The standard size for a carry-on bag is usually around 22 inches tall, 14 inches wide, and 9 inches deep, but don't worry, I won't make you memorize those numbers. Just know that if your bag is bigger than that, you might be in trouble. And trust me, you don't want to be that person who holds up the entire flight because their bag won't fit in the overhead bin.
Now, I know what you're thinking: "But what about all my essentials?" Don't worry, you can still pack all your must-haves, from your favorite sweater to your laptop. Just be sure to measure your bag before you leave for the airport, or you might end up having to repack everything at the gate.
