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 L120 and Canon ELPH 510 HS side-by-side from the front, back and top in their relative dimensions. Nikon L120 has external dimensions of 110 x 77 x 78 mm (4.33 x 3.03 x 3.07″) and weighs 431 g (0.95 lb / 15.20 oz) (including batteries).

Now lets look at the top view comparison of Nikon L120 and Canon ELPH 510 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 510 HS is significantly lighter (225g ) than the Nikon L120 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix L120 nor Canon ELPH 510 HS (IXUS 1100 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 510 HS's 3.20" LCD screen is slightly larger than Nikon L120's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
