With ADA signs, it is important to follow certain guidelines so that you are sure that you are compliant with what the law says. If you do not abide with the rules, you are sure that you will attract things like fines and penalties which will cost you a lot of money at the end of the day. Some of the factors that you need to consider when designing ADA signs are briefly highlighted below.
One of the things that you need to consider when it comes to the ADA signs is the font and it is important to remember that there is a specific font that is required. It is important to make sure that you are also keen on things like the case, proportion and height of the letters and remember to use san serif font. To make the sign beautiful, you can play around with things like the shape, color and material of the sign.
It is important that you ensure that you apply kerning to the characters even though it is something that most people do not enjoy but it is a requirement for the ADA sign. It is important to have a distance of 3.2mm between characters since some of them naturally tend to be too close together. With the spacing you may need to have a larger sign since you cannot squeeze everything close together because people with visibility issues may not be able to see the letters when everything is close together.
The character size is also something else that you need to consider when you are designing the sign since there are a few requirements when it comes to the size of the letters. The maximum letter size should be 2″ and the minimum size should be “. Sometimes this rule is broken when the design does not give room for compliant braille or with certain frame systems but the only exception to the rule needs to be when it is a dual message sign and the tactile is allowed to be a minimum of “.
With braille signs, there is a certain code that needs to be followed as well. There is no rule about excluding or including any braille material but it is important to follow shape as well as size of the braille dot cells. Ideally grade II braille is what is required in most cases since it has 189 contractions and uses short form words.
With placement of the signs, you need to consider flooring as you determine placement of the signs since there is specific requirement when it comes to signage mounting. Make sure that you confirm with the building inspector if you are unsure about the height where you need to mount the signs. Make sure that you interpret the codes well so that you are able to get the right height.
