2x4s come in various lengths and are cut at the lumber yard to fit your exact measurements. So go prepared and you'll look like a pro.
You can get many lengths. The most used are 93 1/4 inches (called "precut" studs) 8 feet, 10 feet, 12 feet, 16 feet, some lumberyards will sell 82 1/2 inch precuts for jackposts
Crazy has it, mostly. 2x4's come in even foot numbers usually. 6, 8, 12, 16, & 20 I beleive
