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 Leica Q-P and Leica M Typ 240 side-by-side from the front, back and top in their relative dimensions. Leica Q-P has external dimensions of 130 x 80 x 93 mm (5.12 x 3.15 x 3.66″) and weighs 640 g (1.41 lb / 22.58 oz) (including batteries). Leica M Typ 240 has external dimensions of 139 x 80 x 42 mm (5.47 x 3.15 x 1.65″) and weighs 680 g (1.50 lb / 23.99 oz) (including batteries).
Below you can see the front-view size comparison of the Leica Q-P and the Leica M Typ 240. As you can tell, actually this is not a fair size comparison since Leica Q-P has a built-in lens but Leica M Typ 240 doesn't. Once you put a lens on M Typ 240, its thickness will increase significantly.
Here is the back view size comparison of the Leica Q-P and Leica M Typ 240.
Now lets look at the top view comparison of Leica Q-P and Leica M Typ 240.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Leica Q-P is 40g lighter than the Leica M Typ 240 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 M Typ 240, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the M Typ 240, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the Q-P.
LCD Screen Size and Features
Leica Q-P and Leica M Typ 240'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.
