11. Type Units The unit called point=1/72 inch 12 points=1 pica 6 picas=1 inch

12. It’s difficult to predict how large type will look from its point size because type is measured by its body height.

13. All of these samples are the same point size, but Helvetica looks much larger than the others because of its greater x-height. Compare the width of the other letters to Helvetica, too.

14. The conventional notation is to list the number of picas first, then a “p,” then the points. This would read “3 picas, 2.5 points.” It would equal 20.5 pt. or about 0.285".

15. Type Specification
One em in a 12-point typeface is 12 points wide. The term is derived from the traditional width of the capitol M, the M was commonly cast as the full-width of the square for printing presses, however now this term has evolved.
