There are over 160 RuneScape servers located throughout the world, which are numbered and referred to as worlds by players and by Jagex. They are located in the United Kingdom, the United States, Canada, the Netherlands, Australia, Sweden, Finland, Belgium, Mexico, Brazil, Ireland, Norway, Denmark, New Zealand, and France.[25] The large number of servers scattered around the world provides the best connection for players in the most cost-effective manner. Servers are moved or added as the need arises.[26]

Each RuneScape server allows up to 2,000 players to connect simultaneously,[27] allowing a maximum capacity of more than 320,000 players.It is hard for to when there are too many players in this server. The servers are divided into free servers which are available for all players, and servers which are reserved for paying members. Players can play on any eligible server.[28] Some servers are given activity labels, allowing players performing tasks that require or desire group participation, such as mini-games, to group together.[29] In addition to the RuneScape servers, there are two members-only servers for RuneScape Classic, both located in the United Kingdom. Each of these is limited to 1,250 players, allowing a total number of 2,500 simultaneous RuneScape Classic players. Players can no longer create new accounts for RuneScape Classic.[13]
