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 Pentax VS20 and Olympus XZ-10 side-by-side from the front, back and top in their relative dimensions. Pentax VS20 has external dimensions of 111 x 61 x 38 mm (4.37 x 2.4 x 1.5″) and weighs 235 g (0.52 lb / 8.29 oz) (including batteries). Olympus XZ-10 has external dimensions of 102 x 61 x 34 mm (4.03 x 2.41 x 1.35″) and weighs 221 g (0.49 lb / 7.80 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax VS20 and the Olympus XZ-10. Pentax VS20 has the same height with Olympus XZ-10. On the other hand, with a width of 111mm, it is 9 wider and also with a thickness of 38mm, it is 4mm thicker than Olympus XZ-10.
Here is the back view size comparison of the Pentax VS20 and Olympus XZ-10.
Now lets look at the top view comparison of Pentax VS20 and Olympus XZ-10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus XZ-10 is 14g lighter than the Pentax VS20 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Pentax Optio VS20 nor Olympus Stylus XZ-10 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Pentax VS20 and Olympus XZ-10's LCD screens have the same diagonal size of 3.00 inches.
