Microsoft Word, for instance, suggests every even size between 8 and 28 points and, additionally, 9, 11, 36, 48 and 72 points, i.e. the larger sizes equal 3, 4 and 6 picas . While most software nowadays defaults to DTP points, many allow other units, especially code - based systems like TeX and CSS . </P>
