how do i change the default size in base

also, when i run my query, i have to widen the columns to see the data. then i can’t seem to figure out how to save the query with the new column widths, because when i run it again, it doesn’t save them.

What do you mean by “size”? The column width?

Although this feature does not work for queries, you can save column widths for tables, views and Table controls in Forms. After adjusting the column width, save the database (not just save the table). There is no prompt to say that it’s changed. This also seems to work (most of the time) with Save As.
