Sensor size comparison
Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.

Bigger sensors are more effective because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.

Canon EOS R1 Canon EOS 6D
Surface area:
864.00 mm² vs 855.62 mm²
Difference: 8.38 mm² (1%)
R1 sensor is slightly bigger than 6D sensor (only 1% difference).
Note: You are comparing sensors of vastly different generations. There is a gap of 12 years between Canon R1 (2024) and Canon 6D (2012). Twelve years is a huge amount of time, technology wise, resulting in newer sensor being much more efficient than the older one.
Pixel pitch
5.97 µm
6.5 µm
Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next. It tells you how close the pixels are to each other.

The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range.
Difference: 0.53 µm (9%)
Pixel pitch of 6D is approx. 9% higher than pixel pitch of R1.
Pixel area
35.64 µm²
42.25 µm²
Pixel or photosite area affects how much light per pixel can be gathered. The larger it is the more light can be collected by a single pixel.

Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions (more detail) for a given sensor size.

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor.

Higher pixel density means smaller pixels and lower pixel density means larger pixels.
Difference: 0.44 µm (19%)
Canon R1 has approx. 19% higher pixel density than Canon 6D.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:
Diagonal =  w² + h²
where w = sensor width and h = sensor height

Canon R1 diagonal

w = 36.00 mm
h = 24.00 mm
Diagonal =  36.00² + 24.00²   = 43.27 mm

Canon 6D diagonal

w = 35.80 mm
h = 23.90 mm
Diagonal =  35.80² + 23.90²   = 43.04 mm


Surface area

Surface area is calculated by multiplying the width and the height of a sensor.

R1 sensor area

Width = 36.00 mm
Height = 24.00 mm

Surface area = 36.00 × 24.00 = 864.00 mm²

6D sensor area

Width = 35.80 mm
Height = 23.90 mm

Surface area = 35.80 × 23.90 = 855.62 mm²


Pixel pitch

Pixel pitch is the distance from the center of one pixel to the center of the next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =   sensor width in mm  × 1000
sensor resolution width in pixels

R1 pixel pitch

Sensor width = 36.00 mm
Sensor resolution width = 6026 pixels
Pixel pitch =   36.00  × 1000  = 5.97 µm
6026

6D pixel pitch

Sensor width = 35.80 mm
Sensor resolution width = 5505 pixels
Pixel pitch =   35.80  × 1000  = 6.5 µm
5505


Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:
Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:
Pixel area =   sensor surface area in mm²
effective megapixels

R1 pixel area

Pixel pitch = 5.97 µm

Pixel area = 5.97² = 35.64 µm²

6D pixel area

Pixel pitch = 6.5 µm

Pixel area = 6.5² = 42.25 µm²


Pixel density

Pixel density can be calculated with the following formula:
Pixel density =  ( sensor resolution width in pixels )² / 1000000
sensor width in cm

One could also use this formula:
Pixel density =   effective megapixels × 1000000  / 10000
sensor surface area in mm²

R1 pixel density

Sensor resolution width = 6026 pixels
Sensor width = 3.6 cm

Pixel density = (6026 / 3.6)² / 1000000 = 2.8 MP/cm²

6D pixel density

Sensor resolution width = 5505 pixels
Sensor width = 3.58 cm

Pixel density = (5505 / 3.58)² / 1000000 = 2.36 MP/cm²


Sensor resolution

Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages.

1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always.

2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
(X × r) × X = effective megapixels × 1000000    →   
X =  effective megapixels × 1000000
r
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

R1 sensor resolution

Sensor width = 36.00 mm
Sensor height = 24.00 mm
Effective megapixels = 24.20
r = 36.00/24.00 = 1.5
X =  24.20 × 1000000  = 4017
1.5
Resolution horizontal: X × r = 4017 × 1.5 = 6026
Resolution vertical: X = 4017

Sensor resolution = 6026 x 4017

6D sensor resolution

Sensor width = 35.80 mm
Sensor height = 23.90 mm
Effective megapixels = 20.20
r = 35.80/23.90 = 1.5
X =  20.20 × 1000000  = 3670
1.5
Resolution horizontal: X × r = 3670 × 1.5 = 5505
Resolution vertical: X = 3670

Sensor resolution = 5505 x 3670


Crop factor

Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =   43.27 mm
sensor diagonal in mm


R1 crop factor

Sensor diagonal in mm = 43.27 mm
Crop factor =   43.27  = 1
43.27

6D crop factor

Sensor diagonal in mm = 43.04 mm
Crop factor =   43.27  = 1.01
43.04

35 mm equivalent aperture

Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture with crop factor (a.k.a. focal length multiplier).

R1 equivalent aperture

Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Canon R1, take the aperture of the lens you're using and multiply it with crop factor.

Since crop factor for Canon R1 is 1, the equivalent aperture is aperture.

6D equivalent aperture

Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Canon 6D, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon 6D is 1.01
