Score

The three measures
- Polsby-Popper
- 0.17at least as compact as 26% of districts on this measure
Area compared with perimeter. Low for jagged or snaking edges.
- Reock
- 0.47at least as compact as 45% of districts on this measure
Area compared with the smallest circle around the district, counting only land. Low for stretched shapes.
- Convex hull
- 0.66at least as compact as 19% of districts on this measure
Area compared with a rubber band stretched around the district, counting only land. Low for bites and tentacles.
Each measure runs from 0 to 1, where 1 is a perfect circle or a shape with no dents.
The state's edge
10% of this district's border is the state's edge: a coastline, a national border or a state line. Mapmakers don't choose those lines. A ragged one, like a coastline or a river, lowers Polsby-Popper. Reock and convex hull count only the state's own land, so water and neighboring states don't count against them. More on the state's edge
