Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 30000 x 30000 = 900,000,000 pixels
Pixel count = 900 million pixels
Resolution = 900 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 833 pixels/mm or 21170 pixels/inch (dpi)
Pixel pitch: 1.2 micron (exceptionally fine)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`76.20`m x `76.20`m	= 5806m²
72 dpi newspaper	`10.58`m x `10.58`m	= 112m²
96 dpi minimum	`7.94`m x `7.94`m	= 63m²
150 dpi magazine	`5.08`m x `5.08`m	= 25.8m²
240 dpi inkjet printer	`3.17`m x `3.17`m	= 10.1m²
300 dpi inkjet printer	`2.54`m x `2.54`m	= 6.45m²
600 dpi laser printer	`127.0`cm x `127.0`cm	= 1.61m²
1200 dpi high-end printer	`63.5`cm x `63.5`cm	= 4032cm²

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.
