Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 1080 x 1440 = 1,555,200 pixels
Pixel count = 1.56 million pixels
Resolution = 1.56 mega pixels

Aspect Ratio

Width / Height: 0.75
"portrait" (vertical) orientation
Type of aspect ratio = "TV 4:3" (vertical)

Sensor density

A full frame sensor would be 18 x 24 mm (0.75)
Pixel density would be 30 pixels/mm or 760 pixels/inch (dpi)
Pixel pitch: 33.3 micron (rather large)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`2.74`m x `3.66`m	= 10m²
72 dpi newspaper	`38.1`cm x `50.8`cm	= 1935cm²
96 dpi minimum	`28.6`cm x `38.1`cm	= 1089cm²
150 dpi magazine	`18.3`cm x `24.4`cm	= 445.9cm²
240 dpi inkjet printer	`11.4`cm x `15.2`cm	= 174.2cm²
300 dpi inkjet printer	`9.1`cm x `12.2`cm	= 111.5cm²
600 dpi laser printer	`4.6`cm x `6.1`cm	= 27.87cm²
1200 dpi high-end printer	`2.3`cm x `3.0`cm	= 6.97cm²

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.
