Small correction: Wilt Chamberlain had a 9'6" standing reach in Converse Chuck Taylors, not barefoot. According to Celebheights, Chuck Taylors add 0.7" of height:
https://www.celebheights.com/sneakers/2.html So, Wilt's average modern shoe 1.25" adjusted standing reach would be around 9'6.5". That's assuming the classic Converse Chuck Taylor All-Stars design has remained unchanged since the '50s. Which I believe to be true.
In my opinion, the three closest guys proportions-wise to Bill would be Giannis Antetokounmpo, Mark Williams (drafted 2022), and a Nigerian who was measured at the 2009 Eurocamp called Aboubakar Amadou/Roger Zaki. All three have narrower clavicles that suppress their wingspan measurement which understates the length of their arms, high-set shoulders, shorter necks, smaller heads, and flexible shoulders. Here are their measurements:
Mark Williams:
- 7'0" barefoot height
- 7'6.5" wingspan (9" hand length)
- 9'8.25" standing reach (1.25" shoe adjusted)



Giannis Antetokounmpo:
- drafted at 6'9" and experienced a growth spurt. Celebheights has him at 6'10.5" barefoot.
http://journaltimes.com/sports/basketball/bucks-beat-antekokounmpo-green-but-growing/article_c3048dda-5bd5-11e3-ad1c-001a4bcf887a.htmlNot only is Antetokounmpo’s game growing, so is his body. When the Bucks drafted him in June, he was 6-9. Now, just more than five months later, he has added more than an inch to his lanky frame.
“I am now 6-10 and one quarter,” Antetokounmpo said smiling…
- 7'3" wingspan according to DraftExpress leading up to the draft. Could potentially be 7'4" or 7'5" now. Listed as 7'4" in some articles. 9.8" long hands.
Adetokunbo stands out first and foremost thanks to the tremendous physical profile he brings to the table, reminding somewhat of a Nicolas Batum or Thabo Sefolosha on first glance. He has great size at 6-9, 196 pounds, to go along with a developed upper body and an overall terrific frame that should fill out considerably in time.
His wingspan has reportedly been measured at 7-3, but perhaps most interesting is the size of his hands, as he's able to palm the ball like a grapefruit which helps him out considerably as a passer, ball-handler and finisher.

https://www.nbcsports.com/nba/news/bucks-rookie-giannis-antetokounmpo-is-still-physically-growingWhen measured at Adidas EuroCamp last year, Greece’s Giannis Antetokounmpo measured 6’9” with a reported 7’3” wingspan.
- No official standing reach measurement. Recorded a max vertical reach of 12'2" in May of 2015. Has routinely displayed an ability to hang off the rim and touch the ground on his tippy toes at the same time. Some have estimated his standing reach to be somewhere in the 9'5" to 9'7" range.


Roger Zaki:
- 6'10.25" barefoot height
- 7'5" wingspan
- 9'6.5" standing reach (1.25" shoe adjusted)
