General term for boundary or border between areas. Can be used for property lines, national borders, or abstract boundaries.

Limit or boundary, often emphasizing the maximum extent or a point beyond which something cannot go.

範囲 (はんい) is the most versatile for 'bounds' in the sense of scope or extent. 限界 (げんかい) emphasizes a hard limit or breaking point. 境界 (きょうかい) is specifically a border or dividing line between two areas.
