Why test fonts?

Testing fonts is an important step in the design process. It ensures the optimal selection and implementation of typefaces. Let’s explain wider why testing fonts is necessary:

Tools to provide font testing

When testing fonts, different types of tools can be helpful for evaluating their visual appeal, readability, and compatibility. You may need only one of them or a few, depending on the project requirements, and a test plan. Here are some of them that you may find useful for such a purpose:

Type of toolRepresentativesFunctionality
Graphic design softwareAdobe Photoshop, Adobe Illustrator, Affinity DesignerThese software programs allow you to easily create designs and mockups that incorporate different fonts. They let you visualize how fonts will look within your design compositions.
Word processing softwareMicrosoft Word, Google Docs, Apple PagesAllow you to input and format text using different fonts, sizes, styles, and spacing and provide you with a quick way to assess readability and legibility in heavy texts.
Web design and development toolsAdobe Dreamweaver, Visual Studio Code, Sublime TextOffer live preview capabilities, so you can see how fonts look on web pages in real-time.
Browser developer toolsGoogle Chrome’s DevToolsLet you inspect and experiment with fonts directly within the browser
Online font libraries and resourcesGoogle Fonts, Adobe Fonts (formerly Typekit), Font SquirrelOffer extensive collections of free and paid fonts. These platforms provide browsing and testing capabilities, so you would be able to preview and compare fonts within various sample texts.
Font testing and comparison toolsFontBase, RightFont, FontExplorer XProvide features such as font preview, filtering, searching, and side-by-side comparisons. Have functionality of comparing and evaluating multiple fonts simultaneously.
Online prototyping and mockup toolsFigma, Sketch, Adobe XDAllow you to create interactive prototypes or realistic mockups that showcase fonts in the context of user interfaces or visual design elements. These tools offer the ability to apply fonts to various elements, simulate different device screens, and collect feedback.
Tools to check accessibilityColor Contrast CheckerThe app follows Web Content Accessibility Guidelines (WCAG) to make web content more accessible by finding optimal color contrast for the user interface elements.

How to test Google fonts?

Testing Google Fonts is a simple process that allows you to preview and assess the suitability of different typefaces within your projects. Here’s a brief instruction:

  1. Visit the Google Fonts website where you can browse through the collection by category, and popularity, or use the search bar to find specific fonts.
  2. Find a font you want to test and click on it to access its dedicated page. There, you’ll see its overview, including sample text showing the font’s appearance and various available styles and weights.
  3. To test the font with your own text, just enter the desired sample text in the text input box instead of the default sample.
  4. If needed adjust the font size, change the background color, or apply different formatting options like bold, italic, or underline. These options allow you to simulate how the font will look in different contexts and styles.
  5. Compare multiple fonts side by side, if needed. For this select the “Add to Collection” button on each font page. Once you have added several fonts to your collection, click on the “Collection” button at the top right of the website. Now you can view and compare the selected fonts simultaneously.
  6. When you find a font that suits your needs, you can download it by clicking the “Download” button. Choose one of the provided download options, including downloading the font files or getting the CSS code to integrate the font into your website.

Following these steps, you can thoroughly test and evaluate different typefaces within Google Fonts. You can make informed decisions about font selection, regarding visual appeal, readability, and suitability for your specific design or web project.
