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 170 IS and Canon ELPH 130 side-by-side from the front, back and top in their relative dimensions. Canon 170 IS has external dimensions of 100 x 58 x 23 mm (3.94 x 2.28 x 0.91″) and weighs 141 g (0.31 lb / 4.97 oz) (including batteries). Canon ELPH 130 has external dimensions of 95 x 56 x 21 mm (3.74 x 2.2 x 0.83″) and weighs 133 g (0.29 lb / 4.69 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 170 IS and the Canon ELPH 130. Canon ELPH 130 is clearly the smaller of the two cameras. Its body is 5mm narrower, 2mm shorter and 2mm thinner than Canon 170 IS.
Here is the back view size comparison of the Canon 170 IS and Canon ELPH 130.
Now lets look at the top view comparison of Canon 170 IS and Canon ELPH 130.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 130 is 8g lighter than the Canon 170 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 170 IS (IXUS 170) nor Canon ELPH 130 (IXUS 140) 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 ELPH 130's 3.00" LCD screen is slightly larger than Canon 170 IS's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
