Method
ratio = width/GCD : height/GCD.
Reduce width and height to an integer ratio and detect orientation.
ratio = width/GCD : height/GCD.
Use the result as a transparent planning estimate. Change one assumption at a time, compare scenarios and move to Toolkit when you need system-level simulation.
Equivalent ratios can have very different resolutions and quality.
