Beautiful Signs for a Better Planet

Room Sign Installation Guide


This guide makes Green Dot Sign’s easy to install. We offer eco-friendly wood peg and foam tape options. There is no sign price difference based on the method of installation, simply choose what works best for your walls and team.

Room sign installation methods are described in easy to understand language and photos below.  While many handymen or construction crews are more then capable of installing signs, there’s a lot of value in using a professional sign installation company.  If you prefer to hire a local professional feel free to work through us by calling or filling out our Contact Us form.  If you want to contract with a sign installer directly, we recommend starting with the Professional Decal Application Alliance (PDAA) or 3M certified installers database to find professionals in your area.

Room Sign Installation Instructions

Your sign will arrive prepared to be installed based on the 4-peg or sign grade foam tape selection you make while ordering.

All Green Dot signs ship with instructions and templates like those below. They are included here for informational purposes, no need to print them out in preparation for your project.


The Americans with Disabilities Act (ADA) specifies where room and space identification signs must be wall mounted relative to entry door latches. Before mounting an ADA-compliant sign, it is worthwhile to confirm placement with your local building inspector.

We’ve included room sign installation height and location requirements here, but for more information on ADA sign requirements please see our ADA Overview.

The ADA specifies that wall signs must be mounted so that the bottom line of tactile characters is at least 48 inches high and the top line is at most 60 inches high. This measurement is taken from the base of the letters (except in CA where it is measured from the bottom of the braille).

Wall mounted signs must be centered in the 18 inch horizontal space immediately next to the door. When there is not enough wall space, use the nearest adjacent wall.

Most room signs are to be mounted on the latch side of the door. However, there are a few exceptions:

  • On double doors that are both active, mount sign on the right side
  • On double doors with one active door, mount sign on the inactive door
  • On outward swinging doors, mount sign on the side outside of the door arc swing (i.e. if the door were open all way then the wall that would still be visible is the wall to use)

In rare cases signs can be door mounted. On inward swinging doors, a sign may be mounted on the door if all three below criteria are met:

  1. The door closes automatically
  2. Door does not have a hold-open device
  3. Sign is mounted on the push side of the door
