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 G1 X III and Canon T6i side-by-side from the front, back and top in their relative dimensions. Canon G1 X III has external dimensions of 115 x 78 x 51 mm (4.53 x 3.07 x 2.01″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries). Canon T6i has external dimensions of 132 x 101 x 78 mm (5.2 x 3.98 x 3.07″) and weighs 555 g (1.22 lb / 19.58 oz) (including batteries).
Below you can see the front-view size comparison of the Canon G1 X III and the Canon T6i. Canon G1 X III is clearly the smaller of the two cameras. Its body is 17mm narrower, 23mm shorter and 27mm thinner than Canon T6i. As you can tell, actually this is not a fair size comparison since Canon G1 X III has a built-in lens but Canon T6i doesn't. Once you put a lens on T6i, its thickness will increase significantly.
Here is the back view size comparison of the Canon G1 X III and Canon T6i.
Now lets look at the top view comparison of Canon G1 X III and Canon T6i.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G1 X III is significantly lighter (156g ) than the Canon T6i which may become a big advantage especially on long walking trips.
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 T6i, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the G1 X III has a big advantage over the T6i which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III and Canon T6i's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
