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 M3 and Fujifilm X-T200 side-by-side from the front, back and top in their relative dimensions. Canon M3 has external dimensions of 111 x 68 x 44 mm (4.37 x 2.68 x 1.73″) and weighs 366 g (0.81 lb / 12.91 oz) (including batteries). Fujifilm X-T200 has external dimensions of 121 x 84 x 55 mm (4.76 x 3.31 x 2.17″) and weighs 370 g (0.82 lb / 13.05 oz) (including batteries).
Below you can see the front-view size comparison of the Canon M3 and the Fujifilm X-T200. Canon M3 is clearly the smaller of the two cameras. Its body is 10mm narrower, 16mm shorter and 11mm thinner than Fujifilm X-T200.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon M3 is 4g lighter than the Fujifilm X-T200 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Canon M3 and Fujifilm X-T200 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Unfortunately neither the Canon EOS M3 nor Fujifilm X-T200 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Fujifilm X-T200's 3.50" LCD screen is slightly larger than Canon M3's 3" screen.
