Why does drywall only have 2 tapered edges?

Why does drywall only have 2 tapered edges? This makes no sense to me since its easier to tape and mud a tapered edge. I cannot find the answer to this from anyone or on the internet.

Thank you,

Because you will inevitably have a cut edge at some point, and taping a cut edge into a tapered joint is a real PITA!

Another reason is the way that drywall is made.

Spruse is correct in it is the way it is made.
Made on a conveyer belt and is cut to the correct length 8-9-10 0r 12 feet. also will cut special order lengths.In manufacturing the starting lenght on the belt may be up to 700 feet before being cut.

both valid points, special order drywall can also be 4'6 wide or 5', and lenghts of 14, 16, 18, ive heard of 20 ft but anything over that just isnt practical.. its too heavy to carry and too much chance of breaking not to mention deliver to a site

Hi,
this q brings to mind the old Fine Homebuilding trick of having wallboards terminate between studs (not on studs, as normal practice dictates), where special blocking would be set below the surface of the stud wall plane 1/4" to bow the butt ends of the rock down, in effect giving you completely flush seams on all four edges. People have done it, myself not among them. It's very fiddly, but it has been proven to work and with a 16" knife you can achieve perfectly flat wall planes. Probably best suited for high-gloss wall finishes, where even the best floated seams would be detectable simply because they have to stand out and have mud beyond the face of the paper.
