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 TX55 and Sony WX220 side-by-side from the front, back and top in their relative dimensions. 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). Sony WX220 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries).
Below you can see the front-view size comparison of the Sony TX55 and the Sony WX220. Sony WX220 is 1mm narrower and 2mm shorter than Sony TX55 but it is also 9mm thicker.
Here is the back view size comparison of the Sony TX55 and Sony WX220.
Now lets look at the top view comparison of Sony TX55 and Sony WX220.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX55 is 12g lighter than the Sony WX220 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-TX55 nor Sony Cyber-shot DSC-WX220 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 TX55's 3.30" LCD screen is slightly larger than Sony WX220's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
