Presidents popularly known by middle names or nicknames 
- Hiram Ulysses Grant went by Ulysses
- Stephen Grover Cleveland went by Grover
- John Calvin Coolidge, Jr. went by Calvin
- Thomas Woodrow Wilson went by Woodrow
- James Earl Carter, Jr. went by Jimmy
- William Jefferson Clinton went by Bill
Only one president's original full name, Hiram Ulysses Grant, forms an English word ("hug"). After a clerical error at West Point entered his name wrongly as Ulysses Simpson Grant, and since he disliked the acronym, Grant went along with the change.
Duplicates and multiple first names 
There have been:
- (6) James(Madison, Monroe, Polk, Buchanan, Garfield, Carter)
- (5) John(Adams, Quincy Adams, Tyler, Coolidge, Kennedy)
- (4) William(Harrison, McKinley, Taft, Clinton)

Length of first names 
- Rutherford is the longest Presidential first name at 10 letters.

Middle names 
- Three Presidents used their middle name as their given name:
- Seventeen of the 43 presidents to date have no known middle name.
- Franklin Pierce is sometimes referred to as Franklin K. Pierce: the 'K' possibly standing for his mother's maiden name of Kendrick. However, there is no evidence that Pierce was given a middle name at birth or ever used a middle name or middle initial.
- Several Presidential middle names were originally surnames: Baines, Birchard, Delano, Fitzgerald, Walker, Knox, Milhous, Quincy, and Simpson, et al. Most of these were the President's mother's maiden name.
- Gerald Rudolph Ford was born Leslie Lynch King, Jr. therefore giving him the middle name of Lynch before his mother remarried when he was three years old; his name was not legally changed until 1935 while in law school.
- Ulysses S. Grant was born Hiram Ulysses Grant. His name was wrongly entered as Ulysses S. Grant when he entered the United States Military Academy.
- Harry S. Truman's middle name was only an initial; the "S" didn't stand for another name. Nevertheless he signed his name using the period after the letter.
- George Herbert Walker Bush is the only President with two middle names.
- There are no duplicate Presidential middle names, with the partial exception of Herbert Walker and Walker.
- Two Presidents have middle names which are also Presidential last names: Ronald Wilson Reagan and William Jefferson Clinton.
Last names 
- There have been two Adamses, two Bushes, two Harrisons, two Johnsons, and two Roosevelts. All of the pairs except the Johnsons were related to each other.
- Thirty-three of the Presidents have had unique last names.
- Eisenhower and Washington had the longest last names, with 10 letters each.
- Twelve Presidents have last names of three syllables: Washington, Jefferson, Madison, Van Buren, both Harrisons, Buchanan, McKinley, both Roosevelts, Kennedy and Obama.
- Eisenhower is the only President whose last name is four syllables long.
- The Bushes, Taft, Polk, and Ford had the shortest last names, with four letters each and only one syllable each. Three other Presidents have longer last names that are still only one syllable: Pierce, Grant and Hayes for a total of seven single syllable last names.
- The remaining Presidents (so far) have names of two syllables regardless of length
- The average Presidential last name has 6.64 letters.

Last name suffixes 
Twelve presidents were complete namesakes of their fathers':
- John Adams, Jr.
- James Madison, Jr.
- Andrew Jackson (it is unknown if he ever went by "Jr.")
- John Tyler, Jr.
- James Buchanan, Jr.
- William McKinley, Jr.
- Theodore Roosevelt, born Theodore Roosevelt, Jr.

George Walker Bush does not share exactly the same name of his father, George Herbert Walker Bush, nor does John Quincy Adams share his exact name with his father John Adams. This has not, however, deterred the press from referring to George W. Bush as "George Bush, Jr."
