Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 4950 x 4950 = 24,502,500 pixels
Pixel count = 24.5 million pixels
Resolution = 24.5 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 138 pixels/mm or 3490 pixels/inch (dpi)
Pixel pitch: 7.3 micron (fine)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`12.57`m x `12.57`m	= 158m²
72 dpi newspaper	`174.6`cm x `174.6`cm	= 3.05m²
96 dpi minimum	`131.0`cm x `131.0`cm	= 1.72m²
150 dpi magazine	`83.8`cm x `83.8`cm	= 0.7m²
240 dpi inkjet printer	`52.4`cm x `52.4`cm	= 2744cm²
300 dpi inkjet printer	`41.9`cm x `41.9`cm	= 1756cm²
600 dpi laser printer	`21.0`cm x `21.0`cm	= 439.1cm²
1200 dpi high-end printer	`10.5`cm x `10.5`cm	= 109.8cm²

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.
