Inter-letter, Inter-word, Dyslexia, Reading Accuracy, Reading Speed



Recent research studies have shown that increased inter-letter and inter-word spacing has a positive effect on the reading speed and accuracy of students with dyslexia. A few of these studies also included the use of increased font size. Research that has included using fonts designed for dyslexics in addition to increased font size has not produced favorable results in increasing reading accuracy and speed. In relationship to previous research our results have shown that a .5 inter-letter and inter-word spacing has a marginal positive effect on reading accuracy and speed. The use of .3 and .7 inter-letter and inter word spacing showed no change in reading accuracy and speed or even a negative performance in reading accuracy and speed.
