You can change the size of time signatures in each layout independently, including changing their vertical position. For example, you can show large time signatures centered on each bracket in full score layouts but standard-sized time signatures on each staff in part layouts.
Procedure
Result
The size and position of time signatures in the selected layouts is changed.
Showing large time signatures above the staff at system object positions means they do not occupy any rhythmic or horizontal space, whereas the other options do cause time signatures to occupy horizontal space.
After Completing This Task
You can change whether large time signatures are placed vertically in the middle or on the top of bracketed groups on the Time Signatures page in Engraving Options.
