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 SX600 HS 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 SX600 HS has external dimensions of 104 x 61 x 26 mm (4.09 x 2.4 x 1.02″) and weighs 188 g (0.41 lb / 6.63 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A100 and the Canon SX600 HS. Nikon A100 is clearly the smaller of the two cameras. Its body is 9mm narrower, 2mm shorter and 6mm thinner than Canon SX600 HS.
Here is the back view size comparison of the Nikon A100 and Canon SX600 HS.
Now lets look at the top view comparison of Nikon A100 and Canon SX600 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A100 is significantly lighter (69g ) than the Canon SX600 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix A100 nor Canon PowerShot SX600 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 SX600 HS's 3.00" LCD screen is slightly larger than Nikon A100's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
