Can I print a 24-megapixel photo at 20x30 inches?
Yes, comfortably. A 24-megapixel file on a standard 3:2 sensor produces roughly 6,000 by 4,000 pixels, which at 20x30 inches works out to exactly 200 PPI — well above the roughly 115 PPI a print viewed at a normal few-feet wall distance actually needs, and not far below the traditional close-viewing 300 DPI target.
Why 200 PPI Is Genuinely Enough Here
200 PPI comfortably clears the pixel density needed for a print viewed at arm's length or further, and even holds up reasonably well for closer inspection, just short of the traditional 300 DPI standard calibrated to examining a print from roughly a foot away. For a 20x30-inch print — large enough that most viewers naturally stand back further than that anyway — 200 PPI reads as genuinely sharp in virtually any real display context.
When 24 Megapixels Would Actually Fall Short at This Size
The one real limitation is cropping — if you've cropped significantly into the frame before printing, your effective resolution is lower than the camera's full 24-megapixel rating, and the same 20x30 print size would land at a correspondingly lower PPI. Uncropped, straight from a 24-megapixel sensor, this print size is genuinely well within range without any upscaling required.

Frequently Asked Questions
Is 200 PPI noticeably softer than a 300 PPI print?
At normal viewing distance for a print this large, most viewers won't perceive a difference — the gap between 200 and 300 PPI becomes visible mainly under close, deliberate inspection, which isn't how a 20x30-inch print is typically viewed.
What's the largest print I could make from a 24-megapixel file at a reasonable quality?
It depends entirely on your intended viewing distance — at a relaxed living-room-wall distance, a 24-megapixel file supports genuinely poster-sized output well beyond 20x30, since the required pixel density drops substantially as viewing distance increases further.
