The men's Royal Rumble match is usually located at the top of the card, though there have been exceptions, such as the 1988, 1996, 1997, 1998, 2006, 2013, and 2018 events. Due to the Rumble match taking up a large amount of time (most Rumble matches last roughly one hour), the Rumble event tends to have a smaller card than most other pay-per-view events, which routinely have six to eight matches per card. The 2008 Royal Rumble was the first WWE pay-per-view to be available in high-definition. The 2018 Royal Rumble was the first to include a women's Royal Rumble match, which was the main event for that year; it is now standard for the event to include a men's and women's match. Since 2019, the Royal Rumble has been usually held in baseball stadiums.
