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 M5 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 M5 has external dimensions of 116 x 89 x 61 mm (4.57 x 3.5 x 2.4″) and weighs 427 g (0.94 lb / 15.06 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX710 HS and the Canon M5. Canon SX710 HS is clearly the smaller of the two cameras. Its body is 3mm narrower, 23mm shorter and 26mm thinner than Canon M5. As you can tell, actually this is not a fair size comparison since Canon SX710 HS has a built-in lens but Canon M5 doesn't. Once you put a lens on M5, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX710 HS and Canon M5.
Now lets look at the top view comparison of Canon SX710 HS and Canon M5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX710 HS is significantly lighter (158g ) than the Canon M5 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on M5, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX710 HS nor Canon EOS M5 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 M5's 3.20" LCD screen is slightly larger than Canon SX710 HS's 3 screen.
In addition to the size advantage, Canon M5 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Canon SX710 HS has a fixed type screen which provides less flexibility in shooting positions compared to M5.
