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 Sony W810 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). Sony W810 has external dimensions of 97 x 56 x 21 mm (3.82 x 2.2 x 0.83″) and weighs 111 g (0.24 lb / 3.92 oz) (including batteries).
Below you can see the front-view size comparison of the Sony W800 and the Sony W810.
Here is the back view size comparison of the Sony W800 and Sony W810.
Now lets look at the top view comparison of Sony W800 and Sony W810.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W810 is 14g lighter than the Sony W800 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W800 nor Sony Cyber-shot DSC-W810 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 W800 and Sony W810's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
