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 SX410 IS and Olympus E-M10 IV side-by-side from the front, back and top in their relative dimensions. Canon SX410 IS has external dimensions of 104 x 69 x 85 mm (4.09 x 2.72 x 3.35″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries). Olympus E-M10 IV has external dimensions of 122 x 84 x 49 mm (4.8 x 3.31 x 1.93″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX410 IS and the Olympus E-M10 IV. Canon SX410 IS is 18mm narrower and 15mm shorter than Olympus E-M10 IV but it is also 36mm thicker. As you can tell, actually this is not a fair size comparison since Canon SX410 IS has a built-in lens but Olympus E-M10 IV doesn't. Once you put a lens on E-M10 IV, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX410 IS and Olympus E-M10 IV.
Now lets look at the top view comparison of Canon SX410 IS and Olympus E-M10 IV.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX410 IS is significantly lighter (58g ) than the Olympus E-M10 IV 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 E-M10 IV, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX410 IS nor Olympus OM-D E-M10 IV 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 SX410 IS and Olympus E-M10 IV's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M10 IV 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 SX410 IS has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
