List columns or Site columns in SharePoint?

We have two (2) types of columns in SharePoint:

• List Columns
• Site Columns

One is created at the List/Library level (list columns), and the other one at the Site level (site columns). From a functionality perspective, they do the exact same thing. From a “re-usability” perspective… not so much…

The only difference between the two, Site Columns are “shared” between sites, but only hierarchically. See that as crescendo 🙂

List columns are created at the list/library level and won’t be available outside that list/library. So you’ll have to manage them separately. Site columns are re-usable from the parent site crescendo to all the subsites.
