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 Sony TX100V 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). Sony TX100V has external dimensions of 97 x 59 x 18 mm (3.82 x 2.32 x 0.71″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 160 and the Sony TX100V. Canon 160 is 2mm narrower and 5mm shorter than Sony TX100V but it is also 4mm thicker.
Here is the back view size comparison of the Canon 160 and Sony TX100V.
Now lets look at the top view comparison of Canon 160 and Sony TX100V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon 160 is 20g lighter than the Sony TX100V but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 160 (IXUS 160) nor Sony Cyber-shot DSC-TX100V 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
Sony TX100V's 3.50" 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.
