How to prepare the file

Crop your image to the 12 × 12 shape so the lab does not cut anything off.
Compare your pixels with 3,600 × 3,600. The calculator above does it for you.
Upscale with the smallest scale that reaches the size, then resize to the exact pixels.
Export PNG, or JPG at quality 95, and order the print at this size.

Questions

How many pixels do I need for a 12 × 12 in print at 300 DPI?

3,600 × 3,600 pixels: 12 × 12 inches multiplied by 300 dots per inch, rounded to whole pixels.

Is 300 DPI good enough for 12 × 12 in?

300 DPI is the photo lab standard for prints you hold in your hand or view at arm's length.

Can a phone photo be printed at 12 × 12 in?

Yes, with 2× upscaling. A 12 MP photo of 4032 × 3024 falls short of 3,600 × 3,600 on its own.

What does DPI mean for a digital file?

Dots per inch is how many image pixels land on each inch of paper. The pixel count is what matters: the DPI field saved in a file does not change the image, the printer scales the pixels to the paper size.

Does upscaling add real detail for printing?

It adds plausible detail: sharper edges and texture instead of the soft blur of ordinary resizing. It cannot recover detail the camera never captured, such as text too small to read.
