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 Nikon S9300 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). Nikon S9300 has external dimensions of 109 x 62 x 31 mm (4.29 x 2.44 x 1.22″) and weighs 215 g (0.47 lb / 7.58 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Q10 and the Nikon S9300. Pentax Q10 is 7mm narrower and 4mm shorter than Nikon S9300 but it is also 3mm thicker. As you can tell, actually this is not a fair size comparison since Nikon S9300 has a built-in lens but Pentax Q10 doesn't. Once you put a lens on Q10, its thickness will increase significantly.
Here is the back view size comparison of the Pentax Q10 and Nikon S9300.
Now lets look at the top view comparison of Pentax Q10 and Nikon S9300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Q10 is 15g lighter than the Nikon S9300 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 Nikon Coolpix S9300 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 Nikon S9300'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.
