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 WX80 and Sony W830 side-by-side from the front, back and top in their relative dimensions. Sony WX80 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 124 g (0.27 lb / 4.37 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Sony WX80 and the Sony W830. Sony WX80 is 1mm narrower and 1mm thinner than Sony WX80 but they have the same height of 52mm.
Here is the back view size comparison of the Sony WX80 and Sony W830.
Now lets look at the top view comparison of Sony WX80 and Sony W830.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W830 is 2g lighter than the Sony WX80 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX80 nor Sony Cyber-shot DSC-W830 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Sony WX80 and Sony W830's LCD screens have the same diagonal size of 2.70 inches.
