Leading will always depend on your chosen font size and measure (or line length). In general, the longer the measure, the longer the leading should be. Therefore, presenting a chart of the most popular choices for leading in pixels wouldn’t make sense here. More appropriate would be for you to use a relative unit, such as an em or percentage value, that determines the relation between leading and measure and between leading and font size.
Note that 1.5 is a value that is commonly recommended in classic typographic books, so our study backs up this rule of thumb. Very few websites use anything less than that. The number of websites that go above 1.48 decreases as you get further from this value.

According to a classic rule of Web typography, 55 to 75 is an optimal number of characters per line. Surprisingly, our study shows that most websites have a higher number. We counted how many characters could fit on one line using the design’s default font size. The result, which is an average of 88.74 characters per line (maximum), is extremely high. Of course, this maximal number is different from the average number of characters per line, which in general ranges between 75 and 85 characters per line. Still, the range is way above the conventional range – quite peculiar.
