No big enough I find. A4 sheet music is just what I'm used to. Being able to write extra notation in (finger markings for piano or practice marks) with a pencil is just so easy. Also being able to have two sheets side by side. On an iPad you're limited to one. Sure, you could buy two, but then what if your score is 4 pages long? You have to either do split PDFs or swipe multiple times on the other one or something. Edit: I'm sure an iPad pro might be good size and resolution wise but I couldn't justify the cost just for sheet music. Plus the multi page issue.
