Abstract
An index was developed to determine the congruency of letter pairs in the lower-case English alphabet in Century Schoolbook print. The index was based on the ratio of common area to independent area. The congruency matrix of the 325 letter pairs was factor analyzed. Five factors indicated major letter groups and illustrated critical features for discrimination within letter groups.Keywords
