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 W690 and Sony W800 side-by-side from the front, back and top in their relative dimensions. Sony W690 has external dimensions of 94 x 56 x 22 mm (3.7 x 2.2 x 0.87″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Sony W690 and the Sony W800. Sony W800 is 1mm shorter and 1mm thinner than Sony W690 but it is also 3mm wider.
Here is the back view size comparison of the Sony W690 and Sony W800.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W800 is 17g lighter than the Sony W690 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W690 nor Sony Cyber-shot DSC-W800 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 W690'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.
