Here's a more precise breakdown:
* Length: Elvers can range in length from 2.5 to 7.5 cm (1 to 3 inches), but they are typically around 3 cm (1 inch) long.
* Weight: They are extremely lightweight, weighing only a few grams.
It's important to note that the size of an elver can vary depending on the species and stage of development. But they are always incredibly small and delicate creatures.
