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 G9 X and Samsung NX300M side-by-side from the front, back and top in their relative dimensions. Canon G9 X has external dimensions of 98 x 58 x 31 mm (3.86 x 2.28 x 1.21″) and weighs 209 g (0.46 lb / 7.37 oz) (including batteries). Samsung NX300M has external dimensions of 122 x 64 x 41 mm (4.8 x 2.52 x 1.61″) and weighs 331 g (0.73 lb / 11.68 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G9 X and the Samsung NX300M. Canon G9 X is clearly the smaller of the two cameras. Its body is 24mm narrower, 6mm shorter and 10mm thinner than Samsung NX300M. As you can tell, actually this is not a fair size comparison since Canon G9 X has a built-in lens but Samsung NX300M doesn't. Once you put a lens on NX300M, its thickness will increase significantly.
Now lets look at the top view comparison of Canon G9 X and Samsung NX300M.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G9 X is significantly lighter (122g ) than the Samsung NX300M 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 NX300M, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot G9 X nor Samsung NX300M 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
Samsung NX300M's 3.30" LCD screen is slightly larger than Canon G9 X's 3 screen.
In addition to the size advantage, Samsung NX300M 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 G9 X has a fixed type screen which provides less flexibility in shooting positions compared to NX300M.
