The Caltech Logo

Our logo was developed to help increase awareness of and appreciation for Caltech. It confidently reflects the Institute's stature and reputation by emphasizing the Caltech name. The logo should be used to represent Caltech in all communications except the most formal, for which the seal is reserved.

  • Treat the logo as artwork, not as typography. It should never be re-created or typeset.
  • Do not manipulate the logo. This includes but is not restricted to substituting or changing the logo color or font, applying shadows, outlines, or surrounding boxes, and using the logo as a window for imagery. Use only approved artwork in communications.

Please observe the following guidelines when using Caltech's logo:

Please Note: the .png format is best for web projects, and .jpg or .eps are preferred for print projects.

Acceptable Colors

The primary color option for the logo is Caltech orange (Pantone 165, HEX #FF6E1E).

Positive reproductions of the logo may also appear in black; reverse reproductions should appear in white.

The orange logo should be used on lighter backgrounds and images to maintain legibility. This includes backgrounds that are white, less than 20 percent black, or more than 80 percent black.


The black and white versions of the logo may be used on any color background or image with adequate contrast.

Clear Space

Logo Clear Space

The Caltech logo must be surrounded by a clear space at least equal to the height of "e" in the logo. The clear space is measured from the top, right, left, and bottom of the logo.

No other design elements may be positioned within this space, including typography, photography, or illustration. As a general rule, more clear space is preferred.

Minimum Sizes

Logo Minimum Sizes

To preserve the integrity of our identity, reproductions below a recommended size are not permitted as they compromise readability.

  • The preferred logo size on 8½" x 11" print applications is 1.25".
  • The minimum allowable print reproductions for all of our logos is .75" width, with the width measured from the left edge to the right edge of the logo.
  • When using the logos online, or for any other digital media, please do not size the mark down less than 70 pixels wide.

Hierarchy and consistent placement of the Caltech logo in a print layout is critical to maintaining our visual system, and for building recognition for the Institute without distracting from your message.
