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 Panasonic ZS40 and Canon SX710 HS side-by-side from the front, back and top in their relative dimensions. Panasonic ZS40 has external dimensions of 111 x 64 x 34 mm (4.37 x 2.52 x 1.34″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic ZS40 and the Canon SX710 HS. Panasonic ZS40 is clearly the smaller of the two cameras. Its body is 2mm narrower, 2mm shorter and 1mm thinner than Canon SX710 HS.
Here is the back view size comparison of the Panasonic ZS40 and Canon SX710 HS.
Now lets look at the top view comparison of Panasonic ZS40 and Canon SX710 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS40 is 29g lighter than the Canon SX710 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) nor Canon PowerShot SX710 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
Panasonic ZS40 and Canon SX710 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.
