The top line gives the UA (unit arrangement) serial number, and the second line the typeface series number. Then in each row, the columns give the upper case (caps) units, then the lower case units, of the named letter. Punctuation and figures are not shown. For composition, each row in the diecase that holds the matrices corresponds to a given unit value that is matched by the stopbar case and the wedge. For display, the physical width of a given letter can be calculated from the set and point size of the typeface. The typeface set widths are not shown here, but knowing that Monotype's base unit is 0.166÷18, i.e. 0.0007685″ then for example, Greek Upright series 90 in 10pt is 9¾ set which makes one unit of it to be 0.0007685″×9¾ i.e. 0.00749″. As series 90's UA is 26, the table gives the letter A as 13 units, so its width is 13×0.00749″, i.e. 0.0974″.
