Megapixel calculator

Calculate megapixels

Pixel resolution

Size = 2481 x 3507 = 8,700,867 pixels
Pixel count = 8.7MP pixels
Resolution = 8.7MP 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 69 pixels/mm or 1750 pixels/inch (dpi)
Pixel pitch: 14.5 micron (rather large)

Shape

Calculate (file) size

Print sizes (m²)

dpi	max dim (m)	max surface
10 dpi billboard	`6.30`m x `8.91`m	= 56.1m²
72 dpi newspaper	`87.5`cm x `123.7`cm	= 1.08m²
96 dpi minimum	`65.6`cm x `92.8`cm	= 0.61m²
150 dpi magazine	`42.0`cm x `59.4`cm	= 2495cm²
240 dpi inkjet printer	`26.3`cm x `37.1`cm	= 974.6cm²
300 dpi inkjet printer	`21.0`cm x `29.7`cm	= 623.7cm²
600 dpi laser printer	`10.5`cm x `14.8`cm	= 155.9cm²
1200 dpi high-end printer	`5.3`cm x `7.4`cm	= 38.98cm²

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.
