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 TX20 and Sony W830 side-by-side from the front, back and top in their relative dimensions. Sony TX20 has external dimensions of 96 x 56 x 18 mm (3.78 x 2.2 x 0.71″) and weighs 133 g (0.29 lb / 4.69 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 TX20 and the Sony W830. Sony W830 is 3mm narrower and 4mm shorter than Sony TX20 but it is also 5mm thicker.
Here is the back view size comparison of the Sony TX20 and Sony W830.
Now lets look at the top view comparison of Sony TX20 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 11g lighter than the Sony TX20 but we don't think this will make a significant difference.
Weather Sealing
With its weather-sealed body, we believe that the TX20 has a big advantage over the W830 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX20'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.
