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 TX66 and Samsung ST95 side-by-side from the front, back and top in their relative dimensions. Sony TX66 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). Samsung ST95 has external dimensions of 92 x 53 x 17 mm (3.62 x 2.09 x 0.67″) and weighs (including batteries).
Below you can see the front-view size comparison of the Sony TX66 and the Samsung ST95. Samsung ST95 is 1mm narrower and 1mm shorter than Sony TX66 but it is also 4mm thicker.
Here is the back view size comparison of the Sony TX66 and Samsung ST95.
Now lets look at the top view comparison of Sony TX66 and Samsung ST95.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung ST95 is 109g lighter than the Sony TX66 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-TX66 nor Samsung ST95 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 TX66's 3.30" LCD screen is slightly larger than Samsung ST95's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
