In an official release by the palace, the couple said they want their wedding to "be shaped so as to allow members of the public to feel part of the celebrations too.
"This wedding, like all weddings, will be a moment of fun and joy that will reflect the characters and values of the bride and groom," said the official statement.
The couple will tie the knot on May 19th, and asked that members of the public chosen to watch the wedding procession be "from a broad range of backgrounds and ages, including young people who have shown strong leadership, and those who have served their communities."
"Other guests will include 100 pupils from two local schools, 610 Windsor Castle community members and 530 Members of The Royal Household and The Crown Estate." Kensington Palace said in an official statement.
Many of Prince Harry and Meghan's charity organisations appear on the guest list, with some 200 expected from organisations the couple has a close association with, including those Harry is a patron of.
