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 Sony WX1 and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Sony WX1 has external dimensions of 91 x 52 x 20 mm (3.58 x 2.05 x 0.79″) and weighs 149 g (0.33 lb / 5.26 oz) (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 Sony WX1 and the Nikon P7800. Sony WX1 is clearly the smaller of the two cameras. Its body is 28mm narrower, 26mm shorter and 30mm thinner than Nikon P7800.
Here is the back view size comparison of the Sony WX1 and Nikon P7800.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony WX1 is significantly lighter (250g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX1 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 Sony WX1's 2.7" 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, Sony WX1 has a fixed type screen which provides almost no flexibility in shooting positions compared to P7800.
