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 Panasonic LX10 and Fujifilm X-A7 side-by-side from the front, back and top in their relative dimensions. Panasonic LX10 has external dimensions of 106 x 60 x 42 mm (4.17 x 2.36 x 1.65″) and weighs 310 g (0.68 lb / 10.93 oz) (including batteries). Fujifilm X-A7 has external dimensions of 119 x 68 x 41 mm (4.69 x 1.5 x 1.61″) and weighs 320 g (0.71 lb / 11.29 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LX10 and the Fujifilm X-A7. Panasonic LX10 is 13mm narrower and 8mm shorter than Fujifilm X-A7 but it is also 1mm thicker. As you can tell, actually this is not a fair size comparison since Panasonic LX10 has a built-in lens but Fujifilm X-A7 doesn't. Once you put a lens on X-A7, its thickness will increase significantly.
Now lets look at the top view comparison of Panasonic LX10 and Fujifilm X-A7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic LX10 is 10g lighter than the Fujifilm X-A7 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-A7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX10 (Lumix DMC-LX15) nor Fujifilm X-A7 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-A7's 3.50" LCD screen is slightly larger than Panasonic LX10's 3 screen.
