How to delete horizontal lines in Word header: The line at the top cannot be removed

The horizontal line at the top of the header is usually the lower border of the paragraph, and will remain even if the header text is deleted. This article explains its origin, gives the steps to clear borders, handle multiple sections and template styles in Word, and explains how to check after deletion.

Key points of this article

  • The horizontal line at the top of the header is mostly the lower border of the last paragraph in the header. After deleting the text, the paragraph is still there and the line is retained.
  • The idea is to clear paragraph borders instead of continuing to delete text. Text and borders are two settings.
  • If the document is divided into sections, the header of each section must be checked separately, otherwise changing only one section will leave lines in other sections.
  • If the line is a graphic that can be clicked individually, delete the graphic directly; if it comes from a template style, change the style itself so that it does not reappear.

Many people delete the text in the header, but there is still a horizontal line at the top. If they change the page and look at it, it is still there, so they think it was not deleted completely, and deleting the text repeatedly has no effect. This line is usually not text, but the lower border of the header paragraph. After the text is deleted, the paragraphs remain and the borders remain.

This article is written for people who edit papers, reports, and contracts in Word to explain clearly where this horizontal line comes from, how to delete it in Word, and how to check after deletion. This article only deals with the horizontal line at the bottom of the header. The lines next to the page numbers and the lines in the footer have similar processing ideas, but the sources may be different, and will be explained separately in the article. After reading this, you should be able to identify what the line in your hand is and delete it.

Before you start: Confirm these points first

Spending a minute or two to judge before taking action can avoid deleting the wrong things and avoid detours.

  • Confirm the type of line. The horizontal line in the header is usually located immediately below the header text. When you point the cursor in, you can see that it belongs to a certain paragraph. If the lines can be individually selected and dragged, it is a graphic and is handled differently.
  • Confirm whether the document is divided into sections. Papers and reports are often divided into chapters. The headers of different sections may be linked to each other or may be set separately. Only the current page will be changed, and the lines in other sections will remain.
  • Save a separate copy first. It is not easy to completely undo changes to borders and styles. Keep the original files so you can compare them if there is a problem.
  • Turn on paragraph mark display. You can see the symbol of the empty paragraph, which makes it easy to confirm the paragraph where the cursor is located and determine which paragraph the line is under.
  • Pay attention to the template source. If it appears again after deleting it, it is probably because the header style in the template has a border. It will only be deleted in the current document and will be restored when a new paragraph is created.

Steps to delete the horizontal line at the top of the header in Word

The following steps apply to most header lines. Do it in order and stop when the line has disappeared.

  1. Enter the header editing state. Double-click the header area at the top of the page, the header text will become editable, and the main text will become lighter.
  2. Delete header text and redundant blank lines. Delete unnecessary text and blank lines, leaving only one paragraph, and place the cursor in this paragraph.
  3. Confirm which paragraph the line belongs to. Display paragraph mark to see if the horizontal line is under the paragraph where the cursor is located. If yes, proceed to the next step.
  4. Clear the bottom border of the paragraph. Open the paragraph's border settings and select no border, or just cancel the bottom border. This step will remove the horizontal lines and keep the text.
  5. If the line is still there, change the paragraph style back to the text. The header style may come with a lower border. After changing back to the text style, the customized border will be cleared.
  6. Exit header editing and check section by section. Go back to the main text and scroll through the document to see if there are lines at the top of the headers of each section. If divided into sections, repeat steps 1 to 5 for each section.

❓ Frequently Asked Questions (FAQ)

1. After deleting the header text, the horizontal line is still there. Did it not be deleted completely?

uncertain. The horizontal line is usually the lower border of the last paragraph in the header. After the text is deleted, the paragraph is still there, and the border is retained. At this time, you should clear the paragraph borders instead of continuing to delete text.

2. Are the lines next to page numbers the same as the horizontal lines in the header?

no the same. The line next to the page number may come from a footer paragraph border, page number formatting decoration, or a text box. Before processing, click to confirm which category it is, and then decide which method to use.

3. How to delete a line in the footer?

The method is the same as for headers. Double-click the footer area to enter editing, find the last paragraph of the footer, and clear its lower border. If the document is divided into sections, the footer should also be checked section by section.

4. What should I do if it reappears next time I open it after deleting it?

Mostly templates or paragraph styles with borders. Change the paragraph style back to the text style, or cancel the lower border of the header style in the style settings, and then check whether horizontal lines still appear in the new paragraph.

5. The line only appears in a certain section but not in other sections. Why?

This is usually caused by segmentation. The header of a certain section may have canceled the "link to the previous section" and set a separate border. Go to the header section by section, find the section with lines, and clear the border alone.

📝 Summary

The horizontal line at the top of the header is mostly the lower border of the paragraph, and deleting text will not remove it. Enter header editing, clear the border of the last paragraph, and then check section by section to delete the horizontal lines.
