it does depend a lot on what you buy it for, but obviously 8' is a good benchmark.

But honestly... at 8' I'm not sure why you're bothering with anything (unless you're getting a lot of them), i usually just threw 8 footers in my Honda Fit and closed the hatch.

Ironically most pickup truck beds are shorter than 8' and most likely a 8' piece of lumber would have to lay diagonally sticking out over one of the edges.

Still good for occasional piece of furniture, lots of lumber, or plywood.

The shortest bed f150 you can buy is 5.5ft, with a 2ft tailgate, trivially hauling 8ft with just a few inches overhang with the tailgate down, and easily doing 10ft lumber.

Again, I think pickup trucks are idiotically oversized and dangerous to pedestrians, but arguing against them by repeating things that anyone that uses a pickup knows is nonsense is not helping win over any detractors.
