Frequently asked questions
How big should a Greatsword cosplay prop be?
The canonical Greatsword overall length is 150 cm (4'11"), based on Average adult at 178 cm (5'10"). For a cosplayer who is 165 cm, proportional scaling brings the overall length to about 139 cm. Use the calculator above to get exact dimensions for your height.
What material should I use for a Greatsword cosplay?
At 150 cm canonical length, the Greatsword 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.
