F Hook in Crochet

F hook in crochet measures 3.75mm, smaller than the common H hook at 5.0mm, typically used with sport or DK weight yarn for a tighter, denser fabric than worsted weight projects. I reach for an F hook for amigurumi specifically, where a tighter gauge hides stuffing better. This guide gives the direct size.
