your life line
…that vital, genius piece of equipment that always keeps you connected to your board.
length and and thickness are the main factors to consider.
As a general rule your leash should be about 6″ longer than your board. So naturally, the longer the surfboard is, the longer the leash required. If your board is 7’0 then a 7’6 leash is good.
Thickness varies from 5mm to 7.5mm. The thickness of a legrope is dependent on the size of your surfboard and the size of the waves you like to surf. Basically long boards and heavier boards require the added strength of a thicker legrope and if you surf big waves a thicker leash is also required. Advanced surfers prefer thinner legropes to reduce the resistance of drag in the water so they can retain speed.
The railsaver is the velcro section that links the small rope cord to the leash. It’s thickness protects the edges (rails) of your surfboard from being damaged if stress or pressure is applied. The rail saver is in its correct position if it makes contact with the rails when your leash is stretched out fully. If the string is touching the rails when it is stretched out then you need to shorten the string. See the video below.

swivels allow any tangles to automatically untangle themselves and prevent your leash from getting tangled up and wrapped around your feet. Choosing a leash with a double swivel system is the best. One swivel is attached to the ankle strap and the other at the rail saver.
