Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 1500 x 2100 = 3,150,000 pixels
Pixel count = 3.15MP pixels
Resolution = 3.15MP pixels

Aspect Ratio

Width / Height: 0.71
"portrait" (vertical) orientation

Sensor density

A full frame sensor would be 17 x 24 mm (0.71)
Pixel density would be 42 pixels/mm or 1060 pixels/inch (dpi)
Pixel pitch: 24 micron (rather large)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`3.81`m x `5.33`m	= 20.3m²
72 dpi newspaper	`52.9`cm x `74.1`cm	= 3920cm²
96 dpi minimum	`39.7`cm x `55.6`cm	= 2205cm²
150 dpi magazine	`25.4`cm x `35.6`cm	= 903.2cm²
240 dpi inkjet printer	`15.9`cm x `22.2`cm	= 352.8cm²
300 dpi inkjet printer	`12.7`cm x `17.8`cm	= 225.8cm²
600 dpi laser printer	`6.3`cm x `8.9`cm	= 56.45cm²
1200 dpi high-end printer	`3.2`cm x `4.4`cm	= 14.11cm²

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.
