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 ELPH 150 IS and Sony WX150 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). Sony WX150 has external dimensions of 95 x 56 x 22 mm (3.74 x 2.2 x 0.87″) and weighs 133 g (0.29 lb / 4.69 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 150 IS and the Sony WX150.
Here is the back view size comparison of the Canon ELPH 150 IS and Sony WX150.
Now lets look at the top view comparison of Canon ELPH 150 IS and Sony WX150.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony WX150 is 9g lighter than the Canon ELPH 150 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 150 IS (IXUS 155) nor Sony Cyber-shot DSC-WX150 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
Sony WX150's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
