Howdy MickeyMac!
By size, I think you're asking about the physical dimensions. It's 9.5" x 7" x 2" and I'd say it weighs roughly a pound (think of a small Franklin planner). Page count is 286 + the special pages. Ideally, I think they'd like folks to take them to the parks. I probably will, but we'll have a diaper bag and a stroller with us anyway. If we didn't, I think it's probably too big to carry around all day.
