ADA Braille Signs

Different kinds of ADA signs follow different sets of rules. When it comes to ADA Braille signs, some of the rules you need to adhere to include rules made for the proper creation of the Braille translations on these signs, as well as the proper placement of these translations on the sign itself. You will also need to follow the guidelines set for proper translation from text to Grade II Braille, and the right spacing of these translations from the text up top as well as between each other.

When you make ADA Braille signs, you need to keep in mind that the rules set for the proper creation of such signage is to ensure that you not only avoid non-compliance issues but also give people with visual impairments the kinds of signs they can effectively use. These signs need to be easy for them to read with the use of their fingertips, hence the need for the Braille translations on these to be not only accurately translated but also properly crafted for easy reading. How do you craft Braille signs that are ideal for use by those who really need them? Here are some of the rules that you should follow.

ADA Braille Signs Rules for Creation

Braille translations on your signs need to be in Grade II or contracted style – signs need to carry Grade II Braille because of the fact that these are easier to read than Grade I Braille which can mean longer translations due to the need to use one set of dots per letter in the text. With Grade II Braille, your translations will be shorter since the dots used are either commonly used words that are contracted into one set of dots, or syllables and pairs of letters contracted into one set of dots as well and used to create whole words.

These Braille dots need to be domed and rounded to be easy to read - these dots need to follow very specific guidelines as well in terms of shape and how they feel to a person’s fingertips. In the past, Braille translations were not made in the rounded, smooth shape that they are in today and were, in fact, somewhat square-ish due to the lack of equipment back then that could create these smooth, round bumps you see on signs today. These Braille dots that you see on ADA Braille signs made recently are either made the Raster way or via modern engraving machines that have the capability to copy carefully designed sign designs plotted via a computer.

Proper spacing of dots within individual characters as well as between each character is needed – if proper spacing is not followed, you will find people being confused about what these signs say when they read these with their fingertips. The spaces between dots in one character should be between 2.3mm and 2.5mm. For the spaces between the dots of one character and the next one, a measurement of 6.1mm and 7.6mm between dots is what is needed. If there are still translations for the sign text on a second line, the distance between the bottom dots of the top character and the top dots of the bottom character should be somewhere between 10mm to 12mm.

The right dot measurements should be followed – as with the spacing of these dots, ADA Braille signs should carry dots that are made in the right measurements that the ADA has mandated. For the base diameter of these dots, a measurement of 1.5mm to 1.6mm is needed for this to be compliant. For the height of these dots, these need to be somewhere between .6mm and .9mm above the sign’s background.
