Pixel size to print a certain size
I've been trying to hunt to the answer for this, and I see similar questions but nothing that quite gets me what I need.

I want to create a template whereby I can make a series of images that I can save as jpgs, upload to my blog, and people can print them. When they print, I want them to be one quarter of a sheet of paper (fit four to a page).

I tried creating a new image using the "inches" specification and those inches seem to have no bearing on inches in real life once printed.

So then I figured that a sheet of paper is 8.5 by 11 and I want a resolution of 300 dpi.

So 8.5 times 300: 2,550 pixels. Times that by 0.25 to get a quarter of it: 637.5 (which gets rounded to 638 pixels).

11 times 300: 3,300 pixels. Times that by 0.25= 825 pixels.

So I put in for 638 pixels by 825 pixels and 300 dpi.

I created my image. I saved it as a jpg at full resolution. I uploaded it to my site and tested out the printing.

It took up most of a sheet of paper. Not even close to being a quarter of a sheet. I cannot figure out what I'm doing wrong!

RE: Pixel size to print a certain size
That is very helpful! Thank you so much.

I guess I will try putting all four images together into one "sheet" and instruct people to click "fit to one page" when printing and that way they should get close to the right size.
