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 SX730 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 SX730 HS has external dimensions of 110 x 64 x 40 mm (4.33 x 2.52 x 1.57″) and weighs 300 g (0.66 lb / 10.58 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A900 and the Canon SX730 HS. Canon SX730 HS is 3mm narrower and 3mm shorter than Nikon A900 but they have the same thickness of 40mm.
Here is the back view size comparison of the Nikon A900 and Canon SX730 HS.
Now lets look at the top view comparison of Nikon A900 and Canon SX730 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A900 is 11g lighter than the Canon SX730 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix A900 nor Canon PowerShot SX730 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Nikon A900 and Canon SX730 HS's LCD screens have the same diagonal size of 3.00 inches.
