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 ZS30 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 ZS30 has external dimensions of 105 x 59 x 28 mm (4.13 x 2.32 x 1.1″) and weighs 198 g (0.44 lb / 6.98 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G9 X and the Panasonic ZS30. Canon G9 X is 7mm narrower and 1mm shorter than Panasonic ZS30 but it is also 3mm thicker.
Here is the back view size comparison of the Canon G9 X and Panasonic ZS30.
Now lets look at the top view comparison of Canon G9 X and Panasonic ZS30.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS30 is 11g lighter than the Canon G9 X but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G9 X nor Panasonic Lumix DMC-ZS30 (Lumix DMC-TZ40) 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 ZS30's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
