Insert a Zigzag Line in Word: Steps and Formatting

To insert a zigzag line in Microsoft Word, go to Insert > Shapes, choose Freeform: Shape in the Lines section, click alternating high and low points on the page, then double-click to finish. You can then change its color, thickness, and position from the Shape Format tab. For a loose, hand-drawn effect, choose Scribble instead.

Choose the right way to draw a zigzag

Word does not always present a dedicated zigzag-line button in its Shapes gallery, and gallery options can vary by version. A freeform line is the most dependable way to create a neat zigzag: each click marks a corner, so you control how many peaks it has and how far apart they are. Scribble is better when you want an irregular, handwritten stroke rather than evenly planned corners.

Before drawing, consider what the line needs to do. A small divider between sections, a decorative accent, and a line that traces a chart all need different proportions. A zigzag made from five sharp turns can look clear at a large size but cramped when reduced to fit beside text. For a compact divider, use fewer, wider turns; for a long accent, repeat more turns while keeping their height consistent.

Freeform: Shape: best for deliberate, straight-sided peaks and valleys.
Scribble: best for a casual hand-drawn mark; its path follows the mouse or trackpad movement.
Separate line segments: useful if you need to adjust individual sections, though they take longer to align and may need grouping.

These methods insert a drawing object, not a typed character. That distinction matters: a drawn line can be resized and formatted independently, while a text character moves with the surrounding words and may change appearance with the font.

Draw a controlled zigzag with Freeform

In Word for Microsoft 365 on Windows, use these steps:

Click in the document near the place where the line should appear. If the line belongs in a particular paragraph, placing the cursor there first can make it easier to keep the drawing near the right text.
Select Insert > Shapes. In the gallery’s Lines section, point to or select Freeform: Shape. If your gallery shows a different label, look for the freeform tool that creates straight segments rather than the Scribble tool.
Click once to set the starting point. Click again at each alternating high and low point. Each click creates a corner and a straight segment between points.
After the final point, double-click to complete the drawing. Avoid clicking back on the starting point unless you intend to close the shape.
Select the finished line to display its sizing handles and the contextual Shape Format tab.

For example, to make a simple three-peak accent, click a low starting point, then a high point, then a low point, and continue alternating until you reach the desired endpoint. Keep the horizontal spacing between clicks similar to create a regular rhythm. Zooming in can help with precise placement, but remember that the shape’s printed size is determined by its position and dimensions on the page, not the zoom level.

Word for Mac also provides drawing shapes through Insert > Shapes. The gallery and contextual formatting controls can look slightly different between Mac releases, but the basic method is the same: select a freeform drawing tool, click the alternating points, and finish the line. If a particular freeform label is not visible, use the gallery’s tooltips or select Scribble for a hand-drawn alternative.

Draw a freehand line with Scribble

Choose Insert > Shapes > Scribble when you want to draw continuously rather than place exact corners. Click and hold the mouse button, move the pointer up and down as you travel across the page, and release when the line is complete. A mouse often makes this easier than a trackpad, especially for a long line.

Scribble can be quick, but the result depends on pointer movement. A small wobble in your hand can create extra bumps, and a slow movement may make a sharper corner than intended. If the line looks untidy, undo the drawing and try again with larger, steadier movements, or use Freeform: Shape for more predictable angles. You can also zoom in while drawing for control, then zoom back out to judge the overall appearance.

For a very regular design, drawing separate straight segments is another option. Insert a line shape for each side of the zigzag, then set the endpoints so adjacent lines meet. This gives you control over every segment, but tiny gaps or overlaps can appear if the endpoints are not aligned. If you choose this approach, select all the segments and group them once they are positioned, so they can be moved together.

Change the line’s color, weight, and style

Click the zigzag to select it, then open Shape Format. Use Shape Outline to choose a color, line weight, or dash pattern. The weight setting changes the stroke thickness; a heavier stroke tends to remain visible when printed or viewed at a distance, while a thin stroke is less visually prominent. Use a color with enough contrast against the page and nearby text.

Common formatting choices include:

Color: choose a color that fits the document’s design and remains distinguishable in grayscale if readers might print it without color.
Weight: increase the thickness for a prominent divider or reduce it for a subtle decoration.
Dashes: use a dashed or dotted outline for a different visual effect, but check that the short segments remain legible around each corner.
Effects: effects such as shadows can make a decorative line stand out, but are usually unnecessary for a simple separator.

