Understanding that the correct length for a badminton net is 6.1m Why do several manufacturers also produce 7.3m length nets? I came across this when my local school purchased nets of the 7.3m length and found them all bunched up when setup correctly with the posts 6.1m apart, they tried setting up with the posts incorrectly 7.3m apart which completely threw everyone and obviously wrong, finally they replaced with the correct 6.1m length net and solved the issue. Several weeks later my local sports facility also purchased new nets 7.3m long! Again I watched in dismay to see the brand new nets all bunched up and wrong between the correct post separation of 6.1m Again they will replace with correct 6.1m nets. I cant think of any training scenario or post setup that would gain from this length of net and I cant think of any shared sport that has a net length similar. Have I found a true anomaly that just got a foothold and manufacturers just kept copying?
