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 Panasonic ZS45 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). Panasonic ZS45 has external dimensions of 108 x 60 x 32 mm (4.25 x 2.36 x 1.26″) and weighs 249 g (0.55 lb / 8.78 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G9 X and the Panasonic ZS45. Canon G9 X is clearly the smaller of the two cameras. Its body is 10mm narrower, 2mm shorter and 1mm thinner than Panasonic ZS45.
Here is the back view size comparison of the Canon G9 X and Panasonic ZS45.
Now lets look at the top view comparison of Canon G9 X and Panasonic ZS45.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G9 X is significantly lighter (40g ) than the Panasonic ZS45 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot G9 X nor Panasonic Lumix DMC-ZS45 (Lumix DMC-TZ57) 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 and Panasonic ZS45's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic ZS45 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 has a fixed type screen which provides less flexibility in shooting positions compared to ZS45.
