Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon L31 and Samsung NX11 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Samsung NX11 has external dimensions of 123 x 87 x 40 mm (4.84 x 3.43 x 1.57″) and weighs 499 g (1.10 lb / 17.60 oz) (including batteries).
Below you can see the front view size comparison of Nikon L31 and Samsung NX11. Nikon L31 is clearly the smaller of the two cameras. Its body is 27mm narrower, 28mm shorter and 11mm thinner than Samsung NX11. As you can tell, actually this is not a fair size comparison since Nikon L31 has a built-in lens but Samsung NX11 doesn't. Once you put a lens on NX11, 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.
Nikon L31 is significantly lighter (339g ) than the Samsung NX11 which may become a big advantage especially on long walking trips.
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 NX11, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix L31 nor Samsung NX11 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung NX11's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
