# Megapixel calculator

A "megapixel" is one million (1.000.000) pixels. Enter the pixel dimensions of your photo, camera, screen or tv, and calculate how many megapixels that is.

### Calculate megapixels

• Size = `7680` x `4320` = `33,177,600` pixels
• Pixel count = 33.18MP pixels
• Resolution = 33.18MP pixels
• A full frame sensor would be 42.7 x 24 mm (1.78)
• Pixel density would be 213 pixels/mm or 5420 pixels/inch (dpi)
• Pixel pitch: 4.7 micron (very fine)

### Calculate (file) size

dpimax dim (imp)max surface
10 dpi billboard`64.0`ft x `36.0`ft= 2304 sq ft
72 dpi newspaper`106.7`" x `60.0`"= 44.4 sq ft
96 dpi minimum`80.0`" x `45.0`"= 25 sq ft
150 dpi magazine`51.2`" x `28.8`"= 10.2 sq ft
240 dpi inkjet printer`32.0`" x `18.0`"= 576 sq in
300 dpi inkjet printer`25.6`" x `14.4`"= 369 sq in
600 dpi laser printer`12.8`" x `7.2`"= 92.2 sq in
1200 dpi high-end printer`6.4`" x `3.6`"= 23 sq in

### 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.
