List of Longest and Shortest Presidential Terms in U.S. History

When we think about a U.S. president's time in the White House, we usually think of a standard four-year or eight-year term. The Constitution sets up a four-year block for a reason, but history doesn't always go exactly according to the rule book!

Some presidents guided the country through massive transformations over more than a decade, while others had terms cut incredibly short by illness or unexpected tragedies.

Studying the lengths of presidential terms is a fantastic way to look at the unexpected twists and turns of American history. Here is a handy reference list of the absolute longest and shortest presidential terms, packed with the unusual stories behind the numbers.

The Longest Presidential Terms

1. Franklin D. Roosevelt (32nd President)

Time in Office: 12 years, 1 month, 8 days (4,422 days)

"FDR" holds a record that will never be broken. He was elected to the presidency a whopping four times! He led the nation through two of the biggest crises in modern history: the Great Depression and World War II. Because the country was dealing with such massive challenges, the American people kept voting to keep him in office to maintain stability.

The Historic Change: After FDR passed away in office during his fourth term, the country decided that having one person in power for that long wasn't a good idea for a democracy. In 1951, the United States passed the 22nd Amendment, which officially limited all future presidents to just two terms in office (a maximum of 8 years).

2. The Two-Term Trendsetters

Time in Office: Exactly 8 years (2,922 days)

Several presidents have served exactly two full terms. The very first was George Washington. Even though the people wanted him to run for a third term, Washington stepped down because he wanted to prove that the United States was a republic, not a kingdom run by a lifelong monarch. Other notable leaders who completed exactly two full terms include Thomas Jefferson, Andrew Jackson, Woodrow Wilson, Dwight D. Eisenhower, Ronald Reagan, Bill Clinton, George W. Bush, and Barack Obama.

The Shortest Presidential Terms

1. William Henry Harrison (9th President)

Time in Office: 31 days

William Henry Harrison holds the record for the absolute shortest presidency in American history. He gave the longest inauguration speech in history on a freezing, rainy March day in 1841 without wearing a coat or a hat. He caught a severe cold that quickly turned into pneumonia. Just one month after taking the oath of office, he passed away, leaving his Vice President, John Tyler, to take over.

2. James A. Garfield (20th President)

Time in Office: 6 months, 15 days (199 days)

Garfield was a brilliant man and a former teacher who had big plans to improve the country's education system. Tragically, just four months into his term, he was attacked by an angry man at a train station in Washington, D.C. Garfield didn't pass away immediately; he bravely fought the injury in his bed for several months while doctors tried to help him, but he ultimately passed away in September 1881.

3. Zachary Taylor (12th President)

Time in Office: 1 year, 4 months, 5 days (492 days)

Taylor was a famous military general known as "Old Rough and Ready." On July 4, 1850, he attended a hot, outdoor celebration at the Washington Monument. To cool down, he ate a large amount of fresh cherries and drank iced milk. He became severely ill with a stomach ailment that night and passed away five days later.

4. Warren G. Harding (29th President)

Time in Office: 2 years, 4 months, 29 days (881 days)

Harding was a popular president who loved traveling and meeting regular citizens. In the summer of 1923, he went on a massive traveling tour across the western United States and Alaska called the "Voyage of Understanding." The long trip was incredibly exhausting, and while resting at a hotel in San Francisco, he suffered a sudden heart attack and passed away.

5. Gerald Ford (38th President)

Time in Office: 2 years, 5 months, 11 days (895 days)

Gerald Ford is unique because he is the only person on this list whose short term wasn't caused by a tragedy. When President Richard Nixon resigned from office in 1974, Vice President Ford stepped in to finish the remainder of the term. He ran for election in 1976 but lost a close race to Jimmy Carter, meaning he never served a full four-year term of his own.
