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 Casio EX-ZS10 and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Casio EX-ZS10 has external dimensions of 103 x 59 x 20 mm (4.06 x 2.32 x 0.79″) and weighs (including batteries). 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).
Below you can see the front-view size comparison of the Casio EX-ZS10 and the Nikon P7800. Casio EX-ZS10 is clearly the smaller of the two cameras. Its body is 16mm narrower, 19mm shorter and 30mm thinner than Nikon P7800.
Here is the back view size comparison of the Casio EX-ZS10 and Nikon P7800.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-ZS10 is 399g lighter than the Nikon P7800 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Casio Exilim EX-ZS10 nor Nikon Coolpix P7800 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's 3.00" LCD screen is slightly larger than Casio EX-ZS10's screen.
Moreover, 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. On the other hand, Casio EX-ZS10 has a fixed type screen which provides almost no flexibility in shooting positions compared to P7800.
