Look at the Resolution in a program like Photoshop or Lightroom. Resolution is the number of pixels. If the photo ratio is 4x3, 48MP would be 8,000 x 6,000 pixels
8,000 x 6,000 = 48,000,000 = 48 megapixels (MP)
A high resolution print has a minimum of 360 pixels per inch (ppi)
8,000 pixels / 360 pixels per inch = 22 inches
6,000 pixels / 360 pixels per inch = 16 inches
You can easily print 22" x 16" at photographic quality.
Since a very large print should be viewed from a farther distance, the minimum is 150 pixels per inch.
Do the math and you 'll see you can print 53" x 40" at 150 pixels per inch.
These are standards set by print companies like MPIX and Canvas on Demand. Online print companies normally post there requirements on their web site.
I have an Epson Sure Color P800 Printer. I can print 17"x25" at photographic quality. That printer recommends 360 ppi (pixels for inch) minimum. The prints are as good or better than what I can purchase from print companies. There's a lot to learn about printing at that quality, like ICC Profiles for the paper being used. ICC Profiles can be downloaded from paper suppliers like Red River. Each paper has it's own profile.
I create my own custom ICC Profiles with a device from XRite called a ColorMunki.
300 pixels per inch is considered "high resolution". It all depends on the final output obviously but the physical size @ 300 ppi is the safest limit for reproduction. There is some leeway depending on subject matter. We even print 150 dpi if it's small enough.But that is fairly rare.Look at the Resolution in a program like Photoshop or Lightroom.
