Our premium service is called Duolingo Plus, which has its own specific logotype. The colorways of the Plus brand change dramatically to show our learners that they are experiencing an enhanced version of the app.
In the interest of legibility and consistency, ensure the placement and relationship of logo elements remains intact.
The space between the Duolingo logotype and the Plus token is the same width as the counter of the "o" in "Duolingo." That same shape can be used to calculate the padding inside the Plus token, the top alignment of each element, and the baseline of all characters.
To allow the logotype to stand out, do not place any objects such as graphics or text in the clear space shown.
Some Duolingo products and services are uniquely branded, like Duolingo Plus. For sub-brands and initiatives that do not have their own rules, a generic layout exists to help keep our brand family consistent.
The core wordmark and sub-brand title share an x-height and are separated by a space equal in width to the counter of the "o" character in "duolingo." Since the two elements are essentially the same size, we rely on weight to define hierarchy.
In instances where the audience may not be familiar with Duolingo, but where it's necessary to represent a particular sub-brand or team, an alternate lockup may be used that places a greater emphasis of the core branding.
