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 ELPH 340 HS and Nikon S6400 side-by-side from the front, back and top in their relative dimensions. 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). Nikon S6400 has external dimensions of 95 x 58 x 27 mm (3.74 x 2.28 x 1.06″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 340 HS and the Nikon S6400.
Here is the back view size comparison of the Canon ELPH 340 HS and Nikon S6400.
Now lets look at the top view comparison of Canon ELPH 340 HS and Nikon S6400.
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 3g lighter than the Nikon S6400 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 340 HS (IXUS 265 HS) nor Nikon Coolpix S6400 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
Canon ELPH 340 HS and Nikon S6400's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
