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 Q10 and Samsung WB250F side-by-side from the front, back and top in their relative dimensions. Pentax Q10 has external dimensions of 102 x 58 x 34 mm (4.02 x 2.28 x 1.34″) and weighs 200 g (0.44 lb / 7.05 oz) (including batteries). Samsung WB250F has external dimensions of 106 x 62 x 22 mm (4.17 x 2.44 x 0.87″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Q10 and the Samsung WB250F. Pentax Q10 is 4mm narrower and 4mm shorter than Samsung WB250F but it is also 12mm thicker. As you can tell, actually this is not a fair size comparison since Samsung WB250F has a built-in lens but Pentax Q10 doesn't. Once you put a lens on Q10, its thickness will increase significantly.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Q10 is 26g lighter than the Samsung WB250F but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on Q10, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Pentax Q10 nor Samsung WB250F 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
Pentax Q10 and Samsung WB250F'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.
