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 Ricoh WG-6 and Pentax K-70 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). Pentax K-70 has external dimensions of 126 x 93 x 74 mm (4.94 x 3.66 x 2.91″) and weighs 688 g (1.52 lb / 24.27 oz) (including batteries).
Below you can see the front-view size comparison of the Ricoh WG-6 and the Pentax K-70. Ricoh WG-6 is clearly the smaller of the two cameras. Its body is 8mm narrower, 27mm shorter and 41mm thinner than Pentax K-70. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Pentax K-70 doesn't. Once you put a lens on K-70, its thickness will increase significantly.
Here is the back view size comparison of the Ricoh WG-6 and Pentax K-70.
Now lets look at the top view comparison of Ricoh WG-6 and Pentax K-70.
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 (442g ) than the Pentax K-70 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 K-70, the total kit will weigh much higher.

LCD Screen Size and Features
Ricoh WG-6 and Pentax K-70's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Pentax K-70 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 K-70.
