Five of the six teams playing in Group B are staying in the same four-star hotel in Germany's capital, which has had to order special extensions to their beds as 25 of the basketballers measure over two metres tall.
"We had a total of 40 beds lengthened," a hotel spokeswoman told the Berliner Morgenpost newspaper.
Germany's centre Tibor Pleiss and Iceland's Ragnar Nathanaelsson are the tallest players of the Group B teams as both measure 2.18m.
The pair will square off in Saturday's opening match in Berlin between Germany and Iceland with Spain, Serbia, Italy, and Turkey also in Group B in Berlin.
Germany's NBA star Dirk Nowitzki, the Dallas Mavericks' power forward who stands at 2.13m, has rented a separate apartment in the hotel for his family.
After Ukraine pulled out of hosting this year's European championships, the four group stages are being spread around Europe with Montpellier, Zagreb, Riga and Berlin hosting before the knock-out stages continue in Lille, France.
