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 G900 and Panasonic GF6 side-by-side from the front, back and top in their relative dimensions. Ricoh G900 has external dimensions of 118 x 66 x 33 mm (4.65 x 2.6 x 1.3″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries). Panasonic GF6 has external dimensions of 111 x 65 x 38 mm (4.37 x 2.56 x 1.5″) and weighs 323 g (0.71 lb / 11.39 oz) (including batteries).
Below you can see the front view size comparison of Ricoh G900 and Panasonic GF6. Panasonic GF6 is 7mm narrower and 1mm shorter than Ricoh G900 but it is also 5mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh G900 has a built-in lens but Panasonic GF6 doesn't. Once you put a lens on GF6, its thickness will increase significantly.
Here is the back view size comparison of Ricoh G900 and Panasonic GF6.
Now lets look at the top view comparison of Ricoh G900 and Panasonic GF6.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Ricoh G900 is significantly lighter (76g ) than the Panasonic GF6 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 GF6, the total kit will weigh much higher.
Thanks to the weather sealed body of G900, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to GF6.
LCD Screen Size and Features
Ricoh G900 and Panasonic GF6's LCD screens has the same diagonal size of 3.00".
On the other hand, Panasonic GF6 features a Tilting screen
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Ricoh G900 has a fixed type screen which provides less flexibility in shooting positions compared to GF6.
