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 Nikon S3700 and Nikon S6900 side-by-side from the front, back and top in their relative dimensions. 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 Nikon S3700 and the Nikon S6900. Nikon S3700 is 3mm narrower and 8mm thinner than Nikon S3700 but they have the same height of 58mm.
Here is the back view size comparison of the Nikon S3700 and Nikon S6900.
Now lets look at the top view comparison of Nikon S3700 and Nikon S6900.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S3700 is significantly lighter (63g ) than the Nikon S6900 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S3700 nor Nikon Coolpix S6900 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 S6900's 3.00" LCD screen is slightly larger than Nikon S3700's 2.7 screen.
Moreover, Nikon S6900 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 S3700 has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
