Shortest Person to Dunk a Basketball: Breaking the Height Barrier

The shortest widely documented person to dunk a basketball on a regulation 10-foot rim is Brandon Todd, who stands 5 feet 5 inches and trained himself into a 45-inch-plus vertical leap. In professional basketball, Spud Webb (5 feet 7 inches) holds the record as the shortest player to dunk in NBA games and the shortest ever to win the Slam Dunk Contest. Below about 5 feet 5 inches, verified cases nearly vanish.

What the record actually measures

The rim doesn’t move for anyone. It sits at 10 feet whether you’re 7 feet tall or 5 feet 7, so a shorter player chasing a dunk is really chasing a much bigger number on the vertical jump test than everyone else in the gym. “Shortest dunker” is therefore two records braided together: the smallest stature and the largest required leap.

That distinction matters because unverified claims are everywhere. A credited record needs a documented height, a regulation rim, and footage or eyewitness accounts that hold up. Judged by that bar, the honest floor sits around 5 feet 5 inches, where Brandon Todd and Spud Webb operate, not the sub-5-foot claims that circulate online.

The physics of dunking at low heights

To dunk, your hand has to clear the rim by a few inches at the top of your jump. Lose height, and the vertical leap required climbs fast.

Height	Standing reach (approx.)	Vertical needed to dunk
6 ft 0 in (1.83 m)	~7 ft 10 in	~26-28 in
5 ft 9 in (1.75 m)	~7 ft 6 in	~30-32 in
5 ft 7 in (1.70 m)	~7 ft 3 in	~33-36 in
5 ft 5 in (1.65 m)	~7 ft 0 in	~40-45 in
5 ft 3 in (1.60 m)	~6 ft 9 in	~44-48 in

Every lost inch of height adds several inches to the vertical leap needed. By the time you’re down at 5 feet 3 inches, you’re asking a human body to do something close to its physical ceiling, which is why the record thins out so quickly below 5 feet 7.

The short dunkers, ranked by stature

Spud Webb, at 5 feet 7 inches, is the clearest professional case of a short player dunking repeatedly and with real power. His 1986 Slam Dunk Contest win over teammate and defending champion Dominique Wilkins (6 feet 8 inches) is still one of the sport’s defining moments, sealed with two perfect 50-point scores and a reported 42-inch vertical.

Brandon Todd, at 5 feet 5 inches, is the most credible non-professional record holder. He spent years studying Russian powerlifting methods, added roughly 80 pounds of muscle, and pushed his vertical past 45 inches until he could throw down on a regulation rim. His story became a viral short film and a message about not writing off short athletes.

Muggsy Bogues, at 5 feet 3 inches, is the shortest player in NBA history and is asked about dunking constantly. He has said he could dunk with his reported 44-inch vertical, but there is no confirmed footage of him completing one in an NBA game, so he is not credited among documented dunkers.

Nate Robinson and Isaiah Thomas, both listed around 5 feet 9 inches, dunked routinely in games and events. Robinson built his three-time Slam Dunk Contest legacy on exactly that explosive athleticism.

Leaderboard: shortest documented dunkers

Rank	Name	Height / vertical	Context & year
1	Brandon Todd	5 ft 5 in / 45+ in	Self-trained dunk on regulation rim, documented ~2013-14
2	Spud Webb	5 ft 7 in / ~42 in	Won NBA Slam Dunk Contest, 1986
3	Nate Robinson	5 ft 9 in / ~40+ in	3x NBA Slam Dunk Contest champion (2006, 2009, 2010)
4	Isaiah Thomas	5 ft 9 in / high	Dunked in NBA games, 2010s
—	Muggsy Bogues	5 ft 3 in / ~44 in	Claims ability; no confirmed NBA game dunk

Heights are official listings and verticals are widely reported figures; treat them as close estimates rather than laboratory-measured marks.

How short dunkers train to close the gap

Shorter athletes chasing a dunk usually build around a few pillars:

• Plyometrics: box jumps, depth jumps, and jump squats for explosive power
• Strength work focused on the posterior chain (glutes, hamstrings, calves)
• Approach mechanics, since a clean two-step or one-step run-up can add real inches to effective jump height
• Core strength, needed to transfer ground force efficiently through the jump

The short dunkers who make it look easy are rarely just strong-legged. Their whole kinetic chain, hips through ankles, works together. Brandon Todd’s transformation is the clearest proof: he treated the dunk as a multi-year strength-and-power project rather than a party trick.

The live chase in 2024-26

The record remains open at the very bottom. As of 2026, no one under roughly 5 feet 5 inches has an independently verified regulation dunk, and social media keeps producing challengers who claim to have broken that barrier. Most clips fall apart on inspection, showing lowered rims, smaller balls, or camera angles that hide the truth.

That is exactly why the barrier holds cultural weight. Every February, a new crop of short leapers goes viral for the same reason Spud Webb did in 1986: fans assume height is a prerequisite, and each verified short dunk proves the assumption wrong. Until someone documents a clean regulation dunk below 5 feet 5 inches under credible conditions, Brandon Todd and Spud Webb remain the names the record runs through.
