USA TODAY NETWORK - Florida Barron Trump, the sole child of Donald and Melania Trump, is the tallest in the Trump family — and has been for years. Barron, a college freshman at NYU, bucked Trump family tradition by not attending University of Pennsylvania or Georgetown University. Barron Trump's attendance at his father's Election Night watch party in Palm Beach, Florida, was his 2nd official campaign appearance in the 2024 presidential election. No contest: Barron Trump is the tallest member of the Trump family. After his "proud mom" Melania Trump tweeted a viral photo of her very tall 18-year-old son voting on Election Day 2024, search engine queries about Donald Trump's youngest son's height spiked the morning after. The Palm Beach Daily News, a USA TODAY Network newspaper, reported early Tuesday, Nov. 5, that Donald and Melania Trump voted at the Mandel Recreation Center near Mar-a-Lago in Palm Beach. It wasn't known at the time whether Barron Trump cast a ballot there − until Melania Trump's tweet. As of 10 a.m. Wednesday, Nov. 6, the tweet has already been viewed more than 11.6 million times. Its message? "Voted for the first time - for his dad! #18yearsold #presidentialelection #proud" Though the photo of Barron Trump does not show his face, it is on the official X account (formerly known as Twitter) of Melania Trump, and it's a view of him from the back with very long legs. How tall is Barron Trump, son of Donald and Melania Trump?
