All Caps vs Bold

They're intended for emphasis and if everything (i.e.: a whole paragraph) is all caps/bold/italic, nothing is emphasized. Italicization is used for gentle emphasis, bold is used for heavier emphasis. All caps are another alternative means of emphasis. None of these should be used on more than a few words together.

Is it grammatically correct to use all caps?

For this reason, etiquette generally discourages the use of all caps when posting messages online. While all caps can be used as an alternative to rich-text "bolding" for a single word or phrase, to express emphasis, repeated use of all caps can be considered "shouting" or irritating.

What does all caps mean slang?

Dictionary.com credits some early internet message board denizens with setting the modern foundation for what we now collectively understand: Typing in all caps is essentially yelling. And just like yelling in real life, it is sometimes useful, and sometimes just plain rude.

Does all caps reduce reading speed?

“When text is set in all capital letters, reading speed is slowed about 13 to 20 percent (Breland & Breland, 1944). Reading speed is optimal when uppercase and lowercase letters are used (Poulton, 1967; Rickards & August, 1975).

Is Bold text effective?

Bold is used to highlight the text and capture the readers' attention. The bold tag is used for strong emphasis. When you feel like emphasizing something, you need to first consider using the italics, only use bold text if you are not satisfied by the emphasis the italics did to your text.
