The length of a manja (kite string) reel depends on the type and size you purchase, as there is no fixed standard for all manja reels.
For example:
Small reel: 500 to 800 meters
Medium reel: 1,000 to 2,000 meters
Large reel: 3,000 to 5,000 meters or more
A roll of manja typically contains approximately 900 meters of yarn. While some manufacturers can produce it in lengths of 1,000 meters, waste during the coating process can result in a final length of between 850 and 950 meters per roll.
