What is the width-to-height ratio for the back covers of albums?

I know all my front covers are 1:1 (i.e. 500px x 500px), but I know that back covers are wider than they are tall.

What do you all use?

I tried cropping them to 1:1, but it ended up cutting a lot of words and stuff off the back, so that can't be right.

150 mm × 118 mm

That's for the entire backing. The folded ends are probably 8-10mm wide each, I'd guess.

Thanks.

One more question, where do you guys find album front/back covers.
I usually have good luck for front covers with Google/Amazon/Cduniverse/Walmart, and I've been using Allcdcovers for front and back recently but all their covers are scans and fairly bad quality/color, and I tried some of the back covers and none of them fit the 150x118 mm size.

I think I used to have good luck with backs at http://www.cdcovers.cc/

But for fronts, the best resource I've ever found by far is http://www.rateyourmusic.com/

i think you should hook this to get them both BACK & FRONT They are normally 400x400 or 500x500 and up
