How to Underline Blank Space in Word: A Step-by-Step Guide

Underlining blank spaces in Microsoft Word can be a bit tricky, but it’s definitely doable! Whether you’re creating a fill-in-the-blank document or just want to visually separate text, underlining those pesky blank spaces is a simple task once you know how to do it. So, let’s get down to business and underline those spaces!

Step by Step Tutorial: How to Underline Blank Space in Word

Before we dive into the steps, it’s important to know why you might need to underline blank spaces. Maybe you’re preparing a worksheet and want to create lines where people can write their answers, or you’re designing a document that requires some visual separation without using actual text. Whatever the reason, following these steps will help you achieve that goal.

Step 1: Place Your Cursor

Place your cursor where you want to start underlining the blank space.

For this step, it’s crucial to place your cursor exactly where you want the underline to begin. If you’re working within a sentence or a word, make sure your cursor is blinking in the right spot.

Step 2: Press Shift and the Underscore Key

Press and hold the Shift key, then press the underscore (_) key repeatedly to create an underline.

As you press the underscore key, you’ll see a line being drawn across the page. This will create a visual underline without any text above it. Keep pressing until you’ve reached the desired length of your underline.

Step 3: Adjust the Underline Length

Use the arrow keys to adjust the length of the underline if necessary.

Sometimes, you might underline a bit too much or too little. No worries—just use the left and right arrow keys to position the cursor where you need to either continue underlining or backspace to remove excess underlines.

After completing these steps, you’ll have a beautifully underlined blank space in your Word document that’s ready for whatever purpose you need it for.

What Happens Next

Once you’ve underlined your blank space, the line will behave just like any other text. You can format it, change its color, or even apply different styles of underlining if you want to get fancy.
