For travel on a Greyhound bus in 2026, the luggage policy allows you to bring one "personal item" on board and one larger suitcase to be stored under the bus for free. The maximum size for your checked suitcase is 62 linear inches (calculated by adding the length + width + height) and it must not weigh more than 50 pounds (23kg). If your bag exceeds these dimensions or weight, you will be charged an "oversize" or "overweight" fee, which usually starts at around $20. You are permitted to bring up to two additional bags for the under-bus compartment, but each extra bag incurs a significant fee. The carry-on bag you bring inside the bus must fit in the overhead rack or under the seat in front of you; typical dimensions for this are roughly 15 x 12 x 7 inches. Greyhound is strict about these limits in 2026 because the storage space under the bus is shared with commercial freight (Greyhound Package Express). It is highly recommended to weigh your bag at home, as the scales at the terminal are calibrated and agents will not hesitate to charge for even a few extra pounds.
