Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Canon IXUS 165 and Canon G9 X side-by-side from the front, back and top in their relative dimensions.

Now lets look at the top view comparison of Canon IXUS 165 and Canon G9 X.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Canon IXUS 165 nor Canon PowerShot G9 X provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G9 X's 3.00" LCD screen is slightly larger than Canon IXUS 165's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
