The Pixel 4 is basically the same size as a standard iPhone (Pixel 4: 147.1 x 68.8 x 8.2 mm, iPhone 17: 149.6 x 71.5 x 7.95 mm, iPhone 17e: 146.7 x 71.5 x 7.8 mm).

I don't think most people realize that. The iPhone mini was essentially a category on it's own (iPhone mini 13: 131.5 x 64.2 x 7.65 mm)
