Will this photo look okay at 45x30?

Taken on 6D full frame camera
Full image resolution is 5416 x 3611 @ 240ppi.
Customer wants 45x30 print but I've never printed that large before.

I think you should scrutinize it at 100% to find the answer.

Couple questions:

1. How do you figure that as 240 ppi? Seems to me that 3611/30 is around 120 ppi.

2. How do you expect anybody to be able to tell you anything about how the original will take a 2.5X blow-up from viewing a 853x1280 low res version? Can you please post a 100% crop or two?

3. Are you planning to do the upsizing yourself or to leave it to the print lab. If the former, could you please do the resizing and then post a crop from that?

It should print up nicely at nearly 3' x 4' IMHO, depending on how close people want to get to the huge print, which of course will only be reasonably viewed (ie: the whole image) from a reasonable distance anyway.

Ah, if only all the world were reasonable.

The 45 x 30" print will look as good from 45" away as the 8 x 12" print looks from 12" away.

If your client is as quality-challenged in viewing 5416 x 3611 pixel 45 x 30" print as a miserly customer taking a 960 x 1450 pixel photo from a deliberately-pixel-challenged preview DVD and printing it to 8 x 12", your client will like it just fine because it will be same (just as poor in) quality.

If your intention is to provide 240 'pixel per inch' or ppi, (which is not the same as 240 'dots per inch' or dpi!) you need to up-res via pixel interpolation 240% and provide a file which is about 13000 x 8700 pixels across.

I think it will probably look fine. If you are using an average sized monitor then it will probably be running at around 96 to 110 PPI, so just a little less resolution than you have available. So viewing it on screen at 100% should give you a good idea of what it will look like. Well at least those parts of it that will fit on the screen. Personally I have usually been quite happy with printed images that have had to be up rezzed 2 to 3 three times to hit 300 PPI, even when viewing from 12". Of course as with everything YMMV.

Make sure you leave enough space on top and bottom so you cut off the flag. You could do this by using content aware or clone...

A bud of mine prints ISO 6400 shots from a 7D at 30"x20" all the time. They look fine. This should be a piece of cake for a 6D at ISO 100. Just don't view if from a foot away.

Why would I cut off the flag? Because its blurry? Thats what happens with a long exposure with wind...
