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 L840 and Nikon L820 side-by-side from the front, back and top in their relative dimensions. Nikon L840 has external dimensions of 114 x 89 x 96 mm (4.49 x 3.5 x 3.78″) and weighs 538 g (1.19 lb / 18.98 oz) (including batteries). Nikon L820 has external dimensions of 111 x 76 x 85 mm (4.37 x 2.99 x 3.35″) and weighs 470 g (1.04 lb / 16.58 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L840 and the Nikon L820. Nikon L820 is clearly the smaller of the two cameras. Its body is 3mm narrower, 13mm shorter and 11mm thinner than Nikon L840.
Here is the back view size comparison of the Nikon L840 and Nikon L820.
Now lets look at the top view comparison of Nikon L840 and Nikon L820.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L820 is 68g lighter than the Nikon L840 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix L840 nor Nikon Coolpix L820 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 L840 and Nikon L820's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon L840 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 L820 has a fixed type screen which provides less flexibility in shooting positions compared to L840.
