What size is a carry-on for Frontier?

Carry-On Baggage: Carry-On Bags can be no larger than 24? tall, 10? wide, and 16? long (including handles, wheels, and straps) and no heavier than 35 pounds.



For a 2026 flight on Frontier Airlines, it is vital to distinguish between a "Personal Item" and a "Carry-On Bag," as only the personal item is free. A Personal Item (like a small backpack or purse) must be no larger than 14" H x 18" W x 8" D and must fit under the seat in front of you. If you choose to pay for a Carry-On Bag to go in the overhead bin, the maximum dimensions are 24" H x 16" W x 10" D, including handles and wheels, with a weight limit of 35 pounds. Frontier is notoriously strict about these measurements; if your bag does not fit into the "sizer" at the gate, you could be charged a "Gate Bag" fee that often exceeds $100. For 2026 budget travelers, the "pro-tip" is to buy a bag specifically designed for Frontier's 18x14x8 personal item dimensions to maximize your packing space without having to pay the expensive carry-on fees.
