Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 4032 x 3024 = 12,192,768 pixels
Pixel count = 12.19 million pixels
Resolution = 12.19 mega pixels

Aspect Ratio

Width / Height: 1.33
"landscape" (horizontal) orientation
Type of aspect ratio = "TV 4:3"

Sensor density

A full frame sensor would be 31.9 x 24 mm (1.33)
Pixel density would be 112 pixels/mm or 2840 pixels/inch (dpi)
Pixel pitch: 8.9 micron (rather large)

Shape

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`10.24`m x `7.68`m	= 78.7m²
72 dpi newspaper	`142.2`cm x `106.7`cm	= 1.52m²
96 dpi minimum	`106.7`cm x `80.0`cm	= 0.85m²
150 dpi magazine	`68.3`cm x `51.2`cm	= 3496cm²
240 dpi inkjet printer	`42.7`cm x `32.0`cm	= 1366cm²
300 dpi inkjet printer	`34.1`cm x `25.6`cm	= 874cm²
600 dpi laser printer	`17.1`cm x `12.8`cm	= 218.5cm²
1200 dpi high-end printer	`8.5`cm x `6.4`cm	= 54.63cm²

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.
