# Interline spacing

What TeX/LaTeX parameter specifies the distance between:

• the bottom of one line and
• the top of another line

I don't think baseline skip is what I want (since it measures the distance between the baseline of of two lines).

I want to make sure that there is at least a 2pt margin between the bottom of one line and the top of another line.

you probably realize this, but this can result in very uneven spacing between lines, taking into account that some lines may have no ascenders or (more often) no descenders, or (in an extreme case) may consist only of dots or a horizontal rule. – barbara beeton Sep 26 '12 at 12:27
