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 Nikon D7500 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). Nikon D7500 has external dimensions of 136 x 104 x 73 mm (5.35 x 4.09 x 2.87″) and weighs 720 g (1.59 lb / 25.40 oz) (including batteries).
Below you can see the front view size comparison of Ricoh WG-6 and Nikon D7500. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 18mm narrower, 38mm shorter and 40mm thinner than Nikon D7500. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Nikon D7500 doesn't. Once you put a lens on D7500, its thickness will increase significantly.
Here is the back view size comparison of Ricoh WG-6 and Nikon D7500.
Now lets look at the top view comparison of Ricoh WG-6 and Nikon D7500.
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 (474g ) than the Nikon D7500 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 D7500, the total kit will weigh much higher.
LCD Screen Size and Features
Nikon D7500's 3.2 LCD screen is slightly larger than Ricoh WG-6's 3" screen.
In addition to the size advantage, Nikon D7500 LCD screen also has a Tilting feature
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Ricoh WG-6 has a fixed type screen which provides less flexibility in shooting positions compared to D7500.
