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-T100 and Nikon D3500 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-T100 has external dimensions of 121 x 83 x 47 mm (4.76 x 3.27 x 1.85″) and weighs 448 g (0.99 lb / 15.80 oz) (including batteries). Nikon D3500 has external dimensions of 124 x 97 x 70 mm (4.88 x 3.82 x 2.76″) and weighs 365 g (0.80 lb / 12.87 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-T100 and the Nikon D3500. Fujifilm X-T100 is clearly the smaller of the two cameras. Its body is 3mm narrower, 14mm shorter and 23mm thinner than Nikon D3500.
Here is the back view size comparison of the Fujifilm X-T100 and Nikon D3500.
Now lets look at the top view comparison of Fujifilm X-T100 and Nikon D3500.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon D3500 is significantly lighter (83g ) than the Fujifilm X-T100 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-T100 and Nikon D3500 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Unfortunately neither the Fujifilm X-T100 nor Nikon D3500 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-T100 and Nikon D3500's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-T100 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 Nikon D3500 has a fixed type screen which provides less flexibility in shooting positions compared to X-T100.
