Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon G1 X III and Fujifilm X-T2 side-by-side from the front, back and top in their relative dimensions. Canon G1 X III has external dimensions of 115 x 78 x 51 mm (4.53 x 3.07 x 2.01″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries). Fujifilm X-T2 has external dimensions of 133 x 92 x 49 mm (5.24 x 3.62 x 1.9″) and weighs 507 g (including batteries).
Below you can see the front view size comparison of Canon G1 X III and Fujifilm X-T2. Canon G1 X III is 18mm narrower and 14mm shorter than Fujifilm X-T2 but it is also 2mm thicker. As you can tell, actually this is not a fair size comparison since Canon G1 X III has a built-in lens but Fujifilm X-T2 doesn't. Once you put a lens on X-T2, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon G1 X III is significantly lighter (108g ) than the Fujifilm X-T2 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 X-T2, the total kit will weigh much higher.
Weather Sealing
Both G1 X III and X-T2 have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Fujifilm X-T2's 3.20" LCD screen is slightly larger than Canon G1 X III's 3 screen.
