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-M10 IV and Fujifilm X-A2 side-by-side from the front, back and top in their relative dimensions. 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). Fujifilm X-A2 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M10 IV and the Fujifilm X-A2. Fujifilm X-A2 is clearly the smaller of the two cameras. Its body is 5mm narrower, 17mm shorter and 9mm thinner than Olympus E-M10 IV.
Here is the back view size comparison of the Olympus E-M10 IV and Fujifilm X-A2.
Now lets look at the top view comparison of Olympus E-M10 IV and Fujifilm X-A2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A2 is 33g lighter than the Olympus E-M10 IV but we don't think this will make a significant difference.
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 Fujifilm X-A2 has an APS-C sized sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-A2 lenses.
Weather Sealing
Unfortunately neither the Olympus OM-D E-M10 IV nor Fujifilm X-A2 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus E-M10 IV and Fujifilm X-A2's LCD screens have the same diagonal size of 3.00 inches.
