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 P300 and Nikon P7800 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).

Here is the back view size comparison of the Nikon P300 and Nikon P7800.
Now lets look at the top view comparison of Nikon P300 and Nikon P7800.
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 (210g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix P300 nor Nikon Coolpix P7800 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 P300 and Nikon P7800's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P7800 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 P300's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7800.
