The summit of a mountain or hill may be measured in three principal ways:
The topographic elevation of a summit measures the height of the summit above a geodetic sea level.[2] The first table below ranks the 40 highest major summits of Greenland by elevation.
The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.[2][3] The second table below ranks the 40 most prominent summits of Greenland.
The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.[4] The third table below ranks the 40 most isolated major summits of Greenland.

Of the most isolated major summits of Greenland, only Gunnbjørn Fjeld exceeds 3000 kilometers (1864 miles) of topographic isolation. Four peaks exceed 500 kilometers (310.7 miles) of topographic isolation, 13 peaks exceed 200 kilometers (124.3 miles), and 21 peaks exceed 100 kilometers (62.14 miles) of topographic isolation.

^This article defines a significant summit as a summit with at least 100 meters (328.1 feet) of topographic prominence, and a major summit as a summit with at least 500 meters (1640 feet) of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least 1500 meters (4921 feet) of topographic prominence.
