Whats the correct resolution in an image size 20 X30?

[Damien Symonds]

For print, do you mean?

[yk0121]

yes i want to print to 20 X 30

never printed that size before.

[Damien Symonds]

Your lab's website should tell you.  Which lab do you use?

mpixpro

I'm pretty sure they recommend 300ppi.  But check their site to make sure.

[yk0121]

On their website it says their printer outputs at 250 ppi. Is the ppi set according to the lab?

[Damien Symonds]

May I have a link to that?

Oh, that's excellent! Yes, you should use 250ppi.

YOU do it, not the lab.  Choose your Crop Tool, enter "20in" and "30in" for the size, and "250" for the resolution, then crop.  Then sharpen.

I beg you not to print such a large photo until you've taken the Sharpening Class.
