Our door signs come in a range of colours and options. They have all been designed to be clear and easy to read. Research has shown that text should be in upper and lower case - not capitals letters. This makes them easier to read - not only if you are a dementia patient, but also if you have had a stroke, or if you have dyslexia. Along with this black text on a yellow background stands out best. The signs should be placed at a fairly low level. We recommend 1.2 - 1.5m high.
