It commands wide views stretching west to north-east, which is rarely accidental in monuments of this type. The scale is modest but deliberate: the enclosing bank measures roughly 19 metres across at its widest, with a flat interior space about 5.8 metres north to south and 5.6 metres east to west.

A ring-cairn is a prehistoric funerary or ceremonial monument defined by a roughly circular or oval bank of piled stone and earth, with a clear interior space that was not itself covered by the mound. This distinguishes it from a simple cairn, where stones accumulate over a central point. At Ballyganner, the bank is uneven rather than neatly symmetrical, and there are noticeable deposits of additional cairn material on the exterior at the east and west sides, giving the structure a slightly irregular profile. The monument sits within a large, multiperiod field system, meaning the surrounding landscape has been divided and worked across several different eras, leaving the cairn embedded in layers of agricultural history rather than standing in isolation from it.
