## Colour key

| Class | Prominence |
| Marilyns | 150 – 599 m |

The table is colour-coded based on the classification or "listing" of the hill. The types that occur in East Sussex are Marilyns, HuMPs and TuMPs, listings based on topographical prominence. "Prominence" correlates strongly with the subjective significance of a summit. Peaks with low prominences are either subsidiary tops of a higher summit or relatively insignificant independent summits. Peaks with high prominences tend to be the highest points around and likely to have extraordinary views. A Marilyn is a hill with a prominence of at least 150 metres or about 500 feet. A "HuMP" (the acronym comes from "Hundred Metre Prominence) is a hill with a prominence of at least 100 but less than 150 metres.
In this table Marilyns are in beige and HuMPs in lilac. A "TuMP" as defined here is a hill with a prominence of at least 30 but less than 100 metres. The term "sub-Marilyn" or "sub-HuMP" is used, e.g. in the online Database of British and Irish Hills to indicate hills that fall just below the threshold. To qualify for inclusion, hills must either be 200 metres or higher with a prominence of at least 30 metres, below 200 metres with a prominence of at least 90 metres (the threshold for a sub-HuMP) or be in some other way notable. For further information see the Lists of mountains and hills in the British Isles and the individual articles on Marilyns, HuMPs, and TuMPs. By way of contrast, see also the article listing Tumps (a traditional term meaning a hillock, mound, barrow or tumulus).
