> if it wasn’t for the fact that the 12 and 13 mini were larger than the iPhone 6 and 6S which for many people was too large.
I don't get why people make statements like this.
6: 2.64 (W) x 5.44 (H) x .27 (D)
6s: 2.64 (W) x 5.44 (H) x .28 (D)
13 mini: 2.53 (W) x 5.14 (H) x 0.30 (D)
The only dimension in which the mini was larger than the 6 or 6s was in depth, and that was just barely. It was smaller otherwise.
It did have a larger display, but it fit it into a smaller device.

All iPhones before the iPhone 6 were smaller than the 12 and 13 minis. The 1st gen SE was smaller. Everything from 6 on, including the 2nd and 3rd gen SEs, have been larger, though barely for the SEs. The downside to the SEs compared to the minis was that they have smaller displays than the minis.
