How Do You Dimension an Angle in SketchUp for Free?

SketchUp is a popular 3D modeling software that offers a wide range of tools and features to create detailed and accurate models. If you’re working on a project that requires precise angles, it’s essential to know how to dimension angles in SketchUp. In this tutorial, we will guide you through the steps of dimensioning an angle in SketchUp for free.

Step 1: Select the Angle Tool

To begin, open your SketchUp model and navigate to the toolbar. Locate the “Angle” tool and click on it. Alternatively, you can access this tool by selecting “Tools” from the menu bar and choosing “Protractor” from the dropdown menu.

Step 2: Measure the Angle

Once you have selected the Angle tool, move your cursor to the desired vertex of the angle you want to measure. Click on this vertex point to set it as the starting point of your angle measurement.

Next, move your cursor along one of the adjacent edges of the angle until it aligns with the other edge forming the angle. Click again to complete your measurement.


  • Snapping: To ensure accurate measurements, make use of SketchUp’s snapping feature. This allows your cursor to snap onto specific points or edges while measuring an angle.
  • Precision Input: If you require a specific angular value rather than just measuring an existing angle, you can enter precise measurements manually using SketchUp’s measurement input box.

Step 3: Displaying Dimension Labels

To display dimension labels for your measured angles, navigate to “Window” in the menu bar and select “Default Tray” from the dropdown menu. Check the box next to “Dimensions” to enable dimensioning tools.

Step 4: Dimensioning the Angle

With the Dimension tool enabled, move your cursor over the measured angle. SketchUp will automatically detect and highlight the angle.

Click on it to create a dimension label. You can then move and position this label as desired.


  • Editing Labels: To edit dimension labels, select them with the Select tool and use SketchUp’s text editing features located in the “Entity Info” panel.
  • Styling Labels: You can further enhance your dimension labels by adjusting their font size, style, color, or adding additional callouts using SketchUp’s text formatting options.

Congratulations! You have successfully dimensioned an angle in SketchUp for free. By following these steps, you can accurately showcase angles in your models and ensure precise measurements for your projects.


In this tutorial, we learned how to dimension an angle in SketchUp for free. We explored how to use the Angle tool to measure angles accurately, display dimension labels, and customize them according to our preferences. Remember, proper measurement and annotation of angles are essential for creating detailed and professional models in SketchUp.
