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 WX300 and Sony W830 side-by-side from the front, back and top in their relative dimensions. Sony WX300 has external dimensions of 96 x 55 x 25 mm (3.78 x 2.16 x 0.98″) and weighs 166 g (0.37 lb / 5.86 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 WX300 and the Sony W830. Sony W830 is clearly the smaller of the two cameras. Its body is 3mm narrower, 3mm shorter and 2mm thinner than Sony WX300.
Now lets look at the top view comparison of Sony WX300 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 significantly lighter (44g ) than the Sony WX300 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX300 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.

LCD Screen Size and Features
Sony WX300's 3.00" LCD screen is slightly larger than Sony W830's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
