How to Change Strikethrough Line Thickness in Acrobat Pro DC
Product
Adobe Acrobat Pro DC
Device & OS
not provided
Scenario
Reviewing and commenting on a PDF document where a heavier or more visible strikethrough line is needed for emphasis.
Observed behavior
The color of the strikethrough can be customized, but the line thickness control is grayed out or entirely unavailable because standard PDF strikethrough annotations scale automatically with the text size.
Before you start

Ensure you have the 'Comment' or 'Drawing' tools enabled in your PDF editor, as you will need to utilize shape annotations to bypass this limitation.

Solution 1Recommended

Use the Line Drawing Tool for Custom Thickness

Since standard text strikethrough annotations do not support thickness adjustments, using a line shape is the best workaround to achieve the exact look you want.

In the PDF specification, a standard text strikethrough is a markup annotation tied directly to the font size of the text it covers. Because of this, Adobe Acrobat disables the thickness slider. By using a drawing tool instead, you gain full control over the line's weight, color, and opacity.

1
Select the Line Tool

Open the 'Comment' pane or go to 'Tools' > 'Comment'. Click on the Drawing Tools icon and select the 'Line' annotation tool.

2
Draw the Strikethrough

Hold down the Shift key (to keep the line perfectly horizontal) and drag your cursor over the text you wish to strike out.

3
Adjust Line Properties

Right-click the line you just drew and select 'Properties'. Navigate to the 'Appearance' tab and adjust the 'Thickness' slider to your preferred weight. Click 'OK' to apply.

Use the Line Drawing Tool for Custom Thickness
Pro Tip: If you need to use this thicker line repeatedly, right-click the adjusted line and select 'Make Current Properties Default'. Every new line you draw will now have the same thickness.

Frequently Asked Questions

Why is the thickness option grayed out for standard strikethroughs in Acrobat?

Standard PDF text annotations, such as strikethroughs and highlights, are defined by the PDF specification to automatically scale with the underlying text size. Because they are dynamically linked to the font, manual thickness adjustments are disabled by design.

Can I change the color of a standard strikethrough in a PDF?

Yes. While the thickness is locked, you can right-click the standard strikethrough annotation, select Properties, and choose a different color or adjust the opacity from the Appearance tab.

Is there a plug-in or setting to force standard strikethroughs to be thicker?

No, there are no native settings or standard plug-ins to alter the base behavior of text markup annotations. Using a line drawing shape remains the primary and most reliable workaround.

Will drawn line annotations print accurately like normal text markups?

Yes, as long as you ensure your print settings are configured to print 'Document and Markups'. The custom-drawn lines will print exactly as they appear on your screen.
