Why Should You Autofit?

Remember when you were a kid and tried to fit into your older sibling’s shoes? They were either too big or too small, right? In the world of Excel, columns are those shoes. And data? That’s you. Autofitting columns ensures your data fits perfectly, making it more readable and neat.

Steps to Autofit Columns in Excel for Office 365

  1. Opening Your Excel Document – Open Excel (Office 365 version). Open the document you want to work on. This could be a budget sheet, a list of your favorite movies, or anything else.
  2. Selecting Columns – At the top of your Excel sheet, you’ll find letters representing each column: A, B, C, etc. Click on the letter of the column you want to autofit. Want to select multiple? Just click and drag!
  3. Accessing the Format Menu – Once you’ve chosen your column(s), choose the Home tab at the top of the screen, then click on Format in the Cells section of the ribbon. A dropdown menu appears.
  4. Choosing Autofit – From the dropdown menu that you should now see, simply click on the AutoFit Column Width option, which should automatically resize the selected columns so that data within those columns is visible.
  5. Manual Adjustments (if needed) – Maybe autofit did its job, but you want to tweak the size just a smidge. No problem! Hover between the column letters until your cursor turns into a line with arrows. Drag it to adjust the column width as you please.

Pros and Cons of Autofitting


  • Easy Peasy: With just a few clicks, your columns adjust to fit your data. Simplicity at its best.
  • Clean Look: Autofitting gives your sheet a neat appearance. It’s like giving your data a fresh haircut!


  • Not Always Perfect: Sometimes, autofit might not get the width just right. But hey, no worries! You can always make manual adjustments.
  • Uniformity Issues: If you have one super long piece of data in a column, autofitting might make the rest look spaced out. But then again, manual tweaks can come to the rescue.
