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 Sony RX100 and Canon M50 side-by-side from the front, back and top in their relative dimensions. Sony RX100 has external dimensions of 102 x 58 x 36 mm (4 x 2.29 x 1.41″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries). Canon M50 has external dimensions of 116 x 88 x 59 mm (4.57 x 3.46 x 2.32″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries).
Below you can see the front-view size comparison of the Sony RX100 and the Canon M50. Sony RX100 is clearly the smaller of the two cameras. Its body is 14mm narrower, 30mm shorter and 23mm thinner than Canon M50. As you can tell, actually this is not a fair size comparison since Sony RX100 has a built-in lens but Canon M50 doesn't. Once you put a lens on M50, its thickness will increase significantly.
Here is the back view size comparison of the Sony RX100 and Canon M50.
Now lets look at the top view comparison of Sony RX100 and Canon M50.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony RX100 is significantly lighter (150g ) than the Canon M50 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 M50, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-RX100 nor Canon EOS M50 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
Sony RX100 and Canon M50's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon M50 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. Sony RX100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to M50.
