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 T7i and Canon 6D MII side-by-side from the front, back and top in their relative dimensions. Canon T7i has external dimensions of 131 x 100 x 76 mm (5.16 x 3.94 x 2.99″) and weighs 532 g (1.17 lb / 18.77 oz) (including batteries). Canon 6D MII has external dimensions of 144 x 111 x 75 mm (5.67 x 4.37 x 2.95″) and weighs 765 g (1.69 lb / 26.98 oz) (including batteries).
Below you can see the front view size comparison of Canon T7i and Canon 6D MII. Canon T7i is 13mm narrower and 11mm shorter than Canon 6D MII but it is also 1mm thicker.
Here is the back view size comparison of Canon T7i and Canon 6D MII.
Now lets look at the top view comparison of Canon T7i and Canon 6D MII.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon T7i is significantly lighter (233g ) than the Canon 6D MII 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 have to also take into account the lenses that you will be using with these bodies. Since Canon 6D MII has a Full frame sensor and Canon T7i has a smaller APS-C sensor, Canon T7i's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 6D MII lenses.
Thanks to the weather sealed body of 6D MII, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to T7i.
