Standard Luggage Sizes: Your Ultimate Travel Guide

Why Knowing Luggage Sizes is a Travel Game-Changer

Oversize Baggage Fees Are No Joke

Getting slapped with a surprise baggage fee can sour the start of your trip fast. Airlines can charge hefty fees — sometimes up to $200 — just because your bag is a little too big. Knowing the rules helps you avoid these wallet-busting surprises.

Travel Light, Travel Smart

Picking the right-sized luggage not only saves you money, but it also makes getting through security, boarding, and even storing your bag a whole lot easier.

The Big Three: Personal Items, Carry-Ons, and Checked Bags

Let’s break it down. Airlines categorize your luggage into three main types: personal items, carry-ons, and checked baggage. Each category has its own size rules.

Standard Size for Personal Items

Personal items are bags that fit under the seat in front of you — think backpacks, laptop bags, or purses. U.S. airlines usually limit these to 18" x 14" x 8" or smaller.
