The fastest way to add a line in Word

To insert a line in Word, go to the Insert tab at the top of the ribbon, click Shapes, then select the straight line tool. Click once where you want the line to start, then click again where you want it to end. Word will draw a line between those two points.

If you want a horizontal line that spans the page width without drawing it manually, use the paragraph border method instead. Click in the paragraph where you want the line, go to Home, click the arrow next to Borders, and select Borders and Shading. Choose Bottom Border to place a line under that paragraph. This method is faster for full-width lines and stays in place when you edit text above or below it.

For a line that separates sections of a document, the border method works better than drawing because the line moves with your text as you add or delete content. A drawn line stays in a fixed position on the page.

Key Takeaways

  • Use Insert > Shapes > Line to draw a line at any angle or position on the page.
  • Use Home > Borders to add a horizontal line under a paragraph that moves with your text when you edit.
  • Drawn lines stay in one spot; border lines stay attached to the paragraph they belong to.
  • You can change a line's color, thickness, and style after you create it by right-clicking and selecting Format Shape.

Drawing a line with the Shapes tool

The Shapes method gives you the most control over where your line appears and how it looks. Open the document, click the Insert tab, then click Shapes. A dropdown menu will show you shape options. Look for the straight line icon — it is usually near the top of the list and looks like a straightforward diagonal line.

Click the line tool, then your cursor will change to a crosshair. Click once at the point where you want the line to start, hold down the mouse button, and drag to where you want it to end. Release the mouse button. Word will draw the line between those two points. If you hold Shift while dragging, the line will snap to horizontal, vertical, or 45-degree angles, which is useful if you want a perfectly straight horizontal or vertical line.

After you draw the line, you can move it by clicking and dragging it to a new position. You can resize it by clicking and dragging one of the small squares at either end. Right-click the line and select Format Shape to change its color, thickness, or style — for example, to make it dashed or dotted instead of solid.

Using paragraph borders for full-width lines

If you want a line that runs the full width of the page and stays attached to a paragraph, use the border method. Click anywhere in the paragraph where you want the line to appear — usually below a heading or at the end of a section. Go to the Home tab, then look for the Borders button. It usually shows a small square with lines around it.

Click the arrow next to Borders to open a dropdown menu. You will see options like Top Border, Bottom Border, Left Border, and Right Border. Select Bottom Border to place a line under that paragraph. The line will extend from the left margin to the right margin of your text area.

If you want to change the line's appearance, click the arrow next to Borders again and select Borders and Shading. This opens a dialog where you can choose the line style (solid, dashed, dotted), the thickness, and the color. Make your choices and click OK. The line will update when ready.

Changing line color, thickness, and style

For a drawn line, right-click it and select Format Shape. A panel will open on the right side of the screen. Look for the Line section. You can change the color by clicking the color box, adjust the thickness by moving the Width slider, and select a style like solid, dashed, or dotted from the dropdown menu.

For a border line, click in the paragraph that has the border, then go to Home > Borders > Borders and Shading. In the dialog box, you will see options for Style (the pattern), Color, and Width. Choose what you want and click OK.

When to use a drawn line versus a border

Use a drawn line when you need precise control over placement — for example, if you want a line at an angle, or if you want it to appear in a specific spot that is not directly under a paragraph. Drawn lines are also good for decorative purposes or for creating custom layouts.

Use a border line when you want a line that separates sections of your document and needs to move with your text. If you add or delete paragraphs above a border line, the border stays attached to its paragraph and moves down the page with it. A drawn line will stay in its original position on the page, which can look wrong if text shifts around it.

For most documents — reports, letters, forms — a border line is the better choice because it keeps your layout intact as you edit. A drawn line is better for templates, flyers, or documents where the line needs to stay in one exact spot regardless of text changes.

Removing a line you no longer need

To remove a drawn line, click it once to select it, then press Delete. The line will disappear when ready.

To remove a border line, click in the paragraph that has the border, go to Home > Borders, and select No Border. The line will be removed from that paragraph.

Frequently Asked Questions

Can I make a line go across the entire page width?

Yes. Use the border method — click in a paragraph, go to Home > Borders > Bottom Border. The line will span from the left margin to the right margin. A drawn line will only go as far as you drag it, so it is harder to make it span the full width.

How do I make a line dashed or dotted instead of solid?

For a drawn line, right-click it, select Format Shape, find the Line section, and click the dropdown next to Dash type. For a border line, click in the paragraph, go to Home > Borders > Borders and Shading, and choose a dashed or dotted style from the Style list.

What happens to my line if I add text above it?

If you used a border, the line moves down with the paragraph it is attached to. If you drew the line manually, it stays in the same spot on the page, which can leave it floating in the middle of text. This is why borders are better for documents you plan to edit.

Can I change the color of a line after I create it?

Yes. For a drawn line, right-click it and select Format Shape, then click the color box in the Line section. For a border, click in the paragraph, go to Home > Borders > Borders and Shading, and choose a new color from the Color dropdown.
