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 Casio EX-ZR400 and Ricoh WG-30W side-by-side from the front, back and top in their relative dimensions. Casio EX-ZR400 has external dimensions of 105 x 59 x 29 mm (4.13 x 2.32 x 1.14″) and weighs 205 g (0.45 lb / 7.23 oz) (including batteries). Ricoh WG-30W has external dimensions of 123 x 62 x 30 mm (4.84 x 2.44 x 1.18″) and weighs 194 g (0.43 lb / 6.84 oz) (including batteries).

Now lets look at the top view comparison of Casio EX-ZR400 and Ricoh WG-30W.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh WG-30W is 11g lighter than the Casio EX-ZR400 but we don't think this will make a significant difference.
