It’s best practice to hang drywall in a vertical direction on walls to reduce to a minimum all abutting joints. If when you lay the drywall sheets, there are no studs you can use to screw the sheets to a stud, then grab a 2 x 2 and nail it to the stud so you have a solid stud where to lay the sheet, this way the edges of the sheets will have a solid surface to attach the drywall sheet.
In order to hide abutting joints where two bare drywall sheet ends come against each other, the easiest way is to create a thin and wide hump using joint compound. Even though this is not rocket science, it takes time to create a perfect match. Avoiding abutting joints is the smartest way to go if you're an amateur drywall finisher installer.
The best way to avoid abutting joints is to utilize drywall sheets with the full length to wrap complete walls and ceilings. Consequently, you'll only have taper off joints to finish. Drywall sheets generally come in 8- and 12-ft. lengths, but specialty suppliers have 14-ft. sheets available.
Only when your ceiling is longer than 14 ft., you won't be able to dodge abutting joints. On the other hand, you can evade abutting joints on walls that surpass 14 ft. in length. The key to this secret is to hang the drywall sheets vertically instead of horizontally. Using this method, you'll have several dwindle joints to cover, but no abutting joints. Installing drywall in a vertical fashion is slower than installing it in a horizontal fashion because you have to make sure the dwindle edges meet at the stud’s center. Cut the first drywall sheet to the proper width, so the dwindle edge arrives right on the stud’s center. Once you are able to accomplish this, the edges of each subsequent sheet should land perfectly on the studs. If you come across studs placed at irregular intervals, attached 2x2s to them. When your ceiling is 9-ft. high, contact a drywall specialty supplier to get 10-ft. sheets.
