Considered a "classic" Disney song, "Part of Your World" has since established itself as both "The Little Mermaid"'s hallmark song and signature ballad. Believed to be responsible for introducing "Disney's Broadway age", the song is also credited with making the "I Want" song a popular staple of future animated Disney musical films, at the same time introducing film audiences to a period known as the Disney Renaissance. "Latina" contributor Sally Mercedes dubbed the song "one of the most memorable Disney songs ever". "Part of Your World" is also considered Benson's signature song, which she has yet to grow tired of singing. Benson believes that the popularity of the song is one of the main reasons "The Little Mermaid" was instrumental in helping revive the animated film genre during the 1990s. HitFix contributor Donna Dickens credits much of the film's success with Benson's performance of the song. "Time" selected "Part of Your World" as one of the Disney Renaissance's most iconic moments, writing, "If you are a female-identified child of the ‘90s, chances are good that you have belted this song into your hairbrush or showerhead on more than one occasion." "Billboard"'s Erin Strecker agreed that "every single child has sung ['Part of Your World'] into a hairbrush". MetroLyrics considers "Part of Your World" to be among "21 Disney Songs That Are Still The Soundtrack To Our Lives". Yahoo! Movies contributor Gwynne Watkins crowned the song "one of Disney’s all-time greatest character songs". Amy Valm of "Today's Parent" believes that "Part of Your World" resonated particularly strongly among millennial audiences, crediting it with introducing many of them to the word "reprimand". Music streaming service Deezer revealed that "Part of Your World" was the 19th most streamed Disney song of 2017. It is also one of the "most enduring" songs in the Disney canon, and remains of one the studio's most popular songs to-date.
