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 L810 and Nikon L820 side-by-side from the front, back and top in their relative dimensions. Nikon L810 has external dimensions of 111 x 76 x 83 mm (4.37 x 2.99 x 3.27″) and weighs 430 g (0.95 lb / 15.17 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 L810 and the Nikon L820. Nikon L810 has the same height and width with Nikon L820. On the other hand, with a thickness of 83mm, it is 2mm thinner.
Here is the back view size comparison of the Nikon L810 and Nikon L820.
Now lets look at the top view comparison of Nikon L810 and Nikon L820.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L810 is 40g lighter than the Nikon L820 but we don't think this will make a significant difference.
