Very small coil springs - often called micro springs - are commonly found in a diverse array of pocket-sized devices and tools. Wire diameters for everyday use at this scale typically start from as little as 0.25mm, with an overall outer diameter of a micro compression spring measuring somewhere in the region of 2-3mm. However, for more specialised uses and devices, small springs can be made considerably thinner even than this.
