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 Canon SX420 IS and Fujifilm X-A1 side-by-side from the front, back and top in their relative dimensions. Canon SX420 IS has external dimensions of 104 x 69 x 85 mm (4.09 x 2.72 x 3.35″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries). Fujifilm X-A1 has external dimensions of 117 x 67 x 39 mm (4.6 x 2.62 x 1.54″) and weighs 330 g (0.73 lb / 11.64 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX420 IS and the Fujifilm X-A1. Fujifilm X-A1 is 2mm shorter and 46mm thinner than Canon SX420 IS but it is also 13mm wider. As you can tell, actually this is not a fair size comparison since Canon SX420 IS has a built-in lens but Fujifilm X-A1 doesn't. Once you put a lens on X-A1, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX420 IS and Fujifilm X-A1.
Now lets look at the top view comparison of Canon SX420 IS and Fujifilm X-A1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX420 IS is 5g lighter than the Fujifilm X-A1 but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on X-A1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX420 IS nor Fujifilm X-A1 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
Canon SX420 IS and Fujifilm X-A1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Fujifilm X-A1 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 Canon SX420 IS has a fixed type screen which provides less flexibility in shooting positions compared to X-A1.
