Disability and Printing: From Braille to Accessible Signage

Standard print has always excluded some readers by default. The history of disability and printing is really the history of people fixing that — and the fix, then and now, comes down to genuinely simple, deliberate design choices.

Louis Braille and the Six-Dot System

Louis Braille began developing his six-dot tactile reading system in 1821, while a student at the Royal Institution for Blind Youth in Paris, building on an earlier raised-point writing system devised by Charles Barbier. RNIB, founded in 1868, published its first Braille book in 1871 and today holds a Braille library of over 25,000 titles. Around 7% of people registered blind or partially sighted use Braille, with an estimated 20,000 Braille readers in the UK.

Beyond Braille: Legible Print for Everyone

Braille solves reading for a specific group of readers. A much larger, everyday accessibility problem is simpler: print that's too small, too low-contrast, or too cluttered for a great many people to read comfortably, whether or not they're registered as visually impaired. RNIB's Clear Print guidance addresses exactly this — a minimum of 12pt type, ideally 14pt or larger, in a clear font with strong contrast between text and background.

Accessible Print Is a Design Choice, Not an Afterthought

The genuinely useful lesson from over two centuries of accessible print is that it works best when built in from the start, not bolted on afterwards. A sign designed with proper contrast and legible type from the outset costs the same to print as one that isn't — the only difference is whether someone thought about it before the file was sent to press.

Where This Shows Up in What We Print

We already build RNIB Clear Print guidance and BS8300 accessible signage standards into our large format & signage work — character size, contrast and spacing for shopfronts, receptions and exhibition stands with public footfall. If accessibility matters for your signage or stationery, tell us when you send your artwork and we'll flag anything that needs adjusting before it prints.

Frequently asked questions

Who invented Braille?

Louis Braille, who began developing his six-dot tactile reading system in 1821 at the Royal Institution for Blind Youth in Paris.

How many people use Braille in the UK?

Around 7% of people registered blind or partially sighted use Braille, an estimated 20,000 readers in total, according to RNIB.

What is RNIB Clear Print guidance?

A recommendation of a minimum 12pt type, ideally 14pt or larger, in a clear font such as Arial, with strong contrast between text and background — aimed at making everyday print legible for the widest possible audience, not just registered Braille readers.

Before Braille: Raised Letters and Their Limits

Braille did not appear in a vacuum. Charles Barbier, a French army officer, had devised a raised-dot code known as night writing, which Louis Braille encountered in 1821. Barbier's system worked, but it was cumbersome to read with a fingertip. Braille, who had been blind since early childhood after an accident in his father's workshop, simplified the idea into the compact cell he first described in print in 1829. He died in 1852, and the school where he had studied and taught adopted the system two years later. Wider adoption followed an international conference in 1873, which is why Braille became the common tactile code across Europe within a generation.

Moon Type: A Different Answer to the Same Problem

A second tactile system grew up in Britain. William Moon, a blind teacher from Brighton, formulated his ideas in 1843 and published his scheme in 1845. Instead of dots, Moon uses raised lines, curves and angles, and many characters resemble the shapes of printed letters. That is why it has been valued by people who lose their sight later in life, or whose fingertips are less sensitive, and who find a dot code hard to learn. It is far less widely used than Braille, but it is a useful reminder that no single format suits every reader.

The Legal Idea That Changed the Question

For most of print history the burden sat with the reader: if you could not read the page, that was your problem. Modern UK law moved the question. The Equality Act 2010 places a duty on service providers to make reasonable adjustments for disabled people, and information in an accessible format is part of that thinking. In the NHS the Accessible Information Standard, in force since August 2016 and updated in 2025, asks organisations that provide NHS care or adult social care to meet people's information and communication needs. The duty falls on the organisation, not the individual, which is why accessible print is now a planning decision rather than a favour.

Clear Print: What the Guidance Actually Says

General accessible-print guidance is consistent across the organisations that publish it. The points below come from widely used clear print advice, and they apply to leaflets, forms, menus and signs alike:

• A minimum of 12pt for body text, ideally 14pt, applied to everything including page numbers, captions and footers.
• Plain sans serif typefaces such as Arial or Verdana, without decorative or handwriting styles, and no very light weights.
• Strong contrast between text and background. Reversed-out text, such as white on black, is best kept to headings and short blocks.
• Left-aligned text with ragged right edges rather than justified text, and no hyphenation at line ends.
• More than single line spacing, generous margins and clear space between paragraphs.
• Do not rely on colour alone to carry meaning, and avoid placing text over a busy image.
• Use bold, capitals and italics sparingly. Avoid underlining.
• Headings noticeably larger than body text, in a logical order.

Large print is a different thing from clear print. The accepted starting point is 16pt Arial or bigger, and requests for large print are most commonly for 18pt to 20pt. If you are producing large print on request, ask the reader what they need rather than guessing.

Where Printed Clothing Comes In

Accessible design is not only about paper. Printed clothing and signage can help, and it can also get in the way, so the same habits apply:

• On an event T-shirt or a staff top, a large, plain name or role in high contrast is easier to read from a distance than a decorative script.
• A printed role such as "Steward" or "Help" on the back of a volunteer top helps everyone find assistance, including people who rely on following clear cues.
• Assistance and support-group tops can carry a short, simple message in a legible face rather than a long paragraph.
• Avoid placing text across a busy graphic. The contrast problem applies on cotton as much as on paper.
• Think about the garment colour. A dark ink on a pale garment, or the reverse, is easier to read than mid-tone on mid-tone.

When we proof an order, the proof is the moment to check readability, so look at it at the size it will really be seen, not zoomed in on a screen.

Practical Steps for Your Own Print

1. Decide who will read it, and in what light and from what distance, before choosing a size.

2. Set the text size from the guidance above, and test it by printing the file at actual size on an ordinary printer.

3. Check contrast honestly. A pale grey on white that looks elegant on a laptop can be unreadable in a bright reception area.

4. Keep the wording short and put the most important information first.

5. Offer an alternative route for people who need one, such as a phone number or an email address for large print or other formats.

6. Share your artwork and your intended use when you request a quote, so potential problems are spotted at the proof stage. Our artwork and file preparation guide explains how to send a file that is ready to print, and our large format and signage page covers signs, banners and displays.

Questions About Accessible Print

Is Braille the same as large print?

No. Braille is a tactile code made of raised dots. Large print is ordinary text set at a bigger size, and it helps readers who have some usable sight.

Does accessible print have to look dull?

No. Contrast, size and spacing are choices that sit alongside colour and brand, and many well-designed leaflets meet clear print advice without losing their identity.

Who decides what format a person needs?

The reader does. The most helpful organisations ask, record the answer and then supply information in that format each time. Our flyers and stationery guide is useful for the practical side of getting leaflets and cards ready.
