Much like any other component on your ADA signs, the use of Braille comes with a list of things thatBraille ADA Signs you need to remember. These are rules that you need to follow in order for your sign to be considered compliant with ADA standards. As such, these rules are rather stringent and should be followed accordingly or you will have wasted a perfectly good sign simply because some parts of it, particularly the Braille part, is not up to standard.

Putting Braille dots on your signs is not as easy as it may seem, although sign manufacturers do have machinery and equipment that makes this task rater easy to accomplish. If you want your signs to have the right kind of Braille translations on them, you should find an expert sign specialist to do the job for you. Such sign specialists know the rules that govern the making of signs with Braille on them and how to follow such rules.

Braille Dots – the dots that are used to create the Braille translations of signs need to be “domed”. Domed Braille dots can be achieved by means of a few methods, however, these days, considered the best process for the creation of such dots is the Raster method. This particular Braille dot creating technique uses a Raster drill that raises the sides of the engraved dots on the sign and an imbedded bead that gives the sign’s Braille translation the beaded dots it needs.

Spacing – the spaces in between the Braille dots on your sign are as follows: between two dots in the same letter – 2.3 to 2.5 mm; between two dots for letters that are side by side – 6.1 to 7.6 mm; between dots from letters above and below – 10.0 to 10.1 mm. These dots should also 9.5 mm below the last line of tactile letters found on the sign it is translating.

Dot sizes – the Braille dots on your signs should also follow set size guidelines. For example, the recommended dot base diameter is between 1.5 and 1.6 mm. This means that the bottom part of your Braille letters should be in this size. For the dot’s height, a .6 to .8 raise from the base is required.

Placement – Braille translations should always be found directly beneath the text it is translating. If your sign is multi-lined, the entire Braille translation should then be placed directly under the last line of text on your sign.
