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 L31 and Canon ELPH 500 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).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is 25g lighter than the Canon ELPH 500 HS but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix L31 nor Canon ELPH 500 HS (IXUS 310 HS / IXY 31S) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Canon ELPH 500 HS's 3.20" LCD screen is slightly larger than Nikon L31's 2.7" screen.
