The sensor has a surface area of 864 mm². There are approx. 22,300,000 photosites (pixels) on this area. Pixel pitch, which is a measure of the distance between pixels, is 6.22 µm. Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.
Pixel or photosite area is 38.69 µm². The larger the photosite, the more light it can capture and the more information can be recorded.
Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. Canon 5D Mark III has a pixel density of 2.58 MP/cm².
These numbers are important in terms of assessing the overall quality of a digital camera. Generally, the bigger (and newer) the sensor, pixel pitch and photosite area, and the smaller the pixel density, the better the camera. If you want to see how 5D Mark III compares to other cameras,.

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. 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. 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 Canon EOS 5D Mark III sensor resolution.
