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 Panasonic GM1 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). Panasonic GM1 has external dimensions of 99 x 55 x 30 mm (3.88 x 2.16 x 1.2″) and weighs 204 g (0.45 lb / 7.20 oz) (including batteries).
Below you can see the front view size comparison of Ricoh WG-6 and Panasonic GM1. Panasonic GM1 is clearly the smaller of the two cameras. Its body is 19mm narrower, 11mm shorter and 3mm thinner than Ricoh WG-6. As you can tell, actually this is not a fair size comparison since Ricoh WG-6 has a built-in lens but Panasonic GM1 doesn't. Once you put a lens on GM1, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic GM1 is significantly lighter (42g ) than the Ricoh WG-6 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 GM1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather sealed body of WG-6, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to GM1.
LCD Screen Size and Features
Ricoh WG-6 and Panasonic GM1's LCD screens has the same diagonal size of 3.00".
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
