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 Olympus E-M5 II 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). Olympus E-M5 II has external dimensions of 124 x 85 x 45 mm (4.88 x 3.35 x 1.77″) and weighs 469 g (1.03 lb / 16.54 oz) (including batteries).
Below you can see the front view size comparison of Ricoh WG-6 and Olympus E-M5 II. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 6mm narrower, 19mm shorter and 12mm thinner than Olympus E-M5 II. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Olympus E-M5 II doesn't. Once you put a lens on E-M5 Mark II, its thickness will increase significantly.
Here is the back view size comparison of Ricoh WG-6 and Olympus E-M5 II.
Now lets look at the top view comparison of Ricoh WG-6 and Olympus E-M5 II.
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 (223g ) than the Olympus E-M5 II 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 E-M5 Mark II, the total kit will weigh much higher.
LCD Screen Size and Features
Ricoh WG-6 and Olympus E-M5 II's LCD screens has the same diagonal size of 3.00".
On the other hand, Olympus E-M5 II 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 E-M5 Mark II.
