New Britain extends from 148°18′28″ to 152°24′15″ E longitude and from 4°08′00″ to 6°18′57″ S latitude. It is crescent-shaped, approximately {{cvt|520|km|mi}} along its southeastern coastline, and from {{cvt|29|to|146|km}} wide, not including a small central peninsula. The air-line distance from west to east is {{cvt|477|km|mi}}. The island is the [[List of islands by area|38th largest in the world]], with an area of {{cvt|35140|km2|sqmi}}.

Steep cliffs form some sections of the coastline; in others the mountains are further inland, and the coastal area is flat and bordered by coral reefs. The highest point, at {{convert|2334|m|ft}}, is the [[stratovolcano]] [[Mount Ulawun]] in the east.<ref>{{cite web |title=Melanesia |url=https://www.peakbagger.com/range.aspx?rid=75 |website=Peakbagger |access-date=25 March 2020 |archive-date=20 October 2020 |archive-url=https://web.archive.org/web/20201020215132/https://www.peakbagger.com/range.aspx?rid=75 |url-status=live }}</ref><ref>{{cite web |title=Ulawun Volcano |url=https://www.volcanodiscovery.com/ulawun.html |website=Volcano Discovery |access-date=25 March 2020 |archive-date=10 June 2020 |archive-url=https://web.archive.org/web/20200610053134/https://www.volcanodiscovery.com/ulawun.html |url-status=live }}</ref>  Most of the terrain is covered with tropical rainforest, and several large rivers are fed by the high rainfall.

The Nakanai Range in East New Britain is composed largely of limestone [[karst]], which extends from the mountain peaks to the southern coast.  Erosion of the porous limestone has created large sinkholes, or dolines, and extensive caves and river cave systems.  The Nakanai Caves, together with two other [[karst]] regions on the New Guinea mainland, were nominated to the [[World Heritage Tentative List]] in 2007 as The Sublime Karsts of Papua New Guinea.<ref>Gabriel, J., Specht, J., Leavesley, M., Kelly, M., Wood, M., Foale, S., Filer, C., McIntyre-Tamwoy, S., Bourke, R.
