In this paper authors examine readability and legibility of text on iPad and compare it partially to reading from computer screen and paper. Following previous research, two independent variables were measured: speed of reading (T) and subjective difficulty of reading (Z). 220 university students aged 18÷48 participated in the experiment and were divided into 11 groups of 20 participants. Key findings are as follows: Sans serif Gotham font is more readable and legible on iPad than Minion Pro serif font, although, when presented in bigger font sizes there is no significant difference between the two letter cases; two column spread of text was the hardest to read, giving fewer number of characters per row; layout of text with 79 characters per row and above should be readable and legible enough for reading texts on iPad; considering quality of reading, texts displayed on iPad can replace texts printed on paper.
