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 G16 and Casio EX-ZS10 side-by-side from the front, back and top in their relative dimensions. Canon G16 has external dimensions of 109 x 76 x 40 mm (4.29 x 2.99 x 1.57″) and weighs 356 g (0.78 lb / 12.56 oz) (including batteries). Casio EX-ZS10 has external dimensions of 103 x 59 x 20 mm (4.06 x 2.32 x 0.79″) and weighs (including batteries).
Below you can see the front-view size comparison of the Canon G16 and the Casio EX-ZS10. Casio EX-ZS10 is clearly the smaller of the two cameras. Its body is 6mm narrower, 17mm shorter and 20mm thinner than Canon G16.
Here is the back view size comparison of the Canon G16 and Casio EX-ZS10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-ZS10 is 356g lighter than the Canon G16 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G16 nor Casio Exilim EX-ZS10 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G16's 3.00" LCD screen is slightly larger than Casio EX-ZS10's screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
