Digital Signage

The digital signs in the lobby of the Allan Rosenfield Building (722 W.168th St.) are easy to create and a great way to publicize Mailman School, CUMC, and Columbia University events. Below are some basic tips, templates, and guidelines for these electronic posters.

Is my event suitable for posting?

  • Yes, if it is open to a wide audience and sponsored or co-sponsored by a Mailman School, CUMC, or CU department, center, or office.
  • No, if it is by-invitation-only, a course, or an event at an institution outside Columbia. 

What are the technical specifications for the e-posters?

  • Format: JPEG or PNG
  • Size: 1080 pixels wide x 1398 pixels tall (8.5"x11")
  • Resolution: 72 dpi
  • Orientation: Portrait
  • Color: RGB

An easy-to-use PowerPoint template is available which has been formatted to the exact size and orientation required, with fields for suggested content.

Tips for creating an effective sign

  • Clear, simple designs and text work best.
  • Minimize the use of bold copy to the most basic elements, for example, the title, speaker name and date.
  • Remember the signs rotate every 10 seconds. It is best to keep descriptions short.
  • Include the sponsors and co-sponsors.
  • Avoid thin or diagonal lines which will appear pixilated.

File Submission

Email your JPEG or PPT sign to one of the following:

  • For School-wide audiences: submit all files and questions to mailman-signage [at]
  • Students or student groups: visit the Digital Signage Guidelines to submit all files and questions. 

Signs are updated on Tuesdays and Thursdays.

For Tuesday updates submissions should be made by 2pm on Friday and for Thursday updates submissions should be made by 2pm on Tuesday.
