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 Panasonic GF8 and Canon G9 X II side-by-side from the front, back and top in their relative dimensions. Panasonic GF8 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries). Canon G9 X II has external dimensions of 98 x 58 x 31 mm (3.86 x 2.28 x 1.22″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GF8 and the Canon G9 X II. Canon G9 X II is clearly the smaller of the two cameras. Its body is 9mm narrower, 7mm shorter and 2mm thinner than Panasonic GF8. As you can tell, actually this is not a fair size comparison since Canon G9 X II has a built-in lens but Panasonic GF8 doesn't. Once you put a lens on GF8, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic GF8 and Canon G9 X II.
Now lets look at the top view comparison of Panasonic GF8 and Canon G9 X II.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G9 X II is significantly lighter (60g ) than the Panasonic GF8 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on GF8, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-GF8 nor Canon PowerShot G9 X Mark II 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
Panasonic GF8 and Canon G9 X II's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GF8 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon G9 X II has a fixed type screen which provides less flexibility in shooting positions compared to GF8.
