CD Case Measurement

I don't have a ruler with me and I need to know the measurements of a CD case, and more specifically, the CD jacket inside the case. I don't have a ruler with me and I can't find the dimensions anywhere online. Can someone with a ruler handy help me?

I've measured one of my album sleeves -

Width (side to side)- 120mm exactly (pretty much).
Length (top to bottom) - 120mm also.

Awesome. Many thanks. :)

I could have sent you a J-card template, oh well xD
