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 A10 and Canon A810 side-by-side from the front, back and top in their relative dimensions. Nikon A10 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Canon A810 has external dimensions of 95 x 62 x 30 mm (3.74 x 2.44 x 1.18″) and weighs 171 g (0.38 lb / 6.03 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A10 and the Canon A810. Nikon A10 is 3mm shorter and 1mm thinner than Canon A810 but it is also 1mm wider.
Here is the back view size comparison of the Nikon A10 and Canon A810.
Now lets look at the top view comparison of Nikon A10 and Canon A810.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A10 is 11g lighter than the Canon A810 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix A10 nor Canon PowerShot A810 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 A10 and Canon A810's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
