I don't know how you do it, but I will quickly show an easy way to adjust the height of rows in excel.
Then you will need to right click a number.
Then you should select "Row Height" from the menu that appears.
The default height is generally 15. So, if you want it to be twice as tall you should go to 30.

How to adjust the column width?
Then you should right click a letter.
Then you should select "Column Width"
My default width is 8.43 (not 100% sure this is normal).
Hope this helped.
