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 Samsung NX20 and Nikon P310 side-by-side from the front, back and top in their relative dimensions. Samsung NX20 has external dimensions of 122 x 90 x 40 mm (4.8 x 3.54 x 1.57″) and weighs 341 g (0.75 lb / 12.03 oz) (including batteries). Nikon P310 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 194 g (0.43 lb / 6.84 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung NX20 and the Nikon P310. Nikon P310 is clearly the smaller of the two cameras. Its body is 19mm narrower, 32mm shorter and 8mm thinner than Samsung NX20. As you can tell, actually this is not a fair size comparison since Nikon P310 has a built-in lens but Samsung NX20 doesn't. Once you put a lens on NX20, its thickness will increase significantly.
Here is the back view size comparison of the Samsung NX20 and Nikon P310.
Now lets look at the top view comparison of Samsung NX20 and Nikon P310.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P310 is significantly lighter (147g ) than the Samsung NX20 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 NX20, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Samsung NX20 nor Nikon Coolpix P310 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
Samsung NX20 and Nikon P310's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Samsung NX20 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Nikon P310's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to NX20.
