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 G9 X and Sony TX100V side-by-side from the front, back and top in their relative dimensions. Canon G9 X has external dimensions of 98 x 58 x 31 mm (3.86 x 2.28 x 1.21″) and weighs 209 g (0.46 lb / 7.37 oz) (including batteries).

Now lets look at the top view comparison of Canon G9 X and Sony TX100V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX100V is significantly lighter (62g ) than the Canon G9 X which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot G9 X nor Sony Cyber-shot DSC-TX100V 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
Sony TX100V's 3.50" LCD screen is slightly larger than Canon G9 X's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
