The lightsabers built at Savi's Workshop in Disney World (Galaxy's Edge) are roughly 41 to 44 inches long in total. The removable blade is a standard 31-inch (79cm) plastic tube that is illuminated by LEDs, while the heavy metal hilt adds another 10 to 13 inches depending on the specific "Scrap Metal" pieces you choose to build your custom saber. For comparison, the "Legacy Lightsabers" sold in Dok-Ondar's Den of Antiquities come in different blade lengths, typically 26 inches or 31 inches, to better suit younger Jedi or those who prefer a specific character's proportions. Because of their length, Disney provides a padded carrying case that measures approximately 50 inches to protect the saber during travel. If you are flying in 2026, most major airlines—including Delta and United—treat these as a personal item or an "exceptional" carry-on, allowing you to store them in the overhead bin alongside your regular luggage as long as you are careful not to let them be crushed by heavier bags.
