What Is Considered A Personal Item?
In most cases, the “personal item” is the small piece of luggage that you are entitled to take in addition to your carry on luggage.
It’s usually a handbag, purse, diaper bag, laptop bag, small daypack, or something of that nature. But sometimes your umbrella can count as your personal item too.
The TSA or the FAA don’t make the rules about personal items, each individual airline sets its own limits. Sometimes they can be pretty vague about it.
Any bag that is under the airline size limits will count as a personal item.
How Big Can A Personal Item Be?
You need to check with your airline what constitutes personal item size in their eyes. International airlines have similar rules.

Remember your personal item should go under the seat in front of you. If you chose a large personal item it can affect your legroom. Especially if you have long legs. Some people with short legs actually like to use a personal item as a footrest.
You shouldn’t really pack your personal item in the overhead bins. This leads to other passengers not having enough space for their carry on luggage.
You can use the Traveling Light Bagometer to check the capacity of your personal item bag.
What Makes For A Good Personal Item?
A good personal item should probably not have too rigid a shape. This will allow you to squeeze it if you need to make it fit under the seat. Small backpacks, small duffel bags or small weekender bags can make great personal item sized bags for this reason.
Some miniature under seater carry on luggage that might qualify as a personal item. But if you are stick in the aisle seat it tends to have less room you might struggle to fit it under the seat.

There isn’t a standard size for personal item luggage although 18 x 14 x 8 is quite common in the United States.
United have the smallest personal item size limit.
Budget airlines like Spirit and Frontier might be more strict about personal item size than full-service carriers.
They cut the prices of their flight and need to recoup that money elsewhere. Charging for oversized bags can be lucrative so they pay close attention.
