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 S9900 and Canon SX420 IS side-by-side from the front, back and top in their relative dimensions. Nikon S9900 has external dimensions of 112 x 66 x 40 mm (4.41 x 2.6 x 1.57″) and weighs 289 g (0.64 lb / 10.19 oz) (including batteries). Canon SX420 IS has external dimensions of 104 x 69 x 85 mm (4.09 x 2.72 x 3.35″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S9900 and the Canon SX420 IS. Nikon S9900 is 3mm shorter and 45mm thinner than Canon SX420 IS but it is also 8mm wider.
Here is the back view size comparison of the Nikon S9900 and Canon SX420 IS.
Now lets look at the top view comparison of Nikon S9900 and Canon SX420 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S9900 is 36g lighter than the Canon SX420 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S9900 nor Canon PowerShot SX420 IS 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
Nikon S9900 and Canon SX420 IS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon S9900 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Canon SX420 IS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S9900.
