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 Canon IXUS 165 and Nikon S6900 side-by-side from the front, back and top in their relative dimensions. Canon IXUS 165 has external dimensions of 95 x 54 x 22 mm (3.74 x 2.13 x 0.87″) and weighs 128 g (0.28 lb / 4.52 oz) (including batteries). Nikon S6900 has external dimensions of 99 x 58 x 28 mm (3.9 x 2.28 x 1.1″) and weighs 181 g (0.40 lb / 6.38 oz) (including batteries).
Below you can see the front view size comparison of Canon IXUS 165 and Nikon S6900. Canon IXUS 165 is clearly the smaller of the two cameras. Its body is 4mm narrower, 4mm shorter and 6mm thinner than Nikon S6900.
Here is the back view size comparison of Canon IXUS 165 and Nikon S6900.
Now lets look at the top view comparison of Canon IXUS 165 and Nikon S6900.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon IXUS 165 is significantly lighter (53g ) than the Nikon S6900 which may become a big advantage especially on long walking trips.
Unfortunately neither Canon IXUS 165 nor Nikon Coolpix S6900 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
Nikon S6900's 3" LCD screen is slightly larger than Canon IXUS 165'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, Canon IXUS 165 has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
