Quickly Resize Multiple Columns or Rows at Once in Excel

Auto-Fit Multiple Rows or Columns to the Size of the Data in Them

1. Select the entire columns or rows that need to be resized. To do this, left-click the header, either where it says A, B, C, etc. or 1, 2, 3, etc.,  and hold the mouse button down while you drag across to select more columns or rows.
   
2. Double-click in the header in between one of the selected columns or rows.
   
   Now, the columns have been made large enough so that you can see everything in them and it took only seconds to make this happen.

Doing this with rows works the exact same way except you select the rows and double-click in the header in between them.

Resize Multiple Rows or Columns at Once

1. Select the columns or rows like we did in the previous example.  Left-click the header for the columns or rows and drag the mouse across to select multiple rows or columns.
   
2. Left-click the mouse button in the header between the columns or rows that you selected and drag the mouse to the left and right for columns and up and down for the rows to adjust the size of all of the selected columns at once.
   
3. That's it.
   

You can adjust the rows in the exact same way.

Notes

This may seem trivial, but it will save you a lot of time when dealing with large data sets, especially imported data or spreadsheets from other people.
