Image resizing in Photoshop and Lightroom

[@royaltykidstv]

What should my width and height be so that I can print 4x6 images without any cropping? I noticed while trying to print with Millers Lab the shoes people are wearing are getting cut out.

Thank you so much! This is very helpful and informative.

Could you please redo this video, but make it so you talk about ALL of the different sizings that customers might want for digital imaging? Cause for example on photostock you will see 3 options and some of those options cause fringing which many people like me want to avoid, but have the highest qualities for every size
