Working with Adobe Illustrator opens up a multitude of creative possibilities. Two functional tools that can help you make your designs more precise and appealing are the eyedropper and the measuring tool. With the eyedropper, you can quickly and easily sample colors, while the measuring tool provides you with accurate dimensions of your elements. In this guide, you'll learn how to effectively integrate both tools into your workflow.
Key Takeaways
- The eyedropper allows you to sample colors from your design or images and save them as swatches.
- The measuring tool lets you determine precise measurements of lines and objects in the workspace.
- Both tools are found in the toolbar and help optimize your workflow in Illustrator.
Step-by-Step Guide
Using the Eyedropper
To use the eyedropper, first navigate to the toolbar. You'll find the eyedropper icon there, which you simply select. Once you click on an element with the eyedropper, the color is sampled and selected. You can do this directly in a square or on any other element. Just click in the square, and the color selection will automatically update for you.

By double-clicking on the color box that appears at the bottom, you open the color palette. Here you have the option to adjust the hue to your liking. You can either change it using the color sliders or simply use the presets of the color gradient.

Another useful feature of the eyedropper is that it can sample not only colors but also complete color gradients. If you've created a gradient and want to save it, simply click on it with the eyedropper. This will select not only the main hue but the entire gradient. You can then name and save it using the "New Swatch" function.

Once you've saved your gradient, it will be stored in the swatches, and you can reuse it at any time. This is particularly useful as it helps you maintain a consistent color scheme in your designs.

Another application of the eyedropper is working with images. If you have an image from which you want to sample a specific color, just hover the eyedropper over the desired spot. Hold down the mouse button and observe the live color selection. Choose a hue you like and create a new swatch here as well.
This way, you can generate great colors for your designs with minimal effort, without having to mix them manually. This makes your work easier and ensures a harmonious color concept.
The Measuring Tool in Action
Below the eyedropper is the measuring tool. This is especially helpful when you need precise measurements for your design elements. To use the measuring tool, click in the workspace and draw a line from one point to another. The length of the line and the angle will be displayed in real-time.
For example, you can find out the length of the diagonal of a rectangle. As you draw, the exact length and angle of the line will be displayed – a practical feature to ensure your elements are correctly dimensioned.

If you need another measurement, simply place a new point and draw the line again. The measuring tool automatically updates the results, so you can always keep track even with more complex designs.
Measuring your elements is particularly advantageous when you need to work very accurately. Whether you're working on a technical design or a creative project, the measuring tool provides you with the necessary data to optimize your design.

Summary – Efficient Use of Eyedropper & Measuring Tool in Illustrator
By effectively working with the eyedropper and measuring tool, you can optimize and make your designs in Illustrator more precise. While the eyedropper simplifies color selection and storage, the measuring tool helps you capture dimensions accurately. Use these tools to improve the workflow in your projects.
