How to crop to specific sizes (8x10 for example) in lightroom 3 ?

I'm trying to figure out how to do specific size crops in Lightroom v.3 but can't figure out how to get certain sizes like 5x7 or 8x10....

anyone?

in the develop module, select the crop tool, then next to the padlock there is a set of double arrows, then the words "original" click that, in that menu there is a "enter custom" enter the size that you want there,

If I lost you let me know and I'll walk you through it.

got it, easy enough... jeeze, i really don't like any of the standard print size templates... 8x10, ect... hmmmm... guess i'll be going custom and trimming the white borders a lot, lol.... where's my exacto knife?

it's a pretty powerful tool, more WYSIWYG than Photoshop, the integration between them is amazing though. I just let the local lab trim for me

Yeah, it's fun cropping for the different print sizes and having to trim as well!

I have done so much of that that I just went and bought myself a "real" paper cutter that handles up to 24" so all I need to do is some quick "slicing and dicing"!
