It depends on what you are planning to do (and why).
From my point of view, I would simply use the GimpZoomPreview widget.
This would adopt to the images aspect ratio and you can also see the
whole image with it as well as zoom into a specific subregion.
If you just want the aspect ratio to be the same, you could look at the code
for the zoom-preview widget and see how it does that trick.
