As far as "more space", you should think of the QR code as a "link", or a "shortcut" to your URL. Clicking the QR code brings the user to web site; once they're there, you have as much space as you want.

Solution 2:

QR codes come in various standardized sizes, but the largest is version 40 which can store about 2,953 bytes. 2953 character is the maximum that you can store within a single QR code
