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 G16 and Nikon L19 side-by-side from the front, back and top in their relative dimensions. Canon G16 has external dimensions of 109 x 76 x 40 mm (4.29 x 2.99 x 1.57″) and weighs 356 g (0.78 lb / 12.56 oz) (including batteries). Nikon L19 has external dimensions of 61 x 97 x 29 mm (2.4 x 3.82 x 1.14″) and weighs 130 g (0.29 lb / 4.59 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L19 is significantly lighter (226g ) than the Canon G16 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot G16 nor Nikon Coolpix L19 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 G16's 3.00" LCD screen is slightly larger than Nikon L19's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
