Here's a more detailed breakdown:
* The nail plate: This is the visible part of the nail, and its thickness can range from 0.3 to 0.8 millimeters.
* The nail matrix: This is the hidden part of the nail where growth occurs. It's thicker than the nail plate, around 1 to 2 millimeters.
* The nail bed: This is the skin beneath the nail plate, and it's about 0.5 millimeters thick.
Keep in mind that these are just averages. Your fingernail thickness may differ significantly from these values.
