  • Only School, CUIMC, or CU events or news are posted to the digital screens or in designated spaces in elevators.
  • Each announcement will appear on the digital screen for 15 seconds. The School reserves the right to adjust the appearance time based on the number of announcements in the rotation.
  • Posters on easels are not permitted in the lobby.
  • Flyers taped to the walls are not permitted in the lobby or elevators.
  • Please refer to the School as "Columbia University Mailman School of Public Health or "Columbia Mailman," but never MSPH. The School reserves the right to make decisions about when a posting will appear in the announcement rotation.

When the digital signs are active, please follow these guidelines:

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

Is my non-event announcement suitable for posting?

  • Yes, if it is a Non-Degree or Special Program listed on the Columbia Mailman Academics website
  • Yes, if it is an announcement about funding opportunities open to Columbia Mailman faculty, staff, or students.
  • Yes, if it is an announcement regarding the Allan Rosenfield Building facilities and opperations.

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.
