Lure size, and what it is selecting
Explainer · Last reviewed 2026-08-14
Size decides which fish can take the lure, how far away it can be detected, and how much of the water column it can be worked through. Those three are frequently in conflict.
LURE SIZE IS DOING THREE JOBS AT ONCE and they do not point the same way.
IT SELECTS THE FISH. A lure a fish cannot get in its mouth will produce follows and knocks and no hook-ups. Increasing size is the standard response to small fish attacking a lure intended for larger ones, and it works. What it does not do is exclude small fish absolutely — small predators attack objects far larger than they can swallow, and that is where most missed takes on big lures come from.
IT SETS THE DETECTION RANGE. A larger lure displaces more water, presents a bigger silhouette and is visible and detectable further away. In coloured water and at depth this is the dominant consideration, and it is why the standard answer to poor visibility is a bigger, stronger-actioned lure rather than a brighter one.
IT CONSTRAINS THE TACKLE AND THE PRESENTATION. A large lure needs a rod that will cast it and hooks that will hold, it lands heavily, it cannot be fished slowly without sinking, and it is tiring to work all day. A small lure can be fished on fine tackle, lands softly and can be worked slowly — and cannot be cast into wind or fished deep in current.
HOW THE DECISION IS ACTUALLY MADE. Start from the prey size the fish are feeding on, then adjust for two things. UP, if you want to sort for larger fish, if visibility is poor, or if you need to cast further or fish deeper. DOWN, if fish are following and refusing, if the water is very clear, if the fish are inactive, or if the prevailing natural food is small.
THE FOLLOW-AND-REFUSE SIGNAL IS THE MOST USEFUL FEEDBACK IN LURE FISHING and it usually means one of three things: the lure is too large, the retrieve is too slow so the fish has time to inspect, or the fish has seen this before. All three corrections are available immediately, and the size one is the cheapest to test.
AND THE HOOK CHAIN. Larger lures carry larger hooks, which need more force to set and do more damage to a fish that is not the intended quarry. That makes size a welfare decision as well as a selectivity one, and it is the reason 'go bigger until something works' is a worse strategy than it sounds.
