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 WX220 and Nikon S3700 side-by-side from the front, back and top in their relative dimensions. Sony WX220 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries). Nikon S3700 has external dimensions of 96 x 58 x 20 mm (3.78 x 2.28 x 0.79″) and weighs 118 g (0.26 lb / 4.16 oz) (including batteries).
Below you can see the front-view size comparison of the Sony WX220 and the Nikon S3700. Sony WX220 is 4mm narrower and 6mm shorter than Nikon S3700 but it is also 2mm thicker.
Here is the back view size comparison of the Sony WX220 and Nikon S3700.
Now lets look at the top view comparison of Sony WX220 and Nikon S3700.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S3700 is 3g lighter than the Sony WX220 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX220 nor Nikon Coolpix S3700 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
Sony WX220's 3.00" LCD screen is slightly larger than Nikon S3700's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
