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 G5 X and Canon ELPH 340 HS 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). Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G5 X and the Canon ELPH 340 HS. Canon ELPH 340 HS is clearly the smaller of the two cameras. Its body is 12mm narrower, 18mm shorter and 22mm thinner than Canon G5 X.
Here is the back view size comparison of the Canon G5 X and Canon ELPH 340 HS.
Now lets look at the top view comparison of Canon G5 X and Canon ELPH 340 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 340 HS is significantly lighter (206g ) than the Canon G5 X which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot G5 X nor Canon PowerShot ELPH 340 HS (IXUS 265 HS) 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 G5 X and Canon ELPH 340 HS's LCD screens have the same diagonal size of 3.00 inches.
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. Canon ELPH 340 HS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G5 X.
