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 HX20V and Sony HX10V side-by-side from the front, back and top in their relative dimensions. Sony HX20V has external dimensions of 107 x 62 x 35 mm (4.21 x 2.44 x 1.38″) and weighs 254 g (0.56 lb / 8.96 oz) (including batteries). Sony HX10V has external dimensions of 105 x 60 x 34 mm (4.13 x 2.36 x 1.34″) and weighs 234 g (0.52 lb / 8.25 oz) (including batteries).
Below you can see the front-view size comparison of the Sony HX20V and the Sony HX10V. Sony HX10V is clearly the smaller of the two cameras. Its body is 2mm narrower, 2mm shorter and 1mm thinner than Sony HX20V.
Here is the back view size comparison of the Sony HX20V and Sony HX10V.
Now lets look at the top view comparison of Sony HX20V and Sony HX10V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony HX10V is 20g lighter than the Sony HX20V but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX20V nor Sony Cyber-shot DSC-HX10V 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 HX20V and Sony HX10V's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
