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 Sony W830 and Canon Elph 115 IS side-by-side from the front, back and top in their relative dimensions. Sony W830 has external dimensions of 93 x 52 x 23 mm (3.66 x 2.05 x 0.91″) and weighs 122 g (0.27 lb / 4.30 oz) (including batteries). Canon Elph 115 IS has external dimensions of 93 x 57 x 20 mm (3.66 x 2.24 x 0.79″) and weighs 135 g (0.30 lb / 4.76 oz) (including batteries).

Here is the back view size comparison of the Sony W830 and Canon Elph 115 IS.
Now lets look at the top view comparison of Sony W830 and Canon Elph 115 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W830 is 13g lighter than the Canon Elph 115 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W830 nor Canon Elph 115 IS (IXUS 132 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 115 IS's 3.00" LCD screen is slightly larger than Sony W830's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
