Canon R3 has a
24.0MP Full frame (36 x 24 mm ) sized Stacked CMOS sensor and features Digic X processor. On the other hand, Canon R6 has a
20.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Below you can see the R3 and R6 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R3 and Canon R6 Cameras
Canon R3 and Canon R6 have the same 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 R6 has 19% larger pixel area (43.00µm 2 vs 36.00µm 2 ) compared to Canon R3, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon R3 and Canon R6 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, R3 has scored 96, 6 points higher than R6.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon R3
or the
Canon R6 ,
including hyperfocal distance.
