So, what are the TSA quart size bag dimensions, you ask? Well, according to the TSA, the bag has to be 7 inches wide, 8 inches tall, and 2 inches deep. That's right, it's like a tiny little suitcase, but instead of clothes, you get to pack all your favorite shampoos and lotions.
Now, you might be thinking, "What's the big deal about the size of the bag?" Well, the TSA is very serious about these rules, and if you show up at the airport with a bag that's too big, they'll just laugh at you and make you throw away all your precious liquids. Okay, maybe they won't laugh, but they will definitely make you take everything out and re-pack it, and that's just a hassle.
But don't worry, it's not all doom and gloom. The TSA also allows you to bring some exceptions on board, like medications and baby formula. Just make sure you declare them at the security checkpoint, or you might find yourself in a bit of a sticky situation.
