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 G12 and Canon SX220 HS side-by-side from the front, back and top in their relative dimensions. Canon G12 has external dimensions of 112 x 76 x 48 mm (4.41 x 2.99 x 1.89″) and weighs 401 g (0.88 lb / 14.14 oz) (including batteries). Canon SX220 HS has external dimensions of 106 x 59 x 33 mm (4.17 x 2.32 x 1.3″) and weighs (including batteries).
Below you can see the front-view size comparison of the Canon G12 and the Canon SX220 HS. Canon SX220 HS is clearly the smaller of the two cameras. Its body is 6mm narrower, 17mm shorter and 15mm thinner than Canon G12.
Here is the back view size comparison of the Canon G12 and Canon SX220 HS.
Now lets look at the top view comparison of Canon G12 and Canon SX220 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX220 HS is 401g lighter than the Canon G12 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot G12 nor Canon SX220 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 SX220 HS's 3.00" LCD screen is slightly larger than Canon G12's 2.8 screen.
On the other hand, Canon G12 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Canon SX220 HS has a fixed type screen which provides almost no flexibility in shooting positions compared to G12.
