How big do the autograph papers need to be?

Sorry if I posted in the wrong area since I'm new here, but my question is the in title. I'm going to WDW for 8 days in May this year and I wanted to bring back some autographs instead of just pictures. I've decided I'm going to let the characters sign a notebook/sketchbook but I'm not sure on what size it should be. Can someone confirm at least the size of the autograph book they used? Thank you in advance.

The autograph books sold in parks are 4x6, standard photograph size.

If you're interested, I've seen people with the Jr Encyclopedia Disney Characters book. Each character has their own page and they sign right next to their picture. I'm trying it this year for my kids!

I would not go smaller than 4x6. I'd you want to go bigger that's fine too. Some of the characters have somewhat sprawling signatures.
