There are 27 contracted letters and 7 shortform words in Korean braille. This article reports on a study of a unique method for calculating the space-saving capacity of all contracted braille letters and shortform words in braille books. This study found that contracted braille letters saved 20.26% over uncontracted braille letters. It also found that although there are 27 contracted braille letters, they would save spaces of braille pages in different letters such as 가, 각, 간, 갈, 감, and 강…. In the aspect of space-saving capacity, contracted braille letters save pages efficiently but some letters are very poor to do that.
