Need help choosing between the 11" and 13" iPad for note‑taking 📱✍️

Hey everyone, I’m planning to buy an iPad mainly for handwritten notes (DSA, system design, tech learning, PDFs, etc.), plus some light YouTube and productivity apps like Notion/Obsidian.

I’m confused between the 11‑inch and 13‑inch iPad:

11" seems more portable and easier to hold for long note‑taking sessions

13" looks great for bigger diagrams, split‑screen, and reading PDFs

For those who use an iPad a lot for notes and studying, which size do you recommend and why?
