Google Docs is a powerful online word processor, but many users don’t realize it offers vertical rulers to help align text, images, and tables more precisely. While the horizontal ruler is visible by default, the vertical ruler needs to be enabled through specific settings.

This guide will show you how to turn on the vertical ruler in Google Docs, along with tips for using it effectively for formatting and layout.

What Is the Vertical Ruler in Google Docs?

The vertical ruler appears along the left-hand side of the document and helps you:

Measure top and bottom margins
Align headers, images, and tables
Create precise spacing for professional documents
Maintain consistent layout throughout the page

Unlike the horizontal ruler, which measures width, the vertical ruler ensures your height alignment is accurate.

Step 1: Open Your Google Docs Document

Go to Google Docs in your web browser.
Open an existing document or create a new one.

⚠️ Note: The vertical ruler is currently only available in Google Docs on desktop. It does not appear in mobile apps.

Step 2: Go to View Options

Click on the View menu at the top of the screen.
Hover over or click Show ruler.

This will toggle the horizontal ruler by default.

Step 3: Enable the Vertical Ruler

After enabling the ruler, click File → Page Setup.
In the Page Setup dialog box, ensure your page orientation is set to Portrait.
The vertical ruler should now appear along the left side of the page.

✅ Tip: If you don’t see it, make sure your browser window is maximized. The vertical ruler sometimes hides in narrow browser windows.

Step 4: Using the Vertical Ruler

The vertical ruler helps you:

Adjust Top and Bottom Margins: Click and drag the blue margin indicator along the ruler.
Align Objects: Use it to line up images, tables, or drawings.
Check Spacing: Verify that text or tables maintain consistent spacing from the top and bottom edges.

Tips for Using Rulers in Google Docs

Combine with the Horizontal Ruler: Enables precise layout in both directions.
Use Guides for Tables and Images: Helps with professional formatting.
Snap to Margins: The ruler will snap elements to your preset margins for consistent alignment.
Zoom In for Accuracy: Increase zoom to better position objects using the vertical ruler.
