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 P310 and Canon S120 side-by-side from the front, back and top in their relative dimensions. 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). Canon S120 has external dimensions of 100 x 59 x 29 mm (3.94 x 2.32 x 1.14″) and weighs 217 g (0.48 lb / 7.65 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P310 and the Canon S120. Canon S120 is 3mm narrower and 3mm thinner than Nikon P310 but it is also 1mm taller.
Here is the back view size comparison of the Nikon P310 and Canon S120.
Now lets look at the top view comparison of Nikon P310 and Canon S120.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P310 is 23g lighter than the Canon S120 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix P310 nor Canon PowerShot S120 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 P310 and Canon S120'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.
