The design area is controlled by the selection system of the machine:
Full jacquard implies unrestricted pattern depth in pattern rows and a width that may be the total number of needles in the machine.
Large area jacquard designs have a pattern depth that requires more than one machine revolution to be developed and therefore each feeder contributes two or more courses; the pattern width is usually more than 48 wales.
Small area jacquard has a pattern depth which is developed in one machine revolution so that each feeder contributes only one course from a fixed selection, and the pattern width is 48 wales or less.
