United states the carry-on maximum as 9 x 14 x 22 inches (22 x 35 x 56 cm). The carry-on is fare-dependent (check your fare rules).
As a box, United's carry-on limit holds about 43 litres on the outside. Hardside cases lose roughly a tenth of that to the wheel wells and handle channel.

How does United's carry-on limit compare?
By volume, United's box is larger than 2 and smaller than 15 of the 27 carry-on limits on this site. Within a centimetre on every side, it is the same box as American, Delta, Alaska, JetBlue and Hawaiian. Spirit, easyJet and Frontier publish the most generous limits. The tightest published limits are Icelandair and Ryanair, so a bag bought for United can fail there.

Frequently asked questions
What is the United carry-on size limit?
United Airlines’s own baggage page gives the carry-on limit as 22 x 14 x 9 in / 56 x 35 x 22 cm. United states the carry-on maximum as 9 x 14 x 22 inches (22 x 35 x 56 cm). Measure the bag with wheels and handles, standing up, and compare the longest side with the longest limit.
Does United weigh carry-on bags?
The United page read for this site states no carry-on weight limit. That does not mean any weight is fine: you must be able to lift the bag into the overhead bin yourself, and gate agents can still check a bag that does not fit.
Will a 22 x 14 x 9 inch bag fit United?
Yes. A bag measuring exactly 22 x 14 x 9 inches with wheels meets United’s published carry-on limit, with 0 in to spare on its tightest side. Bags whose listed size excludes wheels are often an inch or two longer in reality, so check the wheels-included figure.
Is the United carry-on included in the fare?
On the page read for this site, the carry-on is fare-dependent (check your fare rules). Basic or light fares at some airlines restrict the overhead bag, so confirm what your specific ticket includes before you pack.
Researched, not professional advice. Airline limits change without notice and can differ by route, aircraft and fare; the airline's own page is the final word.
