Help with background sizes

Hi there, I am designing some background tiling pattern colour variations taken from an initial background size of 1600×1200 px the tiling jpgs are then 200×1200. Obviously then they are only really good for these dimensions. Would I need to resize the jpgs for different resolutions eg. 1024×768? Or can I do these and then provide the psd which people then could resize and make their own patterns from? Hope that makes sense! Many thanks in advance.

It is best to do it all, your self so the file is easier to buyer and does not require as much modification, this will also make it more likely for the file to be accepted

Many thanks for your reply. Please could you suggest what sizes I should use?

I would in future go even higher res just so you cover all the bases, i would just check monitor resolutions on google and just do one for each size so 200×1200 200×1024 200×768 and so on

Ok thank you! I was intending to do about 80 colour styles for the one resolution. If I do all three that will be 240! Eeek! I don’t fancy doing all that if it is to be rejected!
