Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon G1 X III and Canon 7D 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 7D has external dimensions of 148 x 111 x 74 mm (5.83 x 4.37 x 2.91″) and weighs 860 g (1.90 lb / 30.34 oz) (including batteries).
Below you can see the front view size comparison of Canon G1 X III and Canon 7D. Canon G1 X III is clearly the smaller of the two cameras. Its body is 33mm narrower, 33mm shorter and 23mm thinner than Canon 7D. As you can tell, actually this is not a fair size comparison since Canon G1 X III has a built-in lens but Canon 7D doesn't. Once you put a lens on 7D, its thickness will increase significantly.

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 (461g ) than the Canon 7D 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 7D, the total kit will weigh much higher.
Weather Sealing
Both G1 X III and 7D have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Canon G1 X III and Canon 7D's LCD screens has the same diagonal size of 3.
On the other hand, Canon G1 X III sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Canon 7D's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G1 X III.
Canon G1 X III has a 24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Canon 7D has a 18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Dual Digic 4 processor.
Canon G1 X III's sensor provides 6MP more than Canon 7D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the G1 X III and 7D sensor size comparison.

Sensor Size and Resolution Comparison image of Canon G1 X III and Canon 7D Cameras
Canon G1 X III and Canon 7D have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 7D has 33% larger pixel area (18.54µm2 vs 13.84µm2) compared to Canon G1 X III, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
In this section, we rank and compare Canon G1 X III and Canon 7D for five different photography types in order to make your decision process easier in case you are specifically interested in one or more of these areas.
