Delta Air Lines carry-on size and weight in 2026
Delta Air Lines (USA, IATA code DL) allows cabin bags up to 56 cm long, 35 cm wide and 23 cm deep; there is no separate weight limit as long as the bag fits the sizer.
The dimensions include wheels, handles and outer pockets. A soft bag can usually be squeezed a little, but a hard-shell suitcase cannot lose that extra centimetre — and that is exactly when gate staff ask you to pay.
Instead of guessing, open Kalibrator: pick Delta Air Lines, enter the size of your suitcase or bag and see in 3D whether it fits the sizer and where exactly it sticks out.
