Would an image 1800 x1200 pixels be enough for an A2 print?

I work it out at 24in x 16in @ 75 pls per in but do they print at 75 pls per in? :shrug:

I'm only asking as I think it's on it's limit!
 
You ideally need at least 150dpi for decent viewing distance....75 would be a bit too low show any detail

If you are printing the image yourself then you could possible print that size, but it won't be very good quality, you would get a good A4 print, but not A2, but dpi need to be at least 150 dpi.

If sending to a print house then you are nowhere near the mark, most sites have a quality scale to give you an indication of how good you image would be at different sizes.

Most photolabs print at 300 dpi for anything upto A4 and around 257 dpi for A3 or bigger print. To get a A2 image from photobox as an example, you would need a 3000 x 2000 pixel image to get a decent quality print at A2.

Not true. It depends on the size. You don't need 150dpi, or even 75dpi, for a billboard poster.

It's a good idea to keep 3000 x 2000 in mind as the size needed to get a decent quality print of any size.

You could do an A2 print from a 3000x2000 image at about 128 ppi, and if you were standing far enough away to appreciate the picture then it would look fine.

You could also do an A1 print from a 3000x2000 image at about 91 ppi. It wouldn't look as good as the A2 print close up, of course, but since it's bigger you'd want to look at it from further away - and the increased viewing difference exactly cancels out the decreased resolution. So it would look fine.
 
I have a print on my living room wall, image was at 75dpi, printer prints at 1440 dpi, its about 17" x 55" and looks great.

It really depends on what the print is, heres mine, its a single shot and cropped!

I've re-wrapped it now as that was my first attempt, the white edges are now wrapped tidy :)

Yes. That's the whole point. The bigger the picture, the bigger the viewing distance, the lower the resolution you can get away with.

I know...that's what I said wasn't it??

When I mean't 75dpi is probably a bit low for an A2 print, I'm guessing the use would be for a photo, which people may want to look at closely to see detail!
 
It really depends on what admirable wants to use the image for as you suggested.

I have managed to get very good A2 prints (ok, in my opinion, I'm please with the results) with images around the 3000 x 2000 pixel size printing them at 257 dpi from photobox and you don't have to stand miles away to appreciate the image.

There are software add on's for photoshop that increase the size of your image (The software interprets the image and basically add extra pixels into the original image, if my understanding of their process is correct) so you can say, print a A3 image from a A4 image, not sure how good they are or which ones to recommend, have not used this type of software.
