The usual approach to building a checklist in Word is to pick a bullet style that looks like a square, type your items, and call it a day. That works fine for a quick internal list, but it breaks the moment you need to send the file to someone else, convert it to PDF, or have multiple people fill it out digitally. The symbols shift, fonts drop out, and you end up with a document that looks like a mess on another computer. The real problem isn't the idea of a checklist; it's the mismatch between what you want the list to do and the tool you're using to build it. Before you do anything, you have to decide what the checklist actually is. In Word, there are effectively two types, and confusing them is the source of most of the headaches I see in thread replies. The first is a static list. This is just text with a symbol. It prints fine, it looks clean, but you can't interact with it. The second is a form field. This is an actual interactive control that users can click to toggle a checkmark. It's more robust for distribution, but it requires a specific workflow to set up correctly. If you want a simple list that will survive a print job or a PDF export without falling apart, you should use the built-in Dropdown List or Checkbox controls from the Developer tab. Here is the straightforward process. First, enable the Developer tab. Go to File, Options, Customize Ribbon, and check the box for Developer. It stays there permanently once you've done it. Next, position your cursor where you want the checklist to start. Click the Checkbox Form Field button in the Controls group. This inserts a small, uncheckable box. Type your list item text immediately after it. Press Enter to go to the next line, and repeat. To protect the document so users can only check the boxes and not delete the layout, click Restrict Editing on the Developer tab, check the box for Allow only this type of editing in the document, and select Filling in forms. Finally, click Yes, Start Enforcing Protection.

This method creates a functional checklist that takes about five minutes to set up for a standard ten-item list. The key detail most people miss is the properties button. If you double-click the checkbox form field, you can change the character that appears when it's checked. By default, it's a checkmark, but you can change it to an 'X' or leave it blank. This is useful if you are preparing a document for a specific department that prefers a different marking convention. I ran into a specific edge-case last year with a compliance audit document. The client needed a checklist that would be emailed to twenty different regional managers, each of whom would fill it out and return it. I used the form field method. The problem arose when some users opened the document in Word for the Web. The form controls were missing, and the checkboxes appeared as blank squares with odd borders. The workaround was not to use Word for the Web, but to export the final protected document to a fixed PDF format using the Save As function and selecting PDF with the Standard optimization. The PDF preserved the interactive fields for any reader that supports forms, and it eliminated the version incompatibility between Word 2016, 2019, and Microsoft 365. It added about three minutes to the process but prevented a week of back-and-forth emails. There are significant downsides to this approach. Form fields do not work in the mobile apps for iOS or Android; users on those devices will see the boxes but cannot click them. If your checklist needs to be filled out on a phone, you should use a static image or a table with a symbol font instead. Also, if you need to count the number of checked items automatically, form fields will not give you a sum. You would need to use a different tool like Excel or a dedicated form builder. The form field method is strictly for data collection, not for calculation.

For a purely visual list that never needs to be interactive, the fastest path is to use the Bullets dropdown in the Home tab, select Define New Bullet, and choose a symbol font like Wingdings. This creates a static list that is fully editable and prints reliably. It takes thirty seconds to set up, but you lose the ability to have a user 'check' the item digitally. Choose the method based on whether the checklist is a document to be read or a form to be completed.
