A pothole has to be at least 40mm in depth to be considered a pothole
If it's less than four centimetres deep, it's not a pothole. It's, erm, a potholelet, maybe. Please note that not all cavities deeper than 40mm are necessarily potholes, however. The Channel Tunnel, for example, is rather deeper, but does not require filling with tarmac by a sweaty man in a high-vis jacket.
