Width of complete Shakespeare, Casanova and 1001 Nights sets

Hello, these three are on my to-buy list, but shelf space is very, very problematic, so could someone measure the width of each of these three sets (for Casanova and 1001 Nights - with the slipcases) and let me know the exact dimensions. I'd be very grateful=)

>1 klamerin: Here you go:

Shakespeare: ~26 1/4", including the Review and a Review introductory volume and the 2 poetry volumes in their slipcase.
Casanova: 9 3/8".
1001 Nights: 9 3/4".

Thank you very much!

>3 klamerin: The Shakespeare volumes need a tall shelf (or two). The other two don’t.
