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 SX220 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 SX220 HS has external dimensions of 106 x 59 x 33 mm (4.17 x 2.32 x 1.3″) and weighs (including batteries).

Here is the back view size comparison of Nikon L31 and Canon SX220 HS.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX220 HS is 160g lighter than the Nikon L31 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix L31 nor Canon SX220 HS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Canon SX220 HS's 3" 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.
