Viewing and Adding Table Records
Adjusting a column width in Access is similar to Microsoft Excel. By default, each column in Access is 15.6667 characters wide. Each individual column can be enlarged to 363 characters wide.
When entering records, you may need to resize columns to view the information as it is being typed. The width of an address column, for example, might be smaller than the actual address. You can adjust the column width of any field so it is wide enough to view the complete field entry.
In Access, you can adjust column width manually, use AutoFit, or use the menu bar.
