20 megapixels is a genuinely common resolution across a wide spread of camera classes — entry and mid-tier full-frame bodies, many APS-C cameras, and a fair share of high-end compacts all land close to this figure. On a standard 3:2 sensor, 20 megapixels works out to roughly 5,477 by 3,652 pixels. A genuine cross-format convergence, not a coincidence of rounding.

20.1 and 20.9 megapixels specifically show up across an unusually wide spread of cameras — Nikon's entire DX-format Z-mount lineup, several Micro Four Thirds flagships, and Sony's premium RX100 compact line all land here, making it one of the most cross-format-common resolution figures on this entire reference.
A Resolution That Rarely Feels Like a Compromise
Because 20 megapixels spans so many camera classes and price points, it's rarely a photographer's deliberate top choice the way 24 or 45 megapixels might be — it's simply where a lot of well-regarded cameras happen to land, and for the overwhelming majority of print and screen use, it performs indistinguishably from higher-resolution options at typical viewing distances.
Where the Ceiling Actually Shows Up
The limitation becomes real mainly for gallery-scale prints viewed up close, or for wildlife and sports work that relies on heavy cropping to extend effective reach — in both cases, a higher-resolution body genuinely buys real, usable headroom that 20 megapixels can't match once a significant crop has already reduced the usable pixel count. Genuinely widespread, not a niche figure.
Check the Print Size / DPI Calculator directly for the precise number at whatever print size and viewing distance you're actually planning, rather than interpolating between these three reference DPI values.

Frequently Asked Questions
Is 20 megapixels enough for a full-page magazine spread?
Generally yes — magazine printing typically runs at a lower effective DPI than a close-viewing photo print, and 20 megapixels comfortably covers a standard full-page spread at typical print production settings.
Why do so many different camera types land at close to 20 megapixels?
It represents a practical middle ground manufacturers have converged on across generations — enough resolution for the large majority of real use, without the file-size, storage and processing overhead a much higher megapixel count imposes on buffer speed and continuous shooting.
