Geographically located in the Lower North on the bank of the Ping River, Kamphaeng Phet is 358 kilometres from Bangkok. To its East are riverine flatlands while the western areas are made up of high mountains lush with fertile forests where a number of national parks have been established.
 
Areas along the river bank at present-day Mueang district used to host several ancient towns which had played a major role as strategic front-line frontiers since Sukhothai was the kingdom's capital down through the times of Ayutthaya and early Rattanakosin (Bangkok) eras. In fact, the name Kamphaeng Phet actually means as strong as walls or forts make of diamonds.

Kamphaeng Phet covers an area of 8,607 square kilometres. It is divided administratively into 9 districts, namely, Mueang Kampheang Phet, Phran Kratai, Khlong Khlung, Khanu Woralaksauri, Sai Ngam, Lan Krabue, Khlong Lan, Sai Thong Watthana and Pang Sila Thong and 2 sub-districts, Bueng Samakkhi and Kosamphi Nakhon.
