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 ELPH 190 IS and Canon ELPH 350 HS side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 190 IS is 9g lighter than the Canon ELPH 350 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 190 IS nor Canon PowerShot ELPH 350 HS (IXUS 275 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 350 HS's 3.00" LCD screen is slightly larger than Canon ELPH 190 IS's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
