There are many variations in how the type is distributed within a double case. Twenty-nine different double case lays have been encountered, with cases having five, six or seven rows in the Upper section, and ignoring those in the U.S. style with a divided box above the i box. Shown above are those characters that do not vary their positions (the Upper section may or may not have the top two rows). The exceptions to this standard are Curwen with thins and mids where ens and ems go, Lindley who moves x z v p w, Alembic and Central St Martins who replace thicks with mids, Reading who replace p with thicks and thicks with mids, Incline who moves z x v p w f g and replaces thicks with mids, Talbot who move the caps up one row, and have U J in alphabetic order.Old Clewer, Alembic, Incline also have U and J in alphabetic order. Sind has the caps in the top rows, in the old style, and Stellar Press put the X row above the A row. Oxford University Press put i where h is, h where s is, s where r is, and r where y is.

Variations in minor characters are numerous, but of the 29 lays, some more common agreements are:
the box above i is used for mids by 11, mids+thins by 4, thins by 4, v by 3, thicks by 1, ens by 1, y by 1, p by 1, g by 1, ' ' by 1, and ; by 1
