How To Limit The Word Length Or Number Of Characters In A Cell

I'm using a two column list of words, and I need the first column of words to be exactly 8 letters or less. How can I limit the length of the words in this column to 8 letters?

Thanks

On the Excel Ribbon, Click on the Data Tab. Select Data Validation. Select Data Validation again.

In the allow box, select text length

In the maximum box, select 9

Click ok.
