What Is TypeTrials and How Do You Use It to Test Variable Fonts?

Updated

TypeTrials is a browser-based tool for testing variable fonts, built by Pangram Pangram Foundry. You use it to load a variable font and preview how its axes behave before committing the font to a design or build. It requires JavaScript: with JavaScript disabled, the page only shows a notice asking you to enable it, so there is no usable fallback. It is a testing environment, not a font download or licensing service.

What TypeTrials is for

Variable fonts pack multiple styles into one file by exposing design axes—weight, width, slant, optical size, and so on—that you can adjust continuously rather than picking from fixed weights. That flexibility is hard to judge from a specimen image. TypeTrials exists to let you interact with those axes directly in the browser and see the result as you change them.

Its stated scope is "testing variable fonts and much more," and it is powered by Pangram Pangram Foundry, a type foundry. The practical use case is straightforward: you have a variable font file (the site's keywords reference TTF) and you want to see how it responds across its range before you use it.

Basic workflow

The site's public page does not expose a step-by-step interface description, so the workflow below reflects the general pattern for browser-based variable font testers. Treat the specific controls as things to confirm once the page loads.

  1. Enable JavaScript. Open typetrials.com in a browser with JavaScript on. If it is off, you will only see the enable-JavaScript message and nothing else.
  2. Load a font. Expect an option to bring in a variable font file, typically a TTF, or to pick from fonts the tool makes available. Confirm which path the interface offers.
  3. Adjust the axes. Once a font is loaded, look for sliders or numeric inputs for each axis the font supports. Move them and watch the preview update.
  4. Compare and record. Note the axis values that work for your use case so you can reproduce them in your design tool or CSS.

Verification: the preview should change as you move each control, and the axis list should match the axes declared in the font file. If an axis does nothing, the font may not actually include it.

What to watch for

  • JavaScript is mandatory. There is no static preview or no-JS mode, so test on a normal desktop browser rather than a restricted environment.
  • Axis availability varies by font. A variable font only exposes the axes its designer built in. A tester can show controls, but it cannot add range a font does not have.
  • Testing is not licensing. TypeTrials is described as a testing tool. Checking how a font behaves there does not grant rights to use or distribute it; confirm licensing with the foundry separately.
  • Pricing and access are not stated on the public page. Do not assume the tool is free or requires no account—check the site itself once JavaScript is enabled.

When to use it

Use TypeTrials when you are evaluating a variable font and need to feel out its axes interactively—for example, deciding which weight range suits a heading system, or checking whether a font's width axis is usable at small sizes. If you only need a static specimen or a font file to install, this is the wrong tool; go to the foundry or your design software instead.
