MS Access - 255 Column Limit. Published 09/12/2002 01:02 PM | Updated 11/22/2011 06:19 PM. Does Microsoft Access have a limit on the number of columns that can be in a table? Microsoft Access (w/ the JET Engine) is able to display no more than 255 columns in a table.
Columns per non-wide table - 1024. This affects the number of custom attributes you can add to an entity - once you get up around the 1000+ mark, you'll hit an error. Joins - Table Sources. There is also a limit on the number of tables (256) that can be used as sources for a join in a single query.
