Plain terms for a small site. Use the calculator and the catalog freely for your own surfing; don't copy the catalog wholesale.
The volume SurfCalc suggests is a starting point drawn from published industry sizing and real-rider data, with a stated ±5% working range. It is not a guarantee that a board will suit you. Board choice depends on things no calculator sees: your waves, your style, the particular shape. Demo a board when you can and trust your own experience over any number, including ours.
Prices, stock, dimensions and photos come from each store's own public feed and are refreshed nightly, so they can be out of date or wrong. Litres marked ≈ are SurfCalc's estimates, not the maker's figure, and the method and typical error are shown on hover. The store's own page is the authority on what it sells and for how much. Purchases are between you and the store; SurfCalc is not a party to them.
You may use the site, link to any page, and share results. You may not scrape, download or republish the catalog in bulk, resell it, or build a competing dataset from it. The compilation, its normalised dimensions and volume estimates, the model, the text and the design are © SurfCalc. Store product names and photos remain the property of their owners.
Some store links carry a referral code and may earn SurfCalc a commission. This is described in the Privacy page and never changes what is shown or how it is ordered.
The site is provided as is. SurfCalc is not liable for any loss arising from reliance on a volume figure, a listing, or a link. Nothing here limits rights you have under law that cannot be limited.
These terms may change as the site grows; the date below moves when they do.
