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 Fujifilm X-A3 and Olympus PEN-F side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A3 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 339 g (0.75 lb / 11.96 oz) (including batteries). Olympus PEN-F has external dimensions of 125 x 72 x 37 mm (4.92 x 2.83 x 1.46″) and weighs 427 g (0.94 lb / 15.06 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-A3 and the Olympus PEN-F. Fujifilm X-A3 is 8mm narrower and 5mm shorter than Olympus PEN-F but it is also 3mm thicker.
Here is the back view size comparison of the Fujifilm X-A3 and Olympus PEN-F.
Now lets look at the top view comparison of Fujifilm X-A3 and Olympus PEN-F.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-A3 is significantly lighter (88g ) than the Olympus PEN-F 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 Fujifilm X-A3 has an APS-C sized sensor and Olympus PEN-F has a smaller Four Thirds sensor, Olympus PEN-F's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-A3 lenses.
Weather Sealing
Unfortunately neither the Fujifilm X-A3 nor Olympus PEN-F 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
Fujifilm X-A3 and Olympus PEN-F's LCD screens have the same diagonal size of 3.00 inches.
Fujifilm X-A3 features a

Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
