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 W800 and Canon A3500 IS side-by-side from the front, back and top in their relative dimensions. Sony W800 has external dimensions of 97 x 55 x 21 mm (1.97 x 0.87 x 2.13″) and weighs 125 g (0.28 lb / 4.41 oz) (including batteries). Canon A3500 IS has external dimensions of 98 x 56 x 20 mm (3.86 x 2.2 x 0.79″) and weighs 135 g (0.30 lb / 4.76 oz) (including batteries).
Below you can see the front-view size comparison of the Sony W800 and the Canon A3500 IS. Sony W800 is 1mm narrower and 1mm shorter than Canon A3500 IS but it is also 1mm thicker.
Now lets look at the top view comparison of Sony W800 and Canon A3500 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W800 is 10g lighter than the Canon A3500 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W800 nor Canon PowerShot A3500 IS 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 A3500 IS's 3.00" LCD screen is slightly larger than Sony W800's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
