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-A3 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-A3 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 339 g (0.75 lb / 11.96 oz) (including batteries).
Below you can see the front view size comparison of Canon G1 X III and Fujifilm X-A3. Fujifilm X-A3 is 11mm shorter and 11mm thinner than Canon G1 X III but it is also 2mm wider. 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-A3 doesn't. Once you put a lens on X-A3, its thickness will increase significantly.
Here is the back view size comparison of Canon G1 X III and Fujifilm X-A3.
Now lets look at the top view comparison of Canon G1 X III and Fujifilm X-A3.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A3 is significantly lighter (60g ) than the Canon G1 X III 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-A3, the total kit will weigh much higher.
With its weather sealed body, we believe that G1 X III has a big advantage over X-A3 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III and Fujifilm X-A3's LCD screens has the same diagonal size of 3".
Fujifilm X-A3 features a Tilting only screen

which is more flexible and useful especially for taking Selfie shots and video.
