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 160 and Canon Elph 115 IS side-by-side from the front, back and top in their relative dimensions. Canon 160 has external dimensions of 95 x 54 x 22 mm (3.74 x 2.13 x 0.87″) and weighs 127 g (0.28 lb / 4.48 oz) (including batteries). Canon Elph 115 IS has external dimensions of 93 x 57 x 20 mm (3.66 x 2.24 x 0.79″) and weighs 135 g (0.30 lb / 4.76 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 160 and the Canon Elph 115 IS. Canon Elph 115 IS is 2mm narrower and 2mm thinner than Canon 160 but it is also 3mm taller.
Here is the back view size comparison of the Canon 160 and Canon Elph 115 IS.
Now lets look at the top view comparison of Canon 160 and Canon Elph 115 IS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon 160 is 8g lighter than the Canon Elph 115 IS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 160 (IXUS 160) nor Canon Elph 115 IS (IXUS 132 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 Elph 115 IS's 3.00" LCD screen is slightly larger than Canon 160's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
