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 TX100V 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 TX100V has external dimensions of 97 x 59 x 18 mm (3.82 x 2.32 x 0.71″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Sony TX20 and the Sony TX100V.
Here is the back view size comparison of the Sony TX20 and Sony TX100V.
Now lets look at the top view comparison of Sony TX20 and Sony TX100V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX20 is 14g lighter than the Sony TX100V 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 TX100V which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX100V's 3.50" LCD screen is slightly larger than Sony TX20's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
