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 Casio EX-Z450 and Canon G1 X side-by-side from the front, back and top in their relative dimensions. Casio EX-Z450 has external dimensions of 81 x 56 x 21 mm (3.19 x 2.2 x 0.83″) and weighs 128 g (0.28 lb / 4.52 oz) (including batteries). Canon G1 X has external dimensions of 117 x 81 x 65 mm (4.61 x 3.19 x 2.56″) and weighs 534 g (1.18 lb / 18.84 oz) (including batteries).
Below you can see the front view size comparison of Casio EX-Z450 and Canon G1 X. Casio EX-Z450 is clearly the smaller of the two cameras. Its body is 36mm narrower, 25mm shorter and 44mm thinner than Canon G1 X.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Casio EX-Z450 is significantly lighter (406g ) than the Canon G1 X which may become a big advantage especially on long walking trips.
Unfortunately neither Casio Exilim EX-Z450 nor Canon PowerShot G1 X 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
Casio EX-Z450 and Canon G1 X's LCD screens has the same diagonal size of 3".
On the other hand, Canon G1 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. Casio EX-Z450's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G1 X.
