| Guidelines for
Designing Clear Text |
|
There are some rules to follow to make reading
easier. Reading can be difficult if a person has a visual impairment because:
- The middle part of the retina is damaged.
- There is less light that enters the eye.
- The retinal image is blurred.
If there is not enough light to see and vision
is blurred it is difficult to see the contrast in writing. If the central
retina is damaged it is difficult to see small print. |
|
There are guides that you can follow that will
make reading clearer for people who are visually impaired. |
|
Always make the text bold. Sometimes light
letters on a dark background are easier to read than dark letters on a light
background. |
|
It is better to only use colour for titles and
headlines as it will be easier to see text in black and white. |
Font size should be size 16 to 20.
Between lines of text make the spacing at least 25
percent of the point size. This makes it easier to find the beginning of the
next line.
Using upper and lower cases is easier to read than
using Italics or keeping all the letters the same size. It is best to use Arial
font.
|
Avoid complicated, decorative fonts. Arial type
fonts, with familiar, easily recognisable characters are best. Bold versions of
any typeface are often more legible, since the letters are thicker. |
|
Keep spacing wide between letters. Fonts that
have the same spacing are clearer to read. |
|
Some people with partial sight have problems
with glare. Do not use glossy paper, as it is not easy to read from. Black
print on a yellow background provides an excellent contrast but light blue
print on a grey background is very difficult to read. |
|
It can be helpful to use different colours and
sizes on the cover of a book or document to make it easier for the person that
is visually impaired to find. |
