Print size from Canon 5D

What is the max print size I can get from a Canon 5D sensor at 300 ppi please.... I'm not sure how to do the maths.

I believe that the 5D sensor size is 4368 pixels by 2912 pixels so just divide by 300 for the size of print in inches.

4368/300 = 14.56" and 2912/300 = 9.7"

So the size will be about 14.5 inches by 9.5 inches.

However, you do not have to choose 300 ppi if printing yourself. Many years ago I has a much lower resolution camera than now and often chose 200 ppi so that I could print near A3. This was usually OK but would look poorer if along side a 300ppi image. However fifteen years ago most people were limited to around 12 M pixels.

Thanks Dave.... That make sense.

I think it's also worth experimenting. I've printed much larger than the math would indicate possible using conventional wisdom of the 300dpi rule. It's worth remembering that you tend to view an enlarged print at the same distance as you might a smaller print and therefore the resolution needed can vary. E.g. I once printed an A0 poster from a 6mp camera (Canon 300D) and it was good enough that I had it displayed on my office wall for a couple of years. Similarly, I currently have a 120cmx100cm portrait of a cheetah on my wall that was taken on a camera that has a maximum print size of 71x48cm according to the 300dpi rule. The quality of the print is astounding even close up. Finally, remember that the media you are printing on can make a difference too. E.g. you can tend to push the print size more when using canvas or matt paper than you can if printing for a gloss finish.

I hope this helps,
