You know you want to scale an object (text frame, graphic frame, path, or group) to a particular width or height, but what percentage should you type in the X% or Y% fields of the Control panel to achieve that size?
It�s easy: replace the 100% in one of those fields with an absolute value � the size you want it to be. For example, if you type 10cm, InDesign will do the math for you, figuring out what percentage it should scale the object(s).
