The O2 Arena in London can hold up to 20,000 people for most concerts. That’s roughly the entire population of a small town, all crammed into one giant, glowing dome. For basketball or other sports, it shrinks a little, to about 18,000, but that’s still a lot of hot dogs and high-fives. Twenty thousand is the magic number you’ll hear most often.
A Comparison You’ll Actually Get
Imagine your local cinema where you watch the new Marvel movie on opening night. That room holds maybe 300 people if it’s huge. Now imagine sixty-seven of those full cinemas, all stacked together in one room. Or picture a sold-out football match at your local park, but instead of a grassy field, everyone is under one roof, staring at a stage. That’s the O2.
It’s also like having the entire capacity of a Boeing 747 jumbo jet (about 400 people) and multiplying it by 50. Fifty jumbo jets of screaming fans, all singing along to the same song. Suddenly, “capacity” feels a lot more personal, doesn’t it?
