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 TX55 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 TX55 has external dimensions of 93 x 54 x 13 mm (3.66 x 2.13 x 0.51″) and weighs 109 g (0.24 lb / 3.84 oz) (including batteries).
Below you can see the front-view size comparison of the Sony TX20 and the Sony TX55. Sony TX55 is clearly the smaller of the two cameras. Its body is 3mm narrower, 2mm shorter and 5mm thinner than Sony TX20.
Here is the back view size comparison of the Sony TX20 and Sony TX55.
Now lets look at the top view comparison of Sony TX20 and Sony TX55.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX55 is significantly lighter (24g ) 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 TX55 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX55's 3.30" 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.
