I've produced a set of images from my PEN E-P3 (12.3 MP) which I've upped the size a little by saving as files with 5000 pixels along the long side (4032 is native). What print size could I get to (300 dpi) and maintain very good quality? I never print so am not sure here and could never get my head around the maths,

If printing at 300 dots per inch you would need 3000 dots for every 10 inches (3000 / 300 =10)
300ppi is commercial quality. You can print at 240ppi and get perfectly good results - in fact some online printing firms use that.
At 240ppi you could get a 16" x 12" print. There are other factors of course, such as sharpeness and contrast, which contribute to how a print looks.
Thanks CB - I want to print at 16 x 12, I'll get a couple done & check the results. Ian.
Your post reminded me of this:
Which may be of some help - as it's about enlargements from Micr Four Thirds.
If you're printing at 16 x 12 and it's going on a wall (rather than in an album) and the viewing distance is greater than an album you'd be daft to print at more than 240ppi.
So what res image will you need? The arithmetic is very easy (with a calculator!) 16x240=3840, 12x240=2880 - so your image needs to be 3840 x 2880 or larger.
I think you have enough pixels already and there's no need to upscale the image. You should avoid upscaling if possible as pixels invented by software are no substitute for real pixels from the camera.
Cheers Pat - arithmetic is never easy for me - but you explanation helps!
