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 ZS25 and Nikon L840 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS25 has external dimensions of 105 x 59 x 28 mm (4.13 x 2.32 x 1.1″) and weighs 193 g (0.43 lb / 6.81 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic ZS25 and the Nikon L840. Panasonic ZS25 is clearly the smaller of the two cameras. Its body is 9mm narrower, 30mm shorter and 68mm thinner than Nikon L840.
Here is the back view size comparison of the Panasonic ZS25 and Nikon L840.
Now lets look at the top view comparison of Panasonic ZS25 and Nikon L840.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS25 is significantly lighter (345g ) than the Nikon L840 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS25 (Lumix DMC-TZ35) nor Nikon Coolpix L840 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 ZS25 and Nikon L840'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 Panasonic ZS25 has a fixed type screen which provides less flexibility in shooting positions compared to L840.
