• The song is the fifth track on Ed Sheeran's third studio album ÷, which was released in March 2017, three years on from his previous release.
• "Perfect" is a romantic ballad written about his girlfriend Cherry Seaborn, which Sheeran said he hoped would become another one of his defining songs and, according to the BBC, is 'guaranteed to soundtrack thousands of first dances before the year is out'.
• In an interview with Zane Lowe, Sheeran said "I just wanted to beat "Thinking Out Loud" because I know that song was going to define me...With "Perfect", it was like, I need to write the best love song of my career".
• Sheeran revealed that inspiration behind the song came after visiting James Blunt's house, where the two singers had listened to the rapper Future's
music. Sheeran said 'Barefoot on the grass, listening to our favorite song' happened to be Future's "March Madness". But I had that 'We were just kids when we fell in love, not knowing what it was, I will not give you up.'... And I had that and I was like, right, let me just flesh that out. And the song happened and was sort of finished that day. I knew it was special."
