They are 3008x2000
What's the DPI? I mean in theory at 150 DPI you can get something like 20x13".
Just divide your dimension by 300 (optimal) but if you want bigger then do what I did above.
Some would say roughly 10" x 6.5" at 300ppi. You might be able to take them up to 12" x 8" with a little sharpening on them. Any higher and they could start to look a little soft... not so much a problem if they're going on a wall where you'll see them from further away.
Thom Hogan wrote some guidelines a while back:
You have 6MP images.
This is about the same pixel dimensions. I can go to ~ 8x10 at a good print dpi. It would print larger at 150 dpi. That's newspaper quality. I have about 19 MB to work with.
optimum print resolution is more than simply pixels and ppi, it has to do with the total resolution of the lens/sensor combo in line pairs per mm, which factors in the f-stop and sensor size, but only tells you a best-case scenario since it doesn't account for camera shake.
...but I doubt you're making a fine art or competition print, so print at whatever size you like. small ppi count will be masked by a longer viewing distance anyway.
tip: don't center the subject unless there's a good reason to.

i wouldnt go any bigger than a3 unless the viewer will be far awsy from it
Which leads to the question...
OP: How are you going to use the print? Framed on your wall? Taped to the inside of a window for Halloween? It really makes a difference in determining how big the print can be.
