Well Tim, if you thought you were confused before this thread, think again.

OK, officially over my head. But i get the gist, What i was really after was what size would you print if you want it to match the image properties. I think I understand that now. Thanks all

Just to confuse matters, the infamous and very popular mode 13h of the VGA video standard had non-square pixels! I have images designed for presentation on those cards and, on current hardware, they appear unnaturally broad and Botero-like.

What is the pix size? 300pix? 150pix? 72pix?. A 2540x3480 300pix image will print on 8.5"x11" just great.

You can scale up to 200% at 150pix and the image will look just great. You eyes will not noted the different between a 300pix printed and a 150pix printed.

If the image was downloaded and is 72pix, 2540 x 3480 image would be 35.278"x48.333". That's just like a 8.5" x11" 2540x2480 image with 300pix (I would guess that is the true intended size ).

What all that # mean is if you want to scale it up to 200%. You can size the image to fit and print on 13"x19" paper at 150pix and the image will look great.

I hope I didn't confused you more.

you confused me!

also one thing to remember is the final output most printers print at a max 300 dpi (or Lpi),. so having anything more the 300pdi is a waste of memory,..
the more dpi however lets you enlarge your creation without it getting pixely,..

At the animation studio, most of my art works are 11"x17" at 300dpi, and I will scale to fit and print them out at 150dpi on 24"x30" paper for presentation and they all looks great. All my personal art prints and paper models also painted in 300dpi but printed at 150dpi. Printing higher then 150dpi is total waste of ink. I 2nd what HMCS said, too.

If you input 2540dpi Width, 3480dpi Height, 300dpi Resolution, what do you get? A 8.467"x11.6" working surface.

So, a 2540x3480dpi 72dpi Res image scale to fit on a 8.5"x11" paper, the image quality will be identical to a 2540x3480dpi 300dpi Res image print on 8.5"x11" paper.

Well I'll give it a try:
There are three numbers:
-pixels of the digital image in each direction (for example 100x200px)
-the size of the real world-picture (for example 10x20 inch)
-the resolution of the digital image (for example 10dpi)
The resolution connects the two "worlds" as it tells you into how many pixels a real-world distance is devided. In the example, 10dpi means you have 10 rows of pixels in 1 inch. So taking this resolution, a picture of 10x20 inch will result in a digital image of (10*10)x(20x10)px=100x200px. On the other way, printed with the same resolution, a digital image of 480x640px would result in a real-life picture of 48x64 inch.
The numbers were chosen for nice calculations, more common are resolutions of 72dpi, up to 400dpi. Without knowing the resolution of your picture, you are not able to print it to scale. But with the numbers given by the posts above, you can determine the size in which the picture will look good, which means that the print is yet so small that you don't see the individual pixels.
