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 Panasonic FZ80 and Nikon P900 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ80 has external dimensions of 130 x 94 x 119 mm (5.12 x 3.7 x 4.69″) and weighs 616 g (1.36 lb / 21.73 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 Panasonic FZ80 and the Nikon P900. Panasonic FZ80 is clearly the smaller of the two cameras. Its body is 10mm narrower, 9mm shorter and 18mm thinner than Nikon P900.
Here is the back view size comparison of the Panasonic FZ80 and Nikon P900.
Now lets look at the top view comparison of Panasonic FZ80 and Nikon P900.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FZ80 is significantly lighter (283g ) than the Nikon P900 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FZ80 (Lumix DMC-FZ82) 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
Panasonic FZ80 and Nikon P900's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P900 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. Panasonic FZ80's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P900.
