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 Nikon S4100 and Ricoh WG-20 side-by-side from the front, back and top in their relative dimensions. Nikon S4100 has external dimensions of 95 x 57 x 20 mm (3.74 x 2.24 x 0.79″) and weighs (including batteries). Ricoh WG-20 has external dimensions of 114 x 58 x 28 mm (4.49 x 2.28 x 1.1″) and weighs 164 g (0.36 lb / 5.78 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S4100 and the Ricoh WG-20. Nikon S4100 is clearly the smaller of the two cameras. Its body is 19mm narrower, 1mm shorter and 8mm thinner than Ricoh WG-20.

Now lets look at the top view comparison of Nikon S4100 and Ricoh WG-20.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S4100 is 164g lighter than the Ricoh WG-20 but we don't think this will make a significant difference.

Thanks to the weather-sealed body of the WG-20, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the S4100.
LCD Screen Size and Features
Nikon S4100's 3.00" LCD screen is slightly larger than Ricoh WG-20's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
