We came up with this by an old experience. I ordered a screen protector once and it didn’t fit on my phone so we thought we could do the same problem for this. The name we came up with is Jerome, we came up with this name because we liked it the sound of it. The iPhone 8 Plus’s screen is 5.5 inches diagonally and the screen protector is 3.8 inches tall and 0.5 inches wide. Therefore the answer is no it will not fit on his phone because he ordered one for an iPhone 6.