A freeform drawing may sometimes finish as a closed shape, especially if the endpoint meets the start point. If Word displays an interior fill, select Shape Fill > No Fill on the Shape Format tab, then adjust Shape Outline. If you only see outline controls, the object is already being treated as a line, so there is no fill to remove.

Position the zigzag beside text or in a page layout

Word treats a drawn zigzag as a floating drawing object or an object associated with the text around its anchor. If it moves unexpectedly when you edit nearby paragraphs, select it and look for the layout or text-wrapping options. Choosing an appropriate wrapping style can let text sit beside the line or keep the line separate from the paragraph. For a simple divider between paragraphs, placing it on its own line can be easier to manage than wrapping text around it.

To move the drawing, select its outline and drag it. To resize it, drag a corner handle; corner resizing generally changes the height and width together. Dragging a side handle changes one dimension and can flatten the zigzag. If the line becomes too shallow, resize from a corner or adjust the vertical spacing of its points by redrawing it. Avoid dragging a middle handle when you want to preserve the original proportions.

For precise placement, use the position and size controls available on the Shape Format tab, where your Word version exposes them. If the line must stay aligned with a heading or a table, consider placing it in the same table cell or paragraph area rather than positioning it as an unrelated object elsewhere on the page.

Use a zigzag as a divider, annotation, or diagram

A zigzag has no single meaning in a Word document. It can be a decorative divider, a visual cue for a change in topic, or a simplified path in a diagram. If it represents data, a process, or a warning, label it or explain it in nearby text so readers do not have to guess what the turns signify. A decorative mark should not be the only way important information is communicated.

For a divider, leave enough blank space around the shape so it does not collide with letters or paragraph borders. For an annotation, use a nearby label and make sure the line points clearly to the relevant item. For a diagram, use Word’s other shapes and connectors where appropriate; a freeform zigzag is visually flexible, but it does not automatically attach to another shape like a connector may.

If you need the same zigzag in several places, copy and paste the finished shape, then reposition each copy. This preserves its appearance better than redrawing it each time. If the copies need different dimensions, resize them after pasting and inspect the corners to make sure they still look consistent.

Fix common drawing problems

If the line does not appear, check whether the shape was completed and whether its outline color blends into the page. Select near the line’s path; a thin stroke can be difficult to click. You can also use the Selection Pane, when available in your Word version, to locate drawing objects by name or select an item that is partly covered.

The shape looks like a filled polygon: it may have been closed. Set Shape Fill to No Fill, or redraw it and finish without returning to the starting point.
The line moves with the wrong paragraph: check its anchor and text-wrapping settings, or place it in the paragraph or table cell it should accompany.
The zigzag is uneven: redraw with Freeform: Shape and keep the click spacing and vertical distance consistent.
It is hard to select: zoom in, click directly on the stroke, or use the Selection Pane if available.
It prints faintly: choose a darker outline or increase its weight, then check Print Preview.

A red or blue wavy underline beneath typed words is a different feature. It is Word’s proofing display for possible spelling or grammar issues, not a decorative shape in the document. Drawing a zigzag will not change proofing marks, and proofing marks generally are not printed as part of the page. If your goal is to show a red wavy underline beneath a word, use Word’s spelling or grammar tools rather than inserting a freeform line.

Frequently Asked Questions

Is there a one-click zigzag line in Word?
Some shape galleries or releases may show a preset zigzag, but it is not consistently available under the same name. Freeform: Shape is a reliable way to create a controlled zigzag using clicks at alternating points.

How do I make a straight, even zigzag?
Choose Freeform: Shape and click each corner instead of drawing by hand. Keep the horizontal distance between clicks and the vertical height of peaks similar. Use the same outline weight throughout.

Can I make a zigzag line in Word on a Mac?
Yes. Open Insert > Shapes, choose an available freeform drawing tool, and place the points in sequence. The gallery labels and some formatting controls can differ slightly from Word for Windows.

How do I make the zigzag thicker or change its color?
Select the line, open Shape Format, and use Shape Outline to change the outline color and weight. If the drawing is a closed shape, remove its fill with Shape Fill > No Fill.

Why does Word show a red zigzag under my word?
That is a proofing indicator for a possible spelling issue, not a shape you inserted. It is normally an on-screen aid rather than printed artwork. A drawn zigzag line is a separate object that you can format and position.
