Text in all Upper Case

Test Weight: normal
A text in upper case reduces the reading speed by approx. 10%. The single words of the text are not easily recognised by the eye, and the whole text blurs into a block. A text in upper case is perceived as aggressive, amateurish, childish and unprofessional. Use upper case only for short titles.

Source and further information:
"Prioritizing Web Usability" by Jakob Nielsen/Hoa Loranger.
Compare also with Schriver, Karen in Dynamics in Document Design, page 274:
"When text is set in all capital letters, reading speed is slowed about 13 to 20 percent. Reading speed is optimal when  uppercase and lowercase letters are used. When extra emphasis is needed, bold has been found to be a better cue than uppercase."
An additional tool is available for this test, which allows to highlight any warning, hints and tips in the source text of the website. Click here for the tool: http://www.qualidator.com/Web/en/ProductsServices/SiteAnalyzer2.htm

Spätestens wenn Referenzkunden aufgeführt werden, müssen CI und Name des Kunden eingehalten werden. Viele Großkonzerne besitzen Namen in Großbuchstaben. Denken Sie an Fernsehsehsender, Sportschuhe, Automarken usw. Gewichtung des Tests: normal Für professionelle Webseitenauthoren daher eine "normale" Bewertung unpraktikabel. Die Bewertung greift nur, wenn man die Wahl hat groß oder klein zu schreiben. Alles kl.ein zu schreiben und eine Caps-Klasse einzufügen ist ebenso unfug. Ich schlage, da sie sicher auch professionelle Webseitenauthoren im Auge haben, eine geringe Gewichtung vor.
