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 Olympus PEN-F 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). 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 Olympus E-M10 IV and the Olympus PEN-F. Olympus PEN-F is 12mm shorter and 12mm thinner than Olympus E-M10 IV but it is also 3mm wider.
Here is the back view size comparison of the Olympus E-M10 IV and Olympus PEN-F.
Now lets look at the top view comparison of Olympus E-M10 IV and Olympus PEN-F.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-M10 IV is 44g lighter than the Olympus PEN-F 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 both Olympus E-M10 IV and Olympus PEN-F have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Olympus OM-D E-M10 IV 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
Olympus E-M10 IV and Olympus PEN-F's LCD screens have the same diagonal size of 3.00 inches.
Olympus E-M10 IV features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Olympus PEN-F sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
