On a SuperCrew (full size, four door cab) the front and rear door speakers are all 6″ x 8″.
I can’t speak to regular cab or SuperCabs – they might be different.
(by the way – thanks for the wiring color codes – it really helped me a LOT to wire in an aftermarket stereo and speakers)
Thanks! I updated the listing.
