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 P300 and Olympus E-M10 side-by-side from the front, back and top in their relative dimensions. Nikon P300 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 189 g (0.42 lb / 6.67 oz) (including batteries). Olympus E-M10 has external dimensions of 119 x 82 x 46 mm (4.69 x 3.24 x 1.81″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front view size comparison of Nikon P300 and Olympus E-M10. Nikon P300 is clearly the smaller of the two cameras. Its body is 16mm narrower, 24mm shorter and 14mm thinner than Olympus E-M10. As you can tell, actually this is not a fair size comparison since Nikon P300 has a built-in lens but Olympus E-M10 doesn't. Once you put a lens on E-M10, 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 P300 is significantly lighter (207g ) than the Olympus E-M10 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, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix P300 nor Olympus OM-D E-M10 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
Nikon P300 and Olympus E-M10's LCD screens has the same diagonal size of 3".
On the other hand, Olympus E-M10 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Nikon P300 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10.
