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 170 IS 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 170 IS has external dimensions of 100 x 58 x 23 mm (3.94 x 2.28 x 0.91″) and weighs 141 g (0.31 lb / 4.97 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G5 X and the Canon 170 IS. Canon 170 IS is clearly the smaller of the two cameras. Its body is 12mm narrower, 18mm shorter and 21mm thinner than Canon G5 X.
Here is the back view size comparison of the Canon G5 X and Canon 170 IS.
Now lets look at the top view comparison of Canon G5 X and Canon 170 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon 170 IS is significantly lighter (212g ) 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 170 IS (IXUS 170) 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's 3.00" LCD screen is slightly larger than Canon 170 IS's 2.7 screen.
Moreover, 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. On the other hand, Canon 170 IS has a fixed type screen which provides almost no flexibility in shooting positions compared to G5 X.
