If you are working to make sure a building is accessible to people with additional needs, there are a number of things you will need to consider. Alongside wheelchair ramps and lifts, you will also need to install braille signage so those who need assistance with their sight can easily navigate the space. There are certain requirements which need to be met to ensure that braille signage meets the current requirements. Read on to find out more about installing braille tactile signs in your building complex.
When you are designing signage for the rest of your building, you will expect to look through the many different fonts which are available until you find the perfect fit. However, when it comes to designing braille signage, only one font will do. Australian law states that braille characters should be produced using standard Arial font, without the use of script, italicisation or decoration. The reason for this is very simple. Arial is a very clear font which is evenly spaced when typed. These features make it easier to read using touch alone when compared to other typefaces. Due to the differences between fonts, the use of another typeface could confuse a person who is expecting to run their hands over a message produced using Arial.
When designing signage using braille, you must pay attention to the spacing between each character. If characters are too close together, this could cause confusion when a person attempts to read the sign as each individual letter will run into the next. The minimum amount space between two separate characters or letters is 2mm. While this distancing can sometimes create signs that look as if they could be compressed for greater aesthetic value, it is important to remember that, unlike visual signs, braille is designed for communication with those who are sight limited and is not based on how pleasing something looks to a sighted person.
When it comes to the size of the characters on your braille sign, you have a little more scope for adjustment. Australian law states that the characters that use braille should be between 15mm and 55mm in height. However, if you plan to use braille on a sign alongside information for a sighted person, the braille should be ay least 20mm
