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 R1 and Leica M10-D side-by-side from the front, back and top in their relative dimensions. Canon R1 has external dimensions of 158 x 150 x 87 mm (6.22 x 5.91 x 3.43″) and weighs 1115 g (2.46 lb / 39.33 oz) (including batteries). Leica M10-D has external dimensions of 139 x 80 x 39 mm (5.47 x 3.15x 1.54″ ) and weighs 660 g (1.46 lb / 23.28 oz) (including batteries).
Below you can see the front-view size comparison of the Canon R1 and the Leica M10-D. Leica M10-D is clearly the smaller of the two cameras. Its body is 14mm narrower, 68mm shorter and 51mm thinner than Canon R1.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica M10-D is significantly lighter (455g ) than the Canon R1 which may become a big advantage especially on long walking trips.
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 R1 and Leica M10-D have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Both the R1 and the M10-D have weather sealings in their bodies, making them resistant to water and dust.
