Digital Photo Professional: How to control output resolution

[AndyInAnnapolis]

I just started using RAW mode (actually J+R mode) on my recent vacation and am now using DPP4 to edit the RAW files to create pictures I can print & frame.  So I have a full size (not cropped) image and I save it as a jpg and my PC reports that it has a resolution of 6240x4160.  Doesn't seem to matter if I save them in DPP with a different output resolution.  Does that say than the best I can do for a raw image from my I EOS R is ~20x13" (on a 300 dpi printer)? Looking for a better understanding the best way to post process the images from my camera as well as a general rule or formula in order to determine the size I can reasonably print a photo.  TIA

How close are you going to view the image? For large formats, 150 dpi is generally OK because you view them from several feet away.

Thanks kv!  Good advice.  Since these would be at a distance I can reasonably expect to stretch a bit as long as I don’t over do it

You can also use a program - I don't know if DPP can do it - to up res a bit.

Thanks, I saw that after paging through the DPP manual but in my case I wasn't that interested in the noise reduction feature.  True it can do 2x but per kvbarkley I can stretch the image a few more inches and should still have a reasonable picture to hang on the wall
