Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 4000 x 4000 = 16,000,000 pixels
Pixel count = 16 million pixels
Resolution = 16 mega pixels

Aspect Ratio

Width / Height: 1
"square"
Type of aspect ratio = "Square"
Type of aspect ratio = "Square" (vertical)

Sensor density

A full frame sensor would be 24 x 24 mm (1)
Pixel density would be 111 pixels/mm or 2820 pixels/inch (dpi)
Pixel pitch: 9 micron (rather large)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`10.16`m x `10.16`m	= 103m²
72 dpi newspaper	`141.1`cm x `141.1`cm	= 1.99m²
96 dpi minimum	`105.8`cm x `105.8`cm	= 1.12m²
150 dpi magazine	`67.7`cm x `67.7`cm	= 4588cm²
240 dpi inkjet printer	`42.3`cm x `42.3`cm	= 1792cm²
300 dpi inkjet printer	`33.9`cm x `33.9`cm	= 1147cm²
600 dpi laser printer	`16.9`cm x `16.9`cm	= 286.7cm²
1200 dpi high-end printer	`8.5`cm x `8.5`cm	= 71.68cm²

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.
