This field shows (usually) the width of the selected frame while it is being drawn or having its size altered.
Double-clicking on the field brings up a dialog for entering more precise values from the keyboard. You can terminate the input of numbers and formulae with [Return] or [Enter]. As with all Calamus dialogs they may be closed with [Undo], in which case any alteration or input of values are discarded.
In various modules which use the coordinate display for their output, both values and units can be different from the Frame editing module.
