What is the minimum thickness of public restroom signage?

The minimum thickness of public restroom signage is specified as 7.5 mm to ensure visibility, durability, and accessibility. This thickness allows the signs to be easily processed and recognized by individuals, including those with visual impairments. Signs that are too thin might not be adequately durable for public spaces where they are frequently touched or exposed to environmental elements. Utilizing a thickness of 7.5 mm strikes a balance between being robust enough to withstand wear and tear while still being lightweight for easy installation. This standard reflects best practices in signage design for public restrooms, which aim to ensure that all users can quickly and clearly identify these facilities.
