Which U.S. presidents had the largest and smallest age gaps with their spouses?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
A clear historical answer exists in the compiled presidential marriage records: the largest documented spousal age gap belongs to John Tyler, who was 30 years older than his wife Julia (according to compiled lists), while the smallest recorded gap is the 92-day difference between Andrew Jackson and his wife Rachel [1] [2]. Contemporary lists that focus on recent presidents often highlight Donald Trump’s 24-year gap and sometimes mistakenly present different “smallest” examples when they limit their scope to modern first couples [3] [4] [5].
1. The biggest gap: John Tyler’s 30 years (and other large historical gaps)
John Tyler is commonly cited as the presidential spouse pair with the largest age disparity — a 30-year gap between him and Julia — a figure reproduced across compilations of presidential couples and summarized in overviews of historical age differences [1] [4]. Grover Cleveland is the next-largest frequently cited case, with a roughly 28-year difference between him and Frances Folsom, and more recent high-profile examples include Donald Trump and Melania Trump at roughly 24 years apart, a gap noted repeatedly in business and popular press lists [1] [4] [3]. These large gaps span different eras and contexts: Tyler’s marriage was a 19th-century norm in elite circles, Cleveland’s drew public attention because Frances was notably young when they married, and Trump’s gap became a persistent point of discussion in the 21st century [1] [4] [3].
2. The smallest gap: Andrew and Rachel Jackson’s 92 days (and why some lists differ)
Authoritative compilations of all presidential marriages identify Andrew Jackson and Rachel as the closest in age, separated by just 92 days — a difference that reportedly edged out Martin Van Buren’s couple by a single day in that dataset [2]. Not all media lists reproduce that finding because many outlets frame “smallest” as among modern or currently living first couples; for example, some lifestyle pieces list Joe Biden and Jill Biden as having one of the smaller gaps among recent presidents, citing about nine years’ difference, which is true for that contemporary subset but not the historical record as a whole [5]. The divergence stems from differing scopes: comprehensive historical rosters versus selective, topical lists focused on recent administrations [2] [5].
3. Averages and context: what “large” and “small” mean across presidencies
Summary data compiled by a presidential facts site reports that the average age difference across presidential marriages is about seven years, with first marriages averaging five years and the smaller number of presidential second marriages averaging around 15 years, underscoring that both very large and very small gaps are outliers against a modest mean [2]. That average helps put headline-grabbing examples — Tyler’s 30 years or Jackson’s 92 days — into perspective: most presidential spouses have been separated by less than a generation, and many differences fall within a decade [2].
4. Why reporting varies: scope, era, and editorial framing
Discrepancies in what outlets report as the “largest” or “smallest” gap usually come down to editorial choices: some outlets limit lists to living or modern presidents and first ladies and thus highlight Trump/Melania or Biden/Jill [3] [5], while others offer a full historical sweep that elevates 19th-century marriages like Tyler’s and Jackson’s into the extremes [1] [2]. Additionally, several popular articles emphasize contemporary cultural implications of age gaps rather than strict historical ranking, which explains why different pieces may emphasize different couples even when using the same underlying facts [4] [1].
5. Bottom line and limits of available reporting
The most defensible historical answer from the compiled records is that John Tyler’s marriage has the largest documented presidential spousal age gap at about 30 years, and Andrew and Rachel Jackson hold the smallest documented gap at 92 days; averages across all presidential marriages hover near seven years [1] [2]. If a different claim appears in media reporting, it usually reflects a narrower scope (for example, “modern presidents” or “currently living first couples”) rather than a contradiction in the underlying historical data [5] [3].
