Frequently asked questions
How big should a Longsword cosplay prop be?
The canonical Longsword overall length is 110 cm (3'7"), based on Average adult at 178 cm (5'10"). For a cosplayer who is 165 cm, proportional scaling brings the overall length to about 102 cm. Use the calculator above to get exact dimensions for your height.
What material should I use for a Longsword cosplay?
At 110 cm canonical length, the Longsword is a large prop. EVA foam is the best choice for builds this size. It keeps the weight under 2.5 kg, is convention-safe, and shapes easily with a heat gun. Use a PVC pipe or wooden dowel core for rigidity, and seal with Plasti Dip or contact cement before painting.
