Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 8688 x 5792 = 50,320,896 pixels
Pixel count = 50.32 million pixels
Resolution = 50.32 mega pixels

Aspect Ratio

Width / Height: 1.5
"landscape" (horizontal) orientation
Type of aspect ratio = "Photo 3:2"

Sensor density

A full frame sensor would be 36 x 24 mm (1.5)
Pixel density would be 241 pixels/mm or 6130 pixels/inch (dpi)
Pixel pitch: 4.1 micron (very fine)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`22.07`m x `14.71`m	= 325m²
72 dpi newspaper	`3.06`m x `2.04`m	= 6.26m²
96 dpi minimum	`2.30`m x `1.53`m	= 3.52m²
150 dpi magazine	`147.1`cm x `98.1`cm	= 1.44m²
240 dpi inkjet printer	`91.9`cm x `61.3`cm	= 0.56m²
300 dpi inkjet printer	`73.6`cm x `49.0`cm	= 3607cm²
600 dpi laser printer	`36.8`cm x `24.5`cm	= 901.8cm²
1200 dpi high-end printer	`18.4`cm x `12.3`cm	= 225.5cm²

Background

For decades, advances in camera technology have been measured in 'megapixels', although more pixels doesn't always mean better quality. The same metric can also be used to describe the resolution of photos, or digital screens. This megapixel calculator brings it all together. Calculate, compare, visualise and estimate.
