Assuming the bases are to be ‘representative’, rather than exact numbers of troops? AFAIK they aimed at the time for a thousand man infantry regiment, one third pike, two thirds musket, but more commonly were half and half. Horse regiments were ideally 500 men and 500 horses, commonly with sword and pistols.
All pike or all musket regiments were possible, and just to make your life difficult, muskets could be stripped from regiments for tactical purposes. Armoured cavalry were rare.
Locals forming armed defence groups would have old military equipment, fowling pieces etc and seemed to be grouped in thousand man units.
Frontages for ideal units would have been similar. For my ‘One Hour Wargames’ ECW I produced 6” x 2” blocks of wood, adding symbols for horse, foot, clubmen and guns, with guns having a 2” front and 6” depth.
