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 Olympus XZ-10 and Nikon P310 side-by-side from the front, back and top in their relative dimensions. Olympus XZ-10 has external dimensions of 102 x 61 x 34 mm (4.03 x 2.41 x 1.35″) and weighs 221 g (0.49 lb / 7.80 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 Olympus XZ-10 and the Nikon P310. Nikon P310 is 3mm shorter and 2mm thinner than Olympus XZ-10 but it is also 1mm wider.
Here is the back view size comparison of the Olympus XZ-10 and Nikon P310.
Now lets look at the top view comparison of Olympus XZ-10 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 27g lighter than the Olympus XZ-10 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus Stylus XZ-10 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
Olympus XZ-10 and Nikon P310'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.
