Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Sony WX30 and Sony W800 side-by-side from the front, back and top in their relative dimensions. Sony WX30 has external dimensions of 92 x 52 x 19 mm (3.62 x 2.05 x 0.75″) and weighs 117 g (0.26 lb / 4.13 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 Sony WX30 and Sony W800. Sony WX30 is clearly the smaller of the two cameras. Its body is 5mm narrower, 3mm shorter and 2mm thinner than Sony W800.
Now lets look at the top view comparison of Sony WX30 and Sony W800.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony WX30 is 8g lighter than the Sony W800 but we don't think this will make a significant difference.
Unfortunately neither Sony Cyber-shot DSC-WX30 nor Sony Cyber-shot DSC-W800 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Sony WX30's 3" LCD screen is slightly larger than Sony W800's 2.7" screen.
