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 P310 and Canon A810 side-by-side from the front, back and top in their relative dimensions. Nikon P310 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 194 g (0.43 lb / 6.84 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).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A810 is 23g lighter than the Nikon P310 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix P310 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. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Nikon P310's 3.00" LCD screen is slightly larger than Canon A810's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
