At 2,000 m², LOL is genuinely huge, with multiple play areas, sports space, slides and attractions for different ages. The venue itself and its Instagram both publish the 2,000 m² figure.
4. Maštograd

Maštograd combines a large indoor playroom with an equally large outdoor area. Its official information lists 800 m² in total, including themed rooms, a sports hall and a spacious garden play zone.
5. Naš Svet
📍 Zemun
👧 Published party package: up to 40 children
👨👩👧 Adults: up to 40
📱 Instagram: @igraonica_nas_svet
Naš Svet doesn't publish a floor-area figure, so capacity is the more useful measure here. Its own party packages go up to 40 children and 40 adults.
For a kids birthday party venue in Belgrade, always check current capacity, whether your group has a dedicated zone and whether the celebration is private or shared before booking.
