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 350 HS and Canon M10 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 350 HS has external dimensions of 100 x 58 x 23 mm (3.94 x 2.28 x 0.91″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries). Canon M10 has external dimensions of 108 x 67 x 35 mm (4.25 x 2.64 x 1.38″) and weighs 301 g (0.66 lb / 10.62 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 350 HS and the Canon M10. Canon ELPH 350 HS is clearly the smaller of the two cameras. Its body is 8mm narrower, 9mm shorter and 12mm thinner than Canon M10. As you can tell, actually this is not a fair size comparison since Canon ELPH 350 HS has a built-in lens but Canon M10 doesn't. Once you put a lens on M10, its thickness will increase significantly.
Here is the back view size comparison of the Canon ELPH 350 HS and Canon M10.
Now lets look at the top view comparison of Canon ELPH 350 HS and Canon M10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 350 HS is significantly lighter (154g ) than the Canon M10 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on M10, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 350 HS (IXUS 275 HS) nor Canon EOS M10 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 and Canon M10's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon M10 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon ELPH 350 HS has a fixed type screen which provides less flexibility in shooting positions compared to M10.
