I just started using lightroom to CROP my photos 2:3 ratio and then export jpg for clients.

I usually export:

* 1 time for sideshow, web etc. 1024*768 so that all my photos display the same size
* another time for print quality

My cropped 2:3 photos range any where from(rounded) 1400*2100 to 2600*3600. My question; should I just export these wide variety of cropped dimensions as is and let the client struggle with what sizes/quality they can print from each. OR configure my settings in LR to export all to 8*12(allowing for large or small prints), letting LR upsize/downsize (interpolation) as it see fits.

Sucessful practice suggestions?

Thx

I usually ask clients what size they require and send that size. If they change their mind about size after they get it, it's easy enough to re-send them at the new size.
