<aside> ℹ️ Line spacing is the distance between the baseline of one line and the other line. Well-adjusted line spacing makes texts readable and scannable. This means that your interface will be attractive to users so that they will spend more time in it, and it will be easier for them to reach a goal or get information.

Line spacing is the distance between the baseline of one line and the other line.
Line spacing is measured relative to the font size as a percentage or number ratio. Usually, comfortable values for text are between 1.3 and 1.7. For headings from 1.1 to 1.4.

The value of line spacing is a specific ratio to the text size.
The proper line spacing affects the readability. If this value is too small or vice versa, too large, the text is difficult to read.

Properly chosen line spacing makes the text more readable.
The only optimally chosen line spacing value allows the user to read text comfortably.
The choice of line spacing depends on several factors. Unfortunately, there is no universal value you can use in all possible cases. Line spacing must be adjusted manually, depending on the conditions and context.
The starting point can be a value of 1.5 of the text size. This often works well for long texts with different fonts. However, this is only a starting point; you may need to change this ratio depending on the typeface, line length, and sometimes on text size you choose. But you can always start at 1.5 or 150% of the text size and then think about fine-tuning.
One of the proper choice factors is the subjective feeling of reading comfort. There are no strict rules in this aspect. Compare texts with different line spacing, read, and understand which value allows you to do it most comfortably.

Test and read texts with different line spacing to see which one is more comfortable.
