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 SD940 IS and Nikon S6900 side-by-side from the front, back and top in their relative dimensions. Canon SD940 IS has external dimensions of 89 x 55 x 20 mm (3.5 x 2.17 x 0.79″) and weighs 120 g (0.26 lb / 4.23 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 the Canon SD940 IS and the Nikon S6900. Canon SD940 IS is clearly the smaller of the two cameras. Its body is 10mm narrower, 3mm shorter and 8mm thinner than Nikon S6900.
Here is the back view size comparison of the Canon SD940 IS and Nikon S6900.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SD940 IS is significantly lighter (61g ) than the Nikon S6900 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot SD940 IS / Digital IXUS 120 IS 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 Canon SD940 IS'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 SD940 IS has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
