Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon L31 and Panasonic FZ150 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Panasonic FZ150 has external dimensions of 124 x 82 x 92 mm (4.88 x 3.23 x 3.62″) and weighs 528 g (1.16 lb / 18.62 oz) (including batteries).
Below you can see the front view size comparison of Nikon L31 and Panasonic FZ150. Nikon L31 is clearly the smaller of the two cameras. Its body is 28mm narrower, 23mm shorter and 63mm thinner than Panasonic FZ150.
Here is the back view size comparison of Nikon L31 and Panasonic FZ150.
Now lets look at the top view comparison of Nikon L31 and Panasonic FZ150.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (368g ) than the Panasonic FZ150 which may become a big advantage especially on long walking trips.
Unfortunately neither Nikon Coolpix L31 nor Panasonic Lumix DMC-FZ150 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic FZ150's 3" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Moreover, Panasonic FZ150 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, Nikon L31 has a fixed type screen which provides almost no flexibility in shooting positions compared to FZ150.
