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 Canon G16 and Nikon A1000 side-by-side from the front, back and top in their relative dimensions. Canon G16 has external dimensions of 109 x 76 x 40 mm (4.29 x 2.99 x 1.57″) and weighs 356 g (0.78 lb / 12.56 oz) (including batteries). Nikon A1000 has external dimensions of 114 x 72 x 41 mm (4.49 x 2.83 x 1.61″) and weighs 330 g (0.73 lb / 11.64 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G16 and the Nikon A1000. Canon G16 is 5mm narrower and 1mm thinner than Nikon A1000 but it is also 4mm taller.
Here is the back view size comparison of the Canon G16 and Nikon A1000.
Now lets look at the top view comparison of Canon G16 and Nikon A1000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A1000 is 26g lighter than the Canon G16 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G16 nor Nikon Coolpix A1000 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 G16 and Nikon A1000's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon A1000 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon G16 has a fixed type screen which provides less flexibility in shooting positions compared to A1000.
