Measure at the widest points, including wheels, handles and pockets.
Most airlines limit checked bags to 158 cm in total. That is the length, width and height added together, including wheels and handles, or 62 in. Economy usually allows 23 kg (50 lb) and premium cabins 32 kg (70 lb). A 75 × 50 × 30 cm case comes to 155 cm, just inside.
