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 P7800 and Panasonic LZ20 side-by-side from the front, back and top in their relative dimensions. Nikon P7800 has external dimensions of 119 x 78 x 50 mm (4.69 x 3.07 x 1.97″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries). Panasonic LZ20 has external dimensions of 120 x 76 x 80 mm (4.72 x 2.99 x 3.15″) and weighs 499 g (1.10 lb / 17.60 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P7800 and the Panasonic LZ20. Nikon P7800 is 1mm narrower and 30mm thinner than Panasonic LZ20 but it is also 2mm taller.
Here is the back view size comparison of the Nikon P7800 and Panasonic LZ20.
Now lets look at the top view comparison of Nikon P7800 and Panasonic LZ20.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P7800 is significantly lighter (100g ) than the Panasonic LZ20 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix P7800 nor Panasonic Lumix DMC-LZ20 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 P7800 and Panasonic LZ20'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. Panasonic LZ20's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7800.
