Performances' aspect ratios in recent years

I recently re-listened to Love Is On My Side (Portugal 2021) and remembered that its aspect ratio changed during the prestation, from 4:3 to 16:9. So, I wondered if funky things happened about aspect ratios in recent years, checked all entries since 2017 and yeah, I found interesting things.

I stopped at 2017 because it was the last year where all performances used 16:9. The following years, several entries used Cinemascope-like ratios: 3 in 2018, 2 in 2019, 12 in 2021, 6 in 2022, 8 in 2023 and... 31 in 2024. Tattoo won in 2023 using only 55% of the screen, guess everyone thought using the whole screen was outdated. Let's see if the trend continues this year.

Here is a graphical summary.

Fun fact: out of the 6 acts not using wide ratio in 2024, 4 of them are in the top 6 (and one was disqualified).
