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 Nikon S6100 and Sony QX10 side-by-side from the front, back and top in their relative dimensions. Nikon S6100 has external dimensions of 98 x 58 x 27 mm (3.86 x 2.28 x 1.06″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries). Sony QX10 has external dimensions of 62 x 62 x 33 mm (2.46 x 2.43 x 1.31″) and weighs 105 g (0.23 lb / 3.70 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6100 and the Sony QX10. Nikon S6100 is 4mm shorter and 6mm thinner than Sony QX10 but it is also 36mm wider.
Here is the back view size comparison of the Nikon S6100 and Sony QX10.
Now lets look at the top view comparison of Nikon S6100 and Sony QX10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony QX10 is significantly lighter (70g ) than the Nikon S6100 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S6100 nor Sony Cyber-shot DSC-QX10 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
Nikon S6100's 3.00" LCD screen is slightly larger than Sony QX10's screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
