According to estimates, the site of the Peinan artifacts has a total area of more than 80 hectares, with the richest area comprising about 30 hectares. For ten years archaeologists have painstakingly excavated ten thousand square meters, which is still but a small portion of the total area. The rest is still buried beneath what is today called Peinan Culture Park.
據估計，卑南遺址的總面積至少有八十多公頃，精華地段三十公頃左右，考古學家十年間搶救開挖的一萬多平方公尺，只是其中一小部份，其它部份都還完好埋藏在今天文化公園的地下。
