Pixels explain more than character counts
Two titles with 55 characters can have very different widths. Wide capitals take more space than narrow letters. Compare the measured width and visible lines, then put the most useful words early.
Our desktop preset uses 600 pixels for the title and two 480 pixel description lines. Mobile uses 340 pixel lines. These are adjustable viewing contexts through device selection, rather than official Google limits.
