What is the size of a personal carry-on?

Including handles and wheels, the maximum dimensions for a carry-on are 22 inches long, 14 inches wide and 9 inches high. Personal items are limited to 17 inches long, 10 inches wide and 9 inches high.



A "personal item" in 2026 is generally defined as a bag that can fit completely under the seat in front of you. Most major airlines, like United and American, set these dimensions at roughly 18 x 14 x 8 inches (45 x 35 x 20 cm). This typically includes small backpacks, laptop bags, or large purses. It is smaller than a "standard carry-on," which goes in the overhead bin and is usually 22 x 14 x 9 inches. For 2026 travelers on "Basic Economy" tickets, the personal item is often the only free bag allowed. If your personal item is too bulky to fit under the seat, or if you try to bring a second bag without paying, you may be forced to gate-check it for a fee that can range from $35 to $65, so it is a "pro-tip" to use a soft-sided bag that can be squished into a sizer if necessary.
