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 S120 and Canon SX230 HS side-by-side from the front, back and top in their relative dimensions. Canon S120 has external dimensions of 100 x 59 x 29 mm (3.94 x 2.32 x 1.14″) and weighs 217 g (0.48 lb / 7.65 oz) (including batteries). Canon SX230 HS has external dimensions of 106 x 62 x 33 mm (4.17 x 2.44 x 1.3″) and weighs 223 g (0.49 lb / 7.87 oz) (including batteries).
Below you can see the front-view size comparison of the Canon S120 and the Canon SX230 HS. Canon S120 is clearly the smaller of the two cameras. Its body is 6mm narrower, 3mm shorter and 4mm thinner than Canon SX230 HS.
Here is the back view size comparison of the Canon S120 and Canon SX230 HS.
Now lets look at the top view comparison of Canon S120 and Canon SX230 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon S120 is 6g lighter than the Canon SX230 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot S120 nor Canon PowerShot SX230 HS 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 S120 and Canon SX230 HS's LCD screens have the same diagonal size of 3.00 inches.
