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 SX410 IS and Panasonic GX1 side-by-side from the front, back and top in their relative dimensions. Canon SX410 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). Panasonic GX1 has external dimensions of 116 x 68 x 39 mm (4.57 x 2.68 x 1.54″) and weighs 318 g (0.70 lb / 11.22 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX410 IS and the Panasonic GX1. Panasonic GX1 is 1mm shorter and 46mm thinner than Canon SX410 IS but it is also 12mm wider. As you can tell, actually this is not a fair size comparison since Canon SX410 IS has a built-in lens but Panasonic GX1 doesn't. Once you put a lens on GX1, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX410 IS and Panasonic GX1.
Now lets look at the top view comparison of Canon SX410 IS and Panasonic GX1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GX1 is 7g lighter than the Canon SX410 IS 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 GX1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX410 IS nor Panasonic Lumix DMC-GX1 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 SX410 IS and Panasonic GX1's LCD screens have the same diagonal size of 3.00 inches.
