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 L31 and Canon ELPH 350 HS side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Canon ELPH 350 HS has external dimensions of 100 x 58 x 23 mm (3.94 x 2.28 x 0.91″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the Canon ELPH 350 HS. Canon ELPH 350 HS is 1mm shorter and 6mm thinner than Nikon L31 but it is also 4mm wider.
Here is the back view size comparison of the Nikon L31 and Canon ELPH 350 HS.
Now lets look at the top view comparison of Nikon L31 and Canon ELPH 350 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 350 HS is 13g lighter than the Nikon L31 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix L31 nor Canon PowerShot ELPH 350 HS (IXUS 275 HS) 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 350 HS's 3.00" LCD screen is slightly larger than Nikon L31's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
