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 SX710 HS and Canon SX720 HS side-by-side from the front, back and top in their relative dimensions. Canon SX710 HS has external dimensions of 113 x 66 x 35 mm (4.45 x 2.6 x 1.38″) and weighs 269 g (0.59 lb / 9.49 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 Canon SX710 HS and the Canon SX720 HS. Canon SX720 HS is 3mm narrower and 2mm shorter than Canon SX710 HS but it is also 1mm thicker.
Here is the back view size comparison of the Canon SX710 HS and Canon SX720 HS.
Now lets look at the top view comparison of Canon SX710 HS and Canon SX720 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX710 HS is 1g lighter than the Canon SX720 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot SX710 HS 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. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Canon SX710 HS and Canon SX720 HS's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
