At Montgomery Engravers, we know that accessible signage is a vital visual bridge. It gives essential safety and location information to everyone, especially those with low vision, colour blindness, or mobility impairments.
From high-contrast text and specific colours to universally recognised symbols, these signs are the essential guides that allow people to navigate the environment with independence and dignity.
Our guide will explain the easy-to-follow rules, legal requirements, and design precision needed to create truly effective and visually accessible signage, ensuring your premises meet UK legal standards and, most importantly, the needs of all your visitors and staff.
The Legal Requirements for Clear Signs
In the UK, the need for accessible signs is covered by the Equality Act 2010. This law requires organisations to make reasonable adjustments to ensure that disabled people are not put at a disadvantage.
In terms of physical buildings, the rules are detailed in the UK Building Regulations, specifically in Approved Document M. This document requires that key location signs and signs for accessible features must be visual and designed with careful attention to height, font size, and, critically, visual contrast between the text and the sign’s background.
Simply put, a confusing or hard-to-read sign is a barrier. We follow expert design standards to make sure your signs are instantly understood and easy to see in any light.
Rule 1: The Power of Contrast and Colour
The most important factor in designing a clear sign is visual contrast. For people with low vision or who have difficulty distinguishing colours, a sign must offer maximum clarity.
The Contrast Rule of Thumb
Contrast is measured by the difference in how much light the sign's background reflects compared to its text. To be easily readable by most people, a sign must follow a simple principle: The text must be significantly darker than the background, or the background must be significantly darker than the text.
Easy Contrast Check: Design guidelines specify that there must be a strong difference between the text colour and the background colour. Think of high contrast combinations like black text on a pure white sign or white text on a deep blue sign.
What to Avoid: Combinations like grey on light blue or yellow on white are confusing and fail to provide the clarity needed for people with low vision. We check the exact brightness of every colour used to ensure this required contrast level is met.
The Non-Glare Finish
A perfect colour combination can be ruined by reflection. Shiny surfaces, like polished metal or high-gloss plastics, can create glare that washes out the text, making the sign impossible to read under bright lights.
Requirement: All accessible signs must have a matte, non-glare finish. This ensures the information can be read clearly from any angle and in any lighting condition.
Material Focus: At Montgomery Engravers, we only use materials - such as specific acrylics or anodised metals - that provide this essential matte, non-reflective surface.
Rule 2: Visual Communication and the ISA Symbol
Signs that point to accessible features must use the universally recognised symbols.
The International Symbol of Access (ISA)
The International Symbol of Access (ISA), commonly known as the wheelchair symbol, is critical.
Universal Meaning: The ISA is recognised globally and immediately tells a person that a feature - like a parking bay, a ramped entrance, or an accessible restroom - has been designed to accommodate people with mobility needs.
Clear Use: This symbol must be used clearly on the sign to indicate the accessible feature. For example, the symbol should appear next to the words "Accessible Lift" or "Accessible Changing Room."
Colouring: The symbol itself must stand out using high contrast. The standard white symbol on a blue background is often used because it provides excellent contrast and is easily identifiable.
Rule 3: Simple, Clear Design
Beyond colour, the actual look and layout of the sign must support quick understanding.
Typeface and Text Style
Font Choice: Use only simple, plain, clear sans-serif fonts (like Arial or similar styles). Highly decorative, thin, or unusual fonts reduce reading speed and cause confusion.
Mixed Case: Text should be set in mixed case (using capital letters only at the start of sentences or proper nouns). Using ALL CAPS makes words appear blocky and harder to recognise quickly than standard sentence formatting.
Size and Spacing: The size of the letters must be large enough for the intended viewing distance, and there must be plenty of clear space around the text to avoid a crowded or messy look.
Rule 4: Consistent Placement and Wayfinding
Even a perfect sign fails if it is placed in the wrong spot. This is where accessible wayfinding comes in.
Wayfinding is simply the entire system that helps people figure out where they are and how to reach their destination without confusion. Good wayfinding is about creating a logical, reliable path using consistent signs, which is vital for everyone to move through your space independently.
Consistency is Key: Signs should be placed consistently throughout your facility - at the same height and in the same logical location (e.g., always next to the door handle). This predictability helps users gain confidence and navigate without confusion.
Mounting Height: For the best visual clarity, signs are typically mounted at eye level, around 1.4 to 1.6 metres above the floor. This height ensures visibility for everyone, whether standing or seated.
Easy Language: The text on the sign must be short, direct, and focused on the destination or service. Always use positive, helpful language (e.g., "Ramped Entrance" is preferred over "Disabled Entrance").
It’s also important to note the need for accessibility in temporary settings, not just permanent buildings. For example, when planning an outdoor event, organisers should ensure clear visual paths for mobility aids and high-contrast directional signs are in place.

The Legal Requirements for Clear Signs
In the UK, the core legal requirements for accessible signage are rooted in the Equality Act 2010. This law requires organisations to make reasonable adjustments to ensure that disabled people are not put at a substantial disadvantage.
In terms of physical buildings, the rules are detailed in the UK Building Regulations, specifically in Approved Document M. This document requires that key location signs and signs for accessible features must be visual and designed with careful attention to height, font size, and, critically, visual contrast between the text and the sign’s background.
