The most important consideration when buying a surfboard is surfboard sizing. Getting a board that is too small will lead to frustration as you struggle to catch waves and generate speed. Going too large will feel bulky and hard to turn.
That said, a blanket measurement that assumes every surfer has an identical build is inane.
I don’t know how many surfboard manufacturers recommend riding a surfboard model “XX Inches Shorter Than You Are Tall” and how many ill informed surfers have purchased a surfboard that is too big or too small for them as a result of following this recommendation but there are too many. Even Channel Islands, the largest surfboard manufacturer in the world, uses this system for some models. CI, you should know better!
This is one of the more nonsensical, outdated systems I have heard of.
Take two surfers, both 6’0 tall. One weighs 80KG’s (160 pounds). The other weighs 105KG’s (230 pounds). Per the wisdom of the “XX Inches Shorter…” guidance, both surfers should ride the same size board. Does that make sense?
This overly simple methodology also does not take into account experience, age, fitness, skill level, riding style, etc. Just height, only height. Duh.
Fortunately, the better informed surfing contingent have wised up to the fact that volume is what matters most. Read Know Your Volume, Catch More Waves for more on finding your volume sweet spot and forget the nonsensical “XX Inches Shorter Than You Are Tall” rule. For all but one very specific body type, it does not work!
