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 340 HS and Sony WX80 side-by-side from the front, back and top in their relative dimensions. 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). Sony WX80 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 124 g (0.27 lb / 4.37 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 340 HS and the Sony WX80. Sony WX80 is 8mm narrower and 6mm shorter than Canon ELPH 340 HS but they have the same thickness of 22mm.
Here is the back view size comparison of the Canon ELPH 340 HS and Sony WX80.
Now lets look at the top view comparison of Canon ELPH 340 HS and Sony WX80.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony WX80 is significantly lighter (23g ) than the Canon ELPH 340 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 340 HS (IXUS 265 HS) nor Sony Cyber-shot DSC-WX80 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 ELPH 340 HS's 3.00" LCD screen is slightly larger than Sony WX80's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
