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 S9100 and Canon S110 side-by-side from the front, back and top in their relative dimensions. Nikon S9100 has external dimensions of 105 x 62 x 35 mm (4.13 x 2.44 x 1.38″) and weighs 214 g (0.47 lb / 7.55 oz) (including batteries). Canon S110 has external dimensions of 99 x 59 x 27 mm (3.9 x 2.32 x 1.06″) and weighs 198 g (0.44 lb / 6.98 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S9100 and the Canon S110. Canon S110 is clearly the smaller of the two cameras. Its body is 6mm narrower, 3mm shorter and 8mm thinner than Nikon S9100.
Here is the back view size comparison of the Nikon S9100 and Canon S110.
Now lets look at the top view comparison of Nikon S9100 and Canon S110.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon S110 is 16g lighter than the Nikon S9100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S9100 nor Canon PowerShot S110 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 S9100 and Canon S110's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
