Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 5120 x 4096 = 20,971,520 pixels
Pixel count = 20.97 million pixels
Resolution = 20.97 mega pixels

Aspect Ratio

Width / Height: 1.25
"landscape" (horizontal) orientation

Sensor density

A full frame sensor would be 30 x 24 mm (1.25)
Pixel density would be 142 pixels/mm or 3610 pixels/inch (dpi)
Pixel pitch: 7 micron (fine)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`13.01`m x `10.40`m	= 135m²
72 dpi newspaper	`180.6`cm x `144.5`cm	= 2.61m²
96 dpi minimum	`135.5`cm x `108.4`cm	= 1.47m²
150 dpi magazine	`86.7`cm x `69.4`cm	= 0.6m²
240 dpi inkjet printer	`54.2`cm x `43.3`cm	= 2349cm²
300 dpi inkjet printer	`43.3`cm x `34.7`cm	= 1503cm²
600 dpi laser printer	`21.7`cm x `17.3`cm	= 375.8cm²
1200 dpi high-end printer	`10.8`cm x `8.7`cm	= 93.96cm²

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.
