I was just reminded today about the limits on how many items you can have on a list.
The limits are divided by the type of fields as dictated by the Microsoft article titled “Column Limit Exceeded” Message When You Add a New Column to a SharePoint Services List .
Part of the article:
With Windows SharePoint Services, you can create the following numbers of each column type for each list or library:
| – | 64 Single line of text and Choice (drop-down menu or radio buttons) |
| – | 31 Multiple lines of text and Choice (check boxes (allow multiple sections)) |
| – | 32 Number and currency |
| – | 32 Hyperlink |
| – | 16 Date and time |
| – | 16 Lookup |
| – | 16 Yes/No |
| – | 8 Calculated |
