Cynthia Jul 13, 2026

Diagonal guides are an essential tool in Adobe InDesign for aligning and spacing elements across your layout. Creating them allows you to establish a visual hierarchy and enhance your design's overall aesthetic. Here's a step-by-step guide on how to make diagonal guides in InDesign that will help you master this technique.

Understanding InDesign's default grid system is crucial before we dive into creating diagonal guides. The program automatically creates horizontal and vertical guides based on your document's margins and columns. However, these guides might not always accommodate the design you have in mind. That's where creating custom diagonal guides comes in handy.

Creating the First Diagonal Guide

The process begins by defining the angle you want your guide to follow. Let's start with a 45-degree angle, which is a common choice for diagonal designs.

First, open your InDesign document and ensure that your rulers are visible. If not, press Ctrl+R (Windows) or Cmd+R (Mac) to display them. Rulers appear at the top and left sides of your document.

Setting the Rotate View Option

To create a 45-degree diagonal guide, you'll need to rotate your view. This step isn't strictly necessary, but it helps visualize the angle more accurately.

1. Click the Rotate View tool in the toolbar. It's located near the rulers and looks like a rotated rectangle.

2. Hold down the Shift key and click on the grid intersection where you want to set the 45-degree angle. This will snap the view to that angle.

Creating the Diagonal Guide

Now that your view is set to 45 degrees, it's time to create your guide.

1. Click and drag the Rule of Thirds tool (*) from the rulers onto your document. This will create a diagonal guide based on the angle you've set.

2. You can adjust the length of the guide by dragging one of its ends. Alternatively, you can adjust both ends simultaneously to create a symmetrical guide about the center point.

Creating multiple diagonal guides helps establish a symmetric and harmonious layout. Let's discuss how to create additional guides based on the first one we've made.

InDesign allows you to copy and rotate existing guides to create new ones quickly. This process saves you time and ensures that your new guides are accurately aligned with your first guide.

Copying and Rotating Guides

Let's create a guide with a 90-degree offset from our initial 45-degree guide.

1. Click on the Selection tool (black arrow) in the toolbar.

2. Hover over your existing guide until the cursor changes to a double-headed arrow. This indicates that you can rotate or scale the guide.

3. Hold down the Option key (Mac) or Alt key (Windows) and click and drag the guide to rotate it 90 degrees. Holding the modifier key prevents InDesign from scaling the guide while you rotate it.

Setting the Slope of Diagonal Guides

In case you need a diagonal guide with an angle other than 45 or 90 degrees, you can set the slope manually. This process is slightly more involved but still straightforward.

1. With the Selection tool active, click on your guide to select it.

2. In the Control panel (or the Transform panel if it's not visible), you'll see the Slope option. This value represents the angle of your guide. Enter your desired angle in degrees. For example, enter 23.43 for a 23.43-degree guide.

That's it! You've now mastered creating diagonal guides in InDesign. This skill will significantly improve your layouts and help you create visually appealing designs. Start experimenting with different angles and combinations of guides to see what creative solutions you can come up with. Happy designing!
