Product
Microsoft Word
Device & OS

Scenario
Creating or filling out a document form that relies on continuous underscores to represent fillable blank fields.
Observed behavior
The underscore characters used to create blank lines disappear or are completely invisible on the screen, often due to tight line spacing or document layout settings.
Before you start

Before making structural changes to your document, check the Print Preview mode. Tight line spacing can sometimes hide underscores on the screen while they still print perfectly fine.

Solution 1Recommended

Use Table Cells with Bottom Borders for Form Fields

This is the most reliable method for creating stable form layouts, ensuring fillable lines always remain visible and do not shift when users type.

Typing underscores manually often causes text wrapping issues and misalignment when someone fills out the form. Using a borderless table with specific bottom borders creates a clean, professional, and highly stable fillable area.

1
Insert a layout table

Go to the 'Insert' tab on the top ribbon, click 'Table', and select the number of rows and columns needed to organize your form labels and blank fields.

2
Remove all existing borders

Click the four-way arrow icon at the top-left of the table to select the entire table. Navigate to the 'Table Design' tab, click the 'Borders' dropdown, and select 'No Border'.

3
Apply bottom borders to fillable cells

Highlight only the specific cells where users are supposed to type their answers. Click the 'Borders' dropdown again and select 'Bottom Border' to create a solid, stable line.

Use Table Cells with Bottom Borders for Form Fields
Pro Tip: You can adjust the column widths by dragging the cell boundaries to make the blank lines exactly as long as you need them to be.

Frequently Asked Questions

Why do my underscores disappear when typing in Word?

Underscores often disappear because the paragraph's line spacing is set to a fixed, tight value (such as 'Exactly' with a small point size). This causes the text boundaries to overlap, effectively cutting off the bottom portion of characters like underscores on your screen.

Do hidden underscore lines still print if I can't see them?

Yes, in many cases. Underscores that are hidden by tight line spacing on the screen will frequently still render correctly when sent to a printer. You can verify this by checking the document in Print Preview mode before making adjustments.

Is there a better way to make a fillable line than typing underscores?

Yes. The most stable and professional method is to insert a table, remove all of its borders, and then apply only a bottom border to the cell where the user needs to write. This prevents the line from shifting, breaking, or pushing text out of alignment when information is entered.
