Assuming that you are talking about a relatively small change:

The reason for this is that a rectangle with a stroke is based on a set of infinetely small lines (red), which are then equipped with a stroke (black) such that those lines are in the middle of the stroke.



If you increase the size of the stroke, the position of the lines (red) is fixed and thus you also slightly increase the size of the total object (by half the increase of the stroke width).

I am not aware of a way to directly prevent this, but you can manually reset the size of the rectangle after changing the stroke width. The easiest way to do this is as follows:


Select the rectangle.
Copy it (Ctrl + C).
Change the stroke width.
Paste → Paste Size (if you care about preserving the size to the last digit, you may have to repeat this once or twice).
