Step by Step Tutorial: Making Columns the Same Size in Excel for Office 365

Before you dive into resizing your columns, know that this set of steps will guide you through making multiple columns the same width quickly and efficiently.

Step 1: Select the columns

Click on the column headers of the columns you want to resize.

Selecting the columns is the first step in the process. You can click on one column header then hold down the Ctrl key while clicking on others to select non-adjacent columns. Alternatively, click on one column and then shift-click on another column to select all columns in between.

Step 2: Open the Column Width dialog box

Right-click on one of the selected column headers and select ‘Column Width’ from the context menu.

After selecting the columns, right-clicking brings up a menu that offers various options. ‘Column Width’ is what you’re looking for. Clicking this option will bring up a dialog box where you can specify the width for your selected columns.

Step 3: Set the column width

In the Column Width dialog box, enter the desired width and click ‘OK’.

This step is where you make all the magic happen. The column width is measured in characters, so enter a number that reflects how wide you want your columns to be. Keep in mind that the default width for a column is 8.43, which corresponds to the width of approximately 8 characters in the default font size.


Consistent presentationHaving columns of the same size gives your spreadsheet a uniform appearance, which is more visually appealing and easier to navigate.
Improved readabilityUniform column widths mean that data is aligned in a predictable way, making it easier to read and understand.
Efficiency in formattingOnce you know how to quickly resize columns, you can apply that knowledge to future spreadsheets, saving time on formatting.


May not suit all dataUniform column sizes might not be practical if you have varying lengths of text or numbers.
Requires manual adjustmentIf you add or remove data, you may need to resize the columns again to maintain the uniform look.
Can be time-consumingIf you’re dealing with a very large spreadsheet with many columns, resizing them all can take up a considerable amount of time.

Additional Information

When working in Excel for Office 365, there are a few additional tricks you can use to make your spreadsheet stand out. For instance, did you know you can double-click the boundary between column headers to auto-size a column to fit the longest piece of content? This can save you time if you’re less concerned about uniform width and more about ensuring content isn’t cut off.

However, if your goal is to make columns the same size, stick to the manual method described earlier. Also, remember that visual consistency in your spreadsheet is key to making it accessible and easy to use. Consider using bold headers, borders, and cell shading to further enhance readability. And don’t forget, you can apply similar steps to row heights as well, ensuring your spreadsheet is tidy from top to bottom.
