Embossed Braille signage represents a critical element in creating barrier-free environments across the European Union, the Broadband Technology Association stated.
Legal basis and scope of application
The international standard ISO 17049:2013 defines the UN Convention on the Rights of Persons with Disabilities requires public buildings to provide “signage in Braille and in easy-to-read and understand forms.”
According to the company, the key legislation included:
- European Accessibility Act (EAA) 2019/882 takes effect from 28 June 2025
- Web Accessibility Directive 2016/2102 requires public sector accessibility
The harmonised European norm EN 301 549 v3.2.1 (2021-03) provides uniform accessibility criteria across all EU member states.
Technical requirements standards
ISO 17049:2013 defines core requirements for braille signage, while EN 17210:2021 outlines accessibility criteria for built environments.
Technical parameters
- Dot dimensional accuracy – ISO 17049:2013 specifies the dot base diameter of 1.5-1.6 mm with center-to-center spacing tolerances
- Durability requirements – Materials must maintain tactile integrity under normal use conditions with a domed or rounded dot shape for extended service life
- Material contrast requirements – Minimum 70% visual contrast for low vision users, while tactile distinction relies on raised dot height (minimum 0.8mm above background) and proper dome shape
Placement rules
General principles
EN 17210:2021 requires positioning signage at 1.2-1.6 meter elevation, with 1.4 meters recommended.
Sequence of placement of elements:
- Information sign – 20 cm from the door frame;
- Pictograms – 10 cm from the sign;
- Call buttons – within reach.
Mandatory requirements
EU requirements apply uniformly across all public buildings regardless of sector:
- All facilities – Room identification signs, restroom signage, exit routes, accessible entrance markers
- Medical facilities – Room numbering, restroom identification, emergency exit marking
- Educational institutions – Classroom numbers, office identification, accessible routes
- Retail outlets – Room identification, restroom signs and accessible features
Types of tactile signage
A modern navigation system for people with visual impairments includes several types of tactile signs:
- Signs at the entrance with the name of the organisation and opening hours
- Signs on offices indicating the purpose of the premises
- Tactile diagrams with floor plans and evacuation routes
- Warning pictograms with a minimum 6-inch height field, accompanied by descriptive text
- Directional signs to important facilities
All signage types must adhere to EN 301 549 specifications.
Practical recommendations for implementation
To ensure compliance with legal requirements, it is recommended to:
- Conduct an audit of the existing navigation and identify missing elements of the information system
- Create a comprehensive layout plan that takes into account the institution’s specific requirements and visitor traffic patterns
- Select a certified supplier that guarantees compliance with EN 301 549 and ISO 17049:2013
Specialised companies, such as Bsign Store, offer professional custom braille signs with high-quality tactile fonts that can be adapted for various accessibility requirements.
Train staff to work with visitors with visual impairments.
