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 Ricoh WG-6 and Canon 77D side-by-side from the front, back and top in their relative dimensions. Ricoh WG-6 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 246 g (0.54 lb / 8.68 oz) (including batteries). Canon 77D has external dimensions of 131 x 100 x 76 mm (5.16 x 3.94 x 2.99″) and weighs 540 g (1.19 lb / 19.05 oz) (including batteries).
Below you can see the front view size comparison of Ricoh WG-6 and Canon 77D. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 13mm narrower, 34mm shorter and 43mm thinner than Canon 77D. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Canon 77D doesn't. Once you put a lens on 77D, its thickness will increase significantly.
Here is the back view size comparison of Ricoh WG-6 and Canon 77D.
Now lets look at the top view comparison of Ricoh WG-6 and Canon 77D.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-6 is significantly lighter (294g ) than the Canon 77D 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 77D, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh WG-6 and Canon 77D's LCD screens has the same diagonal size of 3".
On the other hand, Canon 77D sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Ricoh WG-6's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to 77D.
