[AI-generated answer — Bot GPT 3.5]

To compare the height of John and Mark, it is necessary to convert the measurements to the same units. Since there are 12 inches in a foot, John's height in inches is 4 * 12 + 8 = <<4*12+8=56>>56 inches.

Mark's height in inches is 6 * 12 + 4 = <<6*12+4=76>>76 inches.
Mark is taller than John by 76 - 56 = <<76-56=20>>20 inches. Answer: \boxed{20}.
