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 W810 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 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 TX20 and the Sony W810. Sony TX20 is 1mm narrower and 3mm thinner than Sony TX20 but they have the same height of 56mm.
Here is the back view size comparison of the Sony TX20 and Sony W810.
Now lets look at the top view comparison of Sony TX20 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 significantly lighter (22g ) than the Sony TX20 which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the TX20 has a big advantage over the W810 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 W810's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
