haakmaat

Haakmaat is the size designation used for fishing hooks in Dutch angling terminology. It refers to how large or small a hook is and is linked to the hook’s physical dimensions, such as the gape (the opening) and the shank length. The size system is not standardized across manufacturers, and two common conventions exist: a numbered scale (for example 1, 2, 4, 6) and a large-quantity scale using numbers with a slash (such as 1/0, 2/0). In many brands, lower numbers indicate larger hooks, while the 0-series increases in size with more zeros, though there are exceptions. Because of brand variation, direct size comparisons between products often require checking the manufacturer’s specifications.

Selection of haakmaat depends on several factors. Target species, bait presentation, fishing technique, and line strength all influence the choice. Small hooks are used for delicate baits and small fish, while larger hooks suit bigger bait and larger species. The hook type (for example J-hook, circle, or treble) and the fishing method (bait fishing, lure fishing, or fly fishing) also interact with the appropriate size. Anglers consider the fish’s mouth size and feeding behavior, as well as water conditions and depth.

Context:

In Dutch-speaking regions, haakmaat is a common term in shops, catalogs, and guides for both freshwater and coastal fishing. Because brands vary, many guides recommend comparing the actual measured gape and shank dimensions rather than relying solely on the printed size.
