Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon G5 X and Sony H300 side-by-side from the front, back and top in their relative dimensions. Canon G5 X has external dimensions of 112 x 76 x 44 mm (4.41 x 2.99 x 1.73″) and weighs 353 g (0.78 lb / 12.45 oz) (including batteries).

Below you can see the front view size comparison of Canon G5 X and Sony H300. Canon G5 X is clearly the smaller of the two cameras. Its body is 18mm narrower, 19mm shorter and 78mm thinner than Sony H300.
Here is the back view size comparison of Canon G5 X and Sony H300.
Now lets look at the top view comparison of Canon G5 X and Sony H300.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G5 X is significantly lighter (237g ) than the Sony H300 which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot G5 X nor Sony Cyber-shot DSC-H300 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G5 X and Sony H300's LCD screens has the same diagonal size of 3".
On the other hand, Canon G5 X sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Sony H300's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G5 X.
