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 S6900 and Canon ELPH 340 HS side-by-side from the front, back and top in their relative dimensions. 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). Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).

Here is the back view size comparison of Nikon S6900 and Canon ELPH 340 HS.
Now lets look at the top view comparison of Nikon S6900 and Canon ELPH 340 HS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 340 HS is significantly lighter (34g ) than the Nikon S6900 which may become a big advantage especially on long walking trips.
Unfortunately neither Nikon Coolpix S6900 nor Canon PowerShot ELPH 340 HS (IXUS 265 HS) 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 and Canon ELPH 340 HS's LCD screens has the same diagonal size of 3".
On the other hand, 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. Canon ELPH 340 HS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S6900.
