Just cropping down by a DX factor (1.5) you lose more than 1/2 the pixels, 3936 X 2624 = 10.3MP (see table for large). 10.3 MP still makes a decent print up to 12 X 8" or 10 X 8".
That chart is incorrect.

Go to Image, then drop down to Image Size.
It will tell you what size you can print at 300
as you zoom in. Try it, it is easy to use.

True dat. It's easy and fast. When I
use it, I keep in mind that it's really
just an approximation at best. If I
took it at face value, I'd wonder how
I do the impossible time after time !
What it's especially handy at is for
relative judgments. IOW, if you have
a perfectly fine 24" print, and then
you need to make a 36", it gives you
the ratio, even tho it also had "lied"
about what size had been possible in
the first place.
To be fair, let's just say that Adobe's
size estimations can be conservative,
reeeeeeeally conservative.

You can go way bigger than 8x12. Don’t go by the charts. They are not real world.

Adobe doesn't lie about image size. It only reports what the value is in the metadata tag. It is being absolutely truthful. Exiftool, DXO, Capture One, etc would all be lying if you were correct.

You can crop an image to where YOU are comfortable with the results. There is a BIG difference in the requirements for something posted on the web and printed 30 x 40. Best of luck.
For a 30x40 image, you only need around 50 ppi. I have printed 40x60 at 50 ppi from a Nikon D70S, which was only 6.1 mp, and gotten no complaints about image softness or lack of clarity.
Required resolution, in pixels, is not about print size as much as it is about viewing distance. If the human eye could discern 300ppi detail at 10 ft, then it would make sense to have as many pixels as possible. But it can't, so printing larger images at high resolutions is completely unnecessary.
The explanation is here:

Thanks. I purposely skipped talking about normal viewing distance to avoid starting a war of words. I remember the huge images in Grand Central Station sponsored by Kodak. I am from NYC.
