About the number of columns in a SharepointList

Question

What is the maximum number of columns in a list in SharepointList?

Answer 1

Hi @田畑俊貴 / TABATA，TOSHIKI,

Each column added to a list consumes a number of bytes. Both SharePoint on-Prem and SharePoint Online have a limitation of 8,000 bytes per row. The total number of bytes consumed cannot exceed 8000.

For details on how much space each kind of field consumes, see Column limits.
