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 A100 and Canon ELPH 180 side-by-side from the front, back and top in their relative dimensions. Nikon A100 has external dimensions of 95 x 59 x 20 mm (3.74 x 2.32 x 0.79″) and weighs 119 g (0.26 lb / 4.20 oz) (including batteries). Canon ELPH 180 has external dimensions of 95 x 54 x 22 mm (3.74 x 2.13 x 0.87″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).

Here is the back view size comparison of the Nikon A100 and Canon ELPH 180.
Now lets look at the top view comparison of Nikon A100 and Canon ELPH 180.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A100 is 7g lighter than the Canon ELPH 180 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix A100 nor Canon PowerShot ELPH 180 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 A100 and Canon ELPH 180's LCD screens have the same diagonal size of 2.70 inches.
