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 Canon G9 X and Pentax WG-3 GPS side-by-side from the front, back and top in their relative dimensions. Canon G9 X has external dimensions of 98 x 58 x 31 mm (3.86 x 2.28 x 1.21″) and weighs 209 g (0.46 lb / 7.37 oz) (including batteries). Pentax WG-3 GPS has external dimensions of 125 x 64 x 33 mm (4.9 x 2.5 x 1.3″) and weighs 238 g (0.52 lb / 8.40 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G9 X is 29g lighter than the Pentax WG-3 GPS but we don't think this will make a significant difference.
