This is according to the cadastral survey and estimated land areas certified and provided to the Department of Budget and Management by the Land Management Bureau, Department of Environment and Natural Resources, as of December 2013.
Nearly half or 43% consists of mainland Luzon and the islands of Mimaropa, 40% Mindanao, and 17% the Visayas island group (Western, Central, and Eastern Visayas, and Negros Island).
Among the proposed federated regions, the Autonomous Region in Muslim Mindanao (ARMM) will be the largest in terms of land area at 36,650.95 sq km or 12.2% of the country’s total land area, while the National Capital Region is the smallest at 619.54 sq km (0.21%).
By province, Palawan is the largest in terms of land area at 17,030.75 sq km, followed by Lanao del Sur, 15,055.51 sq km; Isabela, 13,102.05 sq km; Bukidnon, 10,498.59 sq km; and Agusan del Sur at 9,989.52 sq km.

Under the proposed federal system, Calabarzon will be the largest federated region in terms of population, with 14 million people (14.3% of total population), while the Cordillera Administrative Region (CAR) will be the smallest with 1.7 million (1.71%).
