Abstract:

The relative legibilities of common words typewritten in all- uppercase and all-lowercase letters were studied in three experiments. Human subjects identified the words shown one at a time for a short period. All- uppercase printing was found to be significantly more legible than all-lowercase in all three experiments. The word-form of all-lowercase words was not found to influence word identification. The use of uppercase letters is recommended for displays.
