size requirements for federal workplace posters
There are only two posters where the regulations specify a size (the OSHA poster and Executive
Order 13496 poster), but all federal workplace posters must be easily readable. The U.S. Department of
Labor (DOL) provides posters in the proper size for free on the DOL Poster Topic page or by calling
the Department at 1-866-4-USA-DOL (1-866-487-2365).
