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 Casio EX-S200 and Canon ELPH 340 HS side-by-side from the front, back and top in their relative dimensions. Casio EX-S200 has external dimensions of 100 x 55 x 18 mm (3.94 x 2.17 x 0.71″) and weighs 132 g (0.29 lb / 4.66 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 Casio EX-S200 and the Canon ELPH 340 HS. Casio EX-S200 has the same height with Canon ELPH 340 HS. On the other hand, with a width of 55mm, it is 3 narrower and also with a thickness of 18mm, it is 4mm thinner than Canon ELPH 340 HS.
Here is the back view size comparison of the Casio EX-S200 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.
Casio EX-S200 is 15g lighter than the Canon ELPH 340 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Casio Exilim EX-S200 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 ELPH 340 HS's 3.00" LCD screen is slightly larger than Casio EX-S200's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
