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 A900 and Canon SX720 HS side-by-side from the front, back and top in their relative dimensions. Nikon A900 has external dimensions of 113 x 67 x 40 mm (4.45 x 2.64 x 1.57″) and weighs 289 g (0.64 lb / 10.19 oz) (including batteries). Canon SX720 HS has external dimensions of 110 x 64 x 36 mm (4.33 x 2.52 x 1.42″) and weighs 270 g (0.60 lb / 9.52 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A900 and the Canon SX720 HS. Canon SX720 HS is clearly the smaller of the two cameras. Its body is 3mm narrower, 3mm shorter and 4mm thinner than Nikon A900.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX720 HS is 19g lighter than the Nikon A900 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix A900 nor Canon PowerShot SX720 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
Nikon A900 and Canon SX720 HS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon A900 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 SX720 HS has a fixed type screen which provides less flexibility in shooting positions compared to A900.
