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 Canon S120 and Sony W380 side-by-side from the front, back and top in their relative dimensions. Canon S120 has external dimensions of 100 x 59 x 29 mm (3.94 x 2.32 x 1.14″) and weighs 217 g (0.48 lb / 7.65 oz) (including batteries). Sony W380 has external dimensions of 91 x 52 x 20 mm (3.58 x 2.05 x 0.79″) and weighs 117 g (0.26 lb / 4.13 oz) (including batteries).
Below you can see the front-view size comparison of the Canon S120 and the Sony W380. Sony W380 is clearly the smaller of the two cameras. Its body is 9mm narrower, 7mm shorter and 9mm thinner than Canon S120.
Here is the back view size comparison of the Canon S120 and Sony W380.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W380 is significantly lighter (100g ) than the Canon S120 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot S120 nor Sony Cyber-shot DSC-W380 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
Canon S120's 3.00" LCD screen is slightly larger than Sony W380's 2.7" screen.
