ, ㅎ' Which are the consonant letters being in these letters. And the mean legibility descended in 'ㅣ, ㅡ, ㅏ, ㅗ, ㅓ, ㅜ' order. The mean legibility is dependent on used consonant letter more then on used vowel.
