In a great piece for Sports Illustrated about 7-foot NBA players, author Pablo S. Torre estimates that the number of American men between the ages of 20 and 40 who are 7 feet or taller is likely below 70.
During the 2017-2018 NBA season, there were 20 American players who were at least 7 feet tall. So, if the estimates above are correct, that would mean that there is a whopping 28% chance that you are going to make it to the NBA if you are at least 7 feet tall!
Now maybe you don’t need to grow to 7 feet to make it to the NBA, but there is no denying that body height is a huge advantage in basketball. In this article, I want to take a closer look at the average height of NBA players across different positions and how it changed during the history of the NBA.
How tall are NBA players?
In the 2017-2018 NBA season, the average basketball player was 6’7″ tall (200.4cm) which is almost 10 inches taller than the average American male (5’9 1/2″)!
But have basketball players always been that tall?
If we take a look at the average height of NBA players during the history of the league we can see that basketball players in 1952 were almost 3 inches smaller than today! After that, players continuously grew taller until the apex was reached in 1987 at 6’7″ tall (201.2cm). Since then there were only slight fluctuations from year to year, but it seems as if a plateau was reached around 6’7″.
Interestingly, while average player height has stopped growing in 1987, players continued to get heavier until 2011 when they reached the peak of 221 lbs. This correlates with the NBA becoming more athletic, powerful and muscular.
This trend has stopped during the last years as basketball is becoming become a much faster, and more perimeter-oriented game, so it makes sense that players are getting leaner again.
Evolution of Player Height & Weight in the NBA from 1952-2018
Average player height only tells half of the story. It doesn’t give you insights into how height is distributed among the players. Is every player exactly 6’7″, or are there a ton of guards around 6 feet and a lot of centers around 7 feet and it just happens to average out to 6’7?
If we take a look at the chart below we can, for example, observe that NBA players at 6’8″ were most common and accounted for 12.2% of all minutes played.
Distribution of Height in the NBA in 2018
At the extremes, you will notice that there were only 20 players at 6 feet or below (4% of playing time) and 45 players at 7 feet or taller (8.8%)
Overall, we observe a big concentration of players between 6’6″ and 6’10” – these players made up over half of all minutes played (51.1%)!
If we consider how common a body height of 6ft is among the general population and how few of them make it to the NBA, it becomes obvious just how skilled and insanely rare All-Stars like Chris Paul are!
How tall do you have to be play in the NBA?
Your dream is to make it to the NBA one day? I guess it doesn’t come as a surprise that this dream is much easier to realize if you are tall.
But just how tall do you need to be?
This calculator allows you to compare yourself to all NBA players who play at your position: Just pick your height, weight, and position and it will tell you how you stack up to NBA players! Just for fun, you can also compare yourself to players of other decades!
How tall are Point Guards in the NBA?
We can see that point guards were smallest during the 1952/53 season with an average height of around 6 feet. Since then, they have grown taller almost every year until they reached a peak in 1987 at 6’3″. During this time, big point guards like Magic Johnson at 6’9″ or Reggie Theus at 6’7″ were among the leaders in minutes played in the NBA.
Only 4 years later, in 1991, the average point guard had shrunk back to 6’1″ with tiny players like Spudd Webb (5’6″) and Muggsy Bogues (5’3″) getting major minutes.
During the 2017/2018 season, point guards reached a new record height (6’3) with 6’10” rookie Ben Simmons being third in minutes played.
Overall, it feels like average player size at the point guard position is less determined by trends and more by player talent. If you have a legendary playmaker like Magic Johnson you make him your point guard, even if he has a power forward body. But no coach would put a regular power forward at point guard just to increase size at this position. Basketball IQ and understanding of the game are much more important at this position!
During the 2017/2018 season, the most common height for point guards was 6’3″, examples are players like Russell Westbrook, Steph Curry or Damian Lillard. The biggest Point Guard was Ben Simmons at 6’10, the smallest was Isaiah Thomas at 5’9.
Average Height of Shooting Guards in the NBA
In comparison to point guards, the change in height of shooting guards was more of a steady rise that has reached a plateau at 6’5″ around the year 2000.
Interestingly, the tallest shooting guard in 2017/2018 (Corey Brewer at 6’9″) was smaller than the largest Point Guard (Ben Simmons at 6’10). We can also see that the distribution of player sizes is much narrower for shooting guards – almost all shooting guards are somewhere between 6’3 and 6’7!
This makes sense when you consider that the roles of shooting guards and small forwards are pretty similar, so if you’re a 6’9″ wing, you’ll probably just be classified as a SF not a tall SG, even if you technically play the SG role.
NBA Height of Small Forwards
Small Forwards have been getting almost continuously bigger over the years: they started at 6’4″ in 1952 and peaked at 6’8 in 2015. Interestingly, they are almost exactly 2.5 inches taller than the average shooting guard every year, which shows you that wings, in general, are getting bigger.
Similar to the SG position, the SF positions seems to be very well-defined with a majority of players measuring in somewhere between 6’6″ and 6’9″.
How tall are Power Forwards in the NBA?
The power forward is probably the position which has changed the most in the modern NBA. PF’s used to be big and strong low post players who battled for rebounds and scored on post-ups, but players like Dirk Nowitzki have completely changed the game. Nowadays, power forwards are often used to stretch the floor shooting a lot of threes and acting as playmakers on the perimeter.
Surprisingly, this change of playing style is not reflected at all in the average height of power forwards. Since 1987, they are on average 6’9″ tall with very little year-to-year fluctuation. However, the average power forward in 2018 weighs almost 10lbs less than in 2014!
It’s often said that the NBA is getting smaller, but this data suggests that power forwards are not getting smaller – just leaner and more skilled!
How tall are Centers in the NBA?
Centers show a very similar trend as Power Forwards. While average height reached a peak in 1996 with almost 7 feet, average weight continued to increase steadily until 2014 when it maxed out at 255lbs.
There is very little variety among centers when it comes to height: almost 60% of centers are either 6’11 or 7″. Giants like Boban Marjanovic at 7’3″ are very rare – even in the NBA!
Data Sources & Notes
Data was collected from basketballreference.com . There are a few shortcomings of this data:
- Players are assigned a single position per season. In reality, a lot of players play multiple positions every game. For example, some players start games as a shooting guard but take over point guard duties with a bench unit later.
- Height and weight data is registered once per player. This means that the data has Shaq weighing exactly 325lbs every season, and we all know that that’s not true
- If you take a look at distributions over multiple seasons, players are counted once per season. This means, that if the graph says there were 3 players at 5’3 from 1992-1995, it refers to three seasons of Muggsy Bogues, not three different players
