Recorded in March and April 2017, the album was a collaboration between Malaysian and Indonesian composers, lyricists, and producers.

Pre-order for an exclusive edition of SimetriSiti was made available on Lazada Malaysia on 5 May 2017, and all 300 available copies sold out in 20 minutes.

In November 2016, she revealed that prior to her 3-week holiday trip,[4] she requested Aubrey Suwito to make an announcement on his Facebook page in search of new songs for her latest album.

"[8][b] The whole process, from vetting and finalizing the song candidates to recording the entire album took her and her team five months to finish.

[14] At early stages of the recording, she admitted that she had difficulty in singing some of the songs due to poor health.

[10] A last minute idea, she decided to pen and compose a song specially dedicated to her fans, "Penghiburku" (My Entertainers).

[10][11] She recalled the moment, "[I] didn't expect for "Penghiburku"'s melody to strike [my] mind when I was accompanying [my] step daughter-in-law.

"[11][c] When she submitted the demo to Sze Wan,[17] she suggested to Siti that some rapping to be included in the upbeat song which led to the involvement of Joe Flizzow to provide the additional verses.

[18] Apart from employing local Malaysian talents, Siti also sourced musicians and artists from Indonesia to contribute to the materials in SimetriSiti.

[13] Five songs from SimetriSiti, "Bersandar Cinta" (Out of Love), "Ikrar Cinta" (Love Vow), "Manis Terindah" (Sweet, Loveliest), "Segala Perasaan", and "Tak Perlu Ragu" received strings orchestra composition from Bulgarian National Radio Symphony Orchestra.

Unlike Fragmen, her previous studio album where she said it is more personal,[10] the title SimetriSiti was chosen by Siti because it represents the equal (symmetrical, in a sense) treatment given to each song in the album, from choosing the composers and songs, the way the lyrics were sung and up to the recording production in general.

[15][17] According to Siti, the Hollywood retro album cover was chosen because it represents her 21 years of journey as an entertainer.

"[11][d] The exclusive version of album, available only for pre-order on Lazada Malaysia, features a different cover,[23] complete with printed signature of hers.

[23] To promote the release of SimetriSiti, pre-order for exclusive version of the album was made available on Lazada Malaysia from 5 until 9 May 2017.
