Leash Size by Board Length
| Board | Leash Length | Thickness | Notes |
|---|---|---|---|
| Shortboard (5'6"–6'6") | 6 foot | 5/16" (regular) | Standard shortboard leash |
| Funboard / Mini Mal (7'–8') | 7–8 foot | 1/4"–5/16" | Match leash to board length |
| Longboard (9'–10'+) | 9–10 foot | 3/16" (comp) or 1/4" | Longboard leashes are thinner for less drag |
| Big wave (gun) | 10–12 foot | 3/8" (big wave) | Extra thick for strong hold in heavy surf |
Types of Surf Leashes
Standard leash for most conditions. Moderate thickness and length matching your board.
Thinner and lighter for performance surfing. Less drag in the water but less durable.
Extra thick (3/8"+) and long. Designed for heavy surf where a regular leash could snap.
Longer (9-10 feet) with a coiled section to prevent drag while cross-stepping.
How to Attach a Surf Leash
- 1Thread the leash cord through the leash plug on the tail of your board
- 2Loop it through itself and pull tight so it cannot slip out
- 3Wrap the velcro cuff around your back ankle — snug but not cutting off circulation
- 4Tuck the excess velcro tab into itself so it does not peel open in the water

Frequently Asked Questions
What length leash do I need?
Match leash length to board length. A 6-foot board gets a ~6-foot leash. A 9-foot longboard gets a 9-foot leash.
Which ankle does the leash go on?
Your back foot ankle — closest to the tail. Regular footers (left foot forward) attach to the right ankle; goofy footers (right foot forward) to the left.
Do I need a leash?
Yes. A leash is a safety device. Without one, your board becomes a missile that can injure other surfers. Most beaches and surf schools require them.
How long does a surf leash last?
A good leash lasts 1-3 years depending on usage and care. Rinse with fresh water after every session. Replace when you notice swivels seizing, velcro weakening, or the cord developing stress marks.
