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-E2 and Fujifilm X-Pro1 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-E2 has external dimensions of 129 x 75 x 37 mm (5.08 x 2.95 x 1.46″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries). Fujifilm X-Pro1 has external dimensions of 140 x 82 x 43 mm (5.51 x 3.23 x 1.69″) and weighs 450 g (0.99 lb / 15.87 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-E2 and the Fujifilm X-Pro1. Fujifilm X-E2 is clearly the smaller of the two cameras. Its body is 11mm narrower, 7mm shorter and 6mm thinner than Fujifilm X-Pro1.
Here is the back view size comparison of the Fujifilm X-E2 and Fujifilm X-Pro1.
Now lets look at the top view comparison of Fujifilm X-E2 and Fujifilm X-Pro1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-E2 is significantly lighter (100g ) than the Fujifilm X-Pro1 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 both Fujifilm X-E2 and Fujifilm X-Pro1 have the same Fujifilm X lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Fujifilm X-E2 nor Fujifilm X-Pro1 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-E2 and Fujifilm X-Pro1's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
