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 Olympus E-PL8 and Canon M10 side-by-side from the front, back and top in their relative dimensions. Olympus E-PL8 has external dimensions of 115 x 67 x 38 mm (4.53 x 2.64 x 1.5″) and weighs 357 g (0.79 lb / 12.59 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 Olympus E-PL8 and the Canon M10. Olympus E-PL8 has the same height with Canon M10. On the other hand, with a width of 115mm, it is 7 wider and also with a thickness of 38mm, it is 3mm thicker than Canon M10.
Here is the back view size comparison of the Olympus E-PL8 and Canon M10.
Now lets look at the top view comparison of Olympus E-PL8 and Canon M10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon M10 is significantly lighter (56g ) than the Olympus E-PL8 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Canon M10 has an APS-C sized sensor and Olympus E-PL8 has a smaller Four Thirds sensor, Olympus E-PL8's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon M10 lenses.
Weather Sealing
Unfortunately neither the Olympus PEN E-PL8 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
Olympus E-PL8 and Canon M10's LCD screens have the same diagonal size of 3.00 inches.
