3. Here is the same passage but with the top
halves of lower case letters. Is it easier for you
to understand?
Note that the shapes of the lower-case letter are more
informative. This has been used as an argument for why
lower case is easier to read.

4. Evidence
A study using 40 readers found that when all
letters were capitalized in long text, reading
speed was 10% slower than when lower-case
letters were used (See Persuasive Advertising p 261).

results of your application.
• For example, identify situations where readability is an issue
and avoid uppercase.
