tl;dr:

    Viewing distance PPI
    1 meter          170 pixels/inch
which is to say that a 12mp image is going to max out at 18x24"

…supposing the pixels are the limiting factor, and that you’re interested in viewing an 18x24” image from 3 feet away.

If the optics that captured the image are such that its sharpest feature spans multiple pixels, TFA provides some handy rules of thumb to adjust your print size down accordingly.

Half-in-jest, I think we should put some pressure on the International Bureau of Weights and Measures to standardize dots per meter (DPM), and then have the EU follow through with a new law or two to accelerate adoption.

Yes, the meter/inch thing is jarring.

Angular measure only has degrees. We should be fine with angles subjected to a point, unless somebody decided fractions beat decimals.
