Identity

Logos

How we write our name, how we use our symbols — these are the closest we get to a "signature" for Duolingo. How they appear, whether tiny on a screen or enormous at an airport, becomes a crucial way for our customers and partners to find and trust us.

Our typographic signature uses custom letterforms inspired by the curves and shapes of our famous mascot, Duo. Look closely and you'll see that the flick on the "g" mirrors Duo's expressive eyebrows.

The logotype can be used in one of three colors: feather green, white, or gray.

Logotype

Clear space

To allow our logotype to stand out, do not place any objects such as graphics or text in the clear space shown.

Logotype

Minimum sizes

100 px
Screen
35 mm
1.375 in
Print

The logotype should always be legible. Never use it at sizes smaller than specified.

Logotype

General positioning

This general guidance applies to digital or print applications, including both portrait and landscape orientations.

When creating a composition, place the logo in one of the four corners, or center it on the central vertical axis. Take advantage of the space and make the logo as large as possible. Remember: Be bold, be proud, make it big!

Avoid using the logotype at sizes smaller than one-third of the canvas width.

Logotype

Rotation

Horizontal
Vertical

Typically, we place our logotype flat on a 0° angle. Horizontal is our default rotation state. Examples include use in our app, on our website, and most advertising formats.

Occasionally, we rotate our logotype 90° to make the best use of space with unusual formats. By rotating the logo vertically, we are able to display it at a larger scale. Examples include vertical ad spaces such as "skyscraper" banner ads, physical banners/flags, and playful applications like merchandise or stationery.

Landscape Lockupanchor

download

Displaying Duo next to our logotype is useful in third party applications, where Duo's recognizability would aid in brand awareness. This fixed lockup ensures that they will safely coexist in such instances.

Supply this logo lockup in a press release, at conferences, or for use in spaces managed by other companies.

Landscape Lockup

Clear space

The bottom of Duo's body is aligned with the inside of the loop on the "g" character. The side of his head aligns with the top of the "l". A space equal to one-half the x-height is left between Duo and the logotype.

Do not place any objects such as graphics or text in the clear space shown.

Landscape Lockup

Please don't...

  • Change the scale or position of Duo in the lockup.
  • Allow Duo to touch or sit on the logotype.
  • Use alternative Duo poses in a lockup.

Portrait lockupanchor

download

The stacked version of our logo is useful in third party applications. Because Duo is extremely recognizable, his larger size and more prominent placement helps us stand out among other apps and brands. Use this version when supplying logos to third parties, and when the usage is within a square or tall space.

To allow our logotype to stand out, do not place any objects such as graphics or text in the clear space shown.


Iconanchor

download

Because Duolingo's presence largely exists online, the consistent appearance of our icon is critical in ensuring our audience recognizes our brand across various spaces. In many cases, this symbol is the first introduction that people have to Duolingo.

Icon

Avatars

Our icon is our face on social accounts, keeping Duo's personality front and center. It can be safely used at a wide variety of sizes, as small as 16px like our favicon.

In instances where we know the avatar will be displayed as a square (with or without rounded corners), Duo's eye mask should touch the left and right edges of the frame. When the masking shape approaches a circle, there should be space between the eye mask and the edge on either side.

successAll good.
