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 R3 and Canon R6 II side-by-side from the front, back and top in their relative dimensions. Canon R3 has external dimensions of 150 x 143 x 87 mm (5.91 x 5.63 x 3.43″) and weighs 1015 g (2.24 lb / 35.80 oz) (including batteries). Canon R6 II has external dimensions of 138 x 98 x 88 mm (5.43 x 3.84 x 3.48″) and weighs 680 g (1.50 lb / 23.99 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon R6 II is significantly lighter (335g ) than the Canon R3 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 R3 and Canon R6 II have the same Canon RF lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Both the R3 and the R6 II have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Canon R3's 3.20" LCD screen is slightly larger than Canon R6 II's 3.0″ screen.
