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 E-M10 II and Nikon P900 side-by-side from the front, back and top in their relative dimensions. Olympus E-M10 II has external dimensions of 120 x 83 x 47 mm (4.72 x 3.27 x 1.85″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries). Nikon P900 has external dimensions of 140 x 103 x 137 mm (5.51 x 4.06 x 5.39″) and weighs 899 g (1.98 lb / 31.71 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M10 II and the Nikon P900. Olympus E-M10 II is clearly the smaller of the two cameras. Its body is 20mm narrower, 20mm shorter and 90mm thinner than Nikon P900. As you can tell, actually this is not a fair size comparison since Nikon P900 has a built-in lens but Olympus E-M10 II doesn't. Once you put a lens on E-M10 II, its thickness will increase significantly.
Here is the back view size comparison of the Olympus E-M10 II and Nikon P900.
Now lets look at the top view comparison of Olympus E-M10 II and Nikon P900.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M10 II is significantly lighter (509g ) than the Nikon P900 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 E-M10 II, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Olympus OM-D E-M10 II nor Nikon Coolpix P900 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 E-M10 II and Nikon P900's LCD screens have the same diagonal size of 3.00 inches.
Olympus E-M10 II features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Nikon P900 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
