Understanding AP Style Numbers
If you want to follow the content writing style used by magazines, newspapers, editors and journalists, then you need to study up on Associated Press style, or AP style. This style of writing is very commonly used in SEO content writing such as business blogging, press releases, eBooks, white papers and more. In the past we discussed how to correctly use AP style title case, and now we’re here to tackle the often confused topic of AP style numbers.
Knowing the Basics of AP Style Numbers
So how do you know when to spell out numbers in AP style? In general, you should spell out all numbers one through nine and use figures only for numbers 10 and above. While this rule seems short and sweet, there are a lot of exceptions that you need to be aware of.
AP Style Numbers Examples:
– My pet monster has three heads and five eyes.
– Did you know that 10 out of 25 people believe phony statistics?
Beginning a Sentence With a Number
When starting a sentence with a number, you usually want to spell the number out. However, there is an exception to this exception (things can never be easy, right?). If you start a sentence with a year, then use the figure.
Introductory AP Style Numbers Examples:
– Four thousand people gathered to celebrate the boy band’s upcoming album.
– 1999 was a good year to party, according to Prince.
AP Style Addresses
Always use figures for numbered addresses. However, if the name of the street is a number, then you should default back to the basics: spell out First through Ninth, and use figures for 10th and anything higher.
AP Style Address Examples:
– The President of the United States lives at 1600 Pennsylvania Avenue.
– The Empire State Building is located at 350 Fifth Avenue in New York.
AP Style Ages
Use figures when writing ages:
AP Style Ages Examples:
– My 5-year-old brother is stinky and needs to bathe.
– The actress, 7, is being managed by her mother, 42.
AP Style Dates
Use figures when discussing dates, but never turn to ordinal numbers. In other words, when using AP Style numbers writing out July 4 is okay, but stay away from July 4th.
Additionally, if you are writing about a decade or century, never use an apostrophe. The only time an apostrophe is needed is if you are writing a decade and dropping the first half of the figure (‘80s).
AP Style Years, Months, Decades and Dates Examples:
– The Renaissance spanned from the 1300s to the 1600s.
– The ‘70s were all about peace, love, and flower power.
AP Style Measurements and Dimensions
Use figures when writing about dimensions—including height and weight. Bonus: Don’t abbreviate the unit of measurement when using AP Style numbers.
AP Style Height and Measurements Examples:
– My grandma is approximately 4-foot-10.
– On average, a garden snail moves 50 yards per hour.
AP Style Highways
Follow the example of the popular Route 66 and use figures when writing about highways and freeways.
AP Style Highway Examples:
– You need to take Interstate 5 for 34 miles before you’ll reach your destination.
AP Style Millions/Billions
Always use figures.
AP Style Millions/Billions Examples:
– There are 300 billion stars in the Milky Way.
– It has been estimated that over 85 million house cats live in North America.
AP Style Money
Use figures when referring to money, whether dollars or cents. All of the numerals will carry dollar signs except when discussing cents. Note that when writing about an even amount, you want to drop the period and zeroes that often accompany a dollar amount ($6.00 = NO!).
AP Style Dollars and Money Examples:
– The business was sold for $5.7 million last year.
– Remember when a call from a payphone only cost 10 cents?
– I paid $6 for that hamburger.
AP Style Percentages
Use figures and the percent symbol to express percentages. (This was changed in 2019. Previously we had to write out “percent.”)
AP Style Percentages Examples:
– Approximately 25% of the world’s supply of hazelnuts is used to make Nutella.
– Only 9% of Americans prefer watching baseball more than other sports.
Try to avoid using a percentage to start a sentence, otherwise you have to write out the number and “percent.”
– Two percent of missing remotes are found outside.
AP Style Plural Numbers
Just like when writing about decades and centuries, an apostrophe should not be used with plural numbers.
AP Style Plural Numbers Examples:
– Yesterday I bowled two 300s.
AP Style Speed
Use figures with speeds.
AP Style Speed Examples:
– We were going at least 75 mph.
AP Style Temperature
Use figures with temperatures.
AP Style Temperatures Examples:
– Even though it was 43 degrees outside, he went swimming.
AP Style Time
Use figures with time. Note that you should never use :00 when discussing an even hour. Likewise, midnight and noon should be spelled out.
AP Style Time Examples:
– 5 p.m., 6:30 a.m.
Well-Known Expressions in AP Style
Ready for another exception? If you are using clichés or well-known expressions, you should usually spell out the number.
AP Style Expressions Examples:
– Life begins at forty.
– She had her fifteen minutes of fame.
