Body comparison: Canon T3i vs 77D
The physical size and weight of the Canon T3i and the Canon 77D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the T3i – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 77D is somewhat smaller (2 percent) than the Canon T3i. Moreover, the 77D is markedly lighter (5 percent) than the T3i. In this context, it is worth noting that neither the T3i nor the 77D are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The T3i was launched at a markedly lower price (by 33 percent) than the 77D, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.
Sensor comparison: Canon T3i vs 77D
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the 77D uses a more advanced image processing engine (DIGIC 7) than the T3i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the 77D offers a higher resolution of 24 megapixels, compared with 17.9 MP of the T3i. This megapixels advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the 77D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the T3i). However, it should be noted that the 77D is much more recent (by 6 years) than the T3i, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS Rebel T3i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Canon EOS 77D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200..
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the 77D offers substantially better image quality than the T3i (overall score 13 points higher). The advantage is based on 1.5 bits higher color depth, 1.8 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 77D provides a faster frame rate than the T3i. It can shoot movie footage at 1080/60p, while the T3i is limited to 1080/30p.
Feature comparison: Canon T3i vs 77D
Beyond body and sensor, cameras can and do differ across a range of features. The T3i and the 77D are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 77D has a touchscreen, while the T3i has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
Concerning the storage of imaging data, both the T3i and the 77D write their files to SDXC cards.
Connectivity comparison: Canon T3i vs 77D
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS Rebel T3i and Canon EOS 77D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the T3i does not offer wifi capability.
The 77D is a recent model that features in the current product line-up of Canon. In contrast, the T3i has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the T3i was succeeded by the Canon T4i.
Review summary: Canon T3i vs 77D
So what conclusions can be drawn? Is the Canon T3i better than the Canon 77D or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS Rebel T3i:
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2011).
Advantages of the Canon EOS 77D:
- More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
- Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).

If the count of relative strengths (bullet points above) is taken as a measure, the 77D is the clear winner of the contest (15 : 2 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the T3i or the 77D. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
