Bolt Circle Diameter is the diameter of the circle formed by the centers of the chainring fixing bolts. With 4-bolt cranksets, this is easy to measure. 5-bolt cranks are more difficult.
If you are unsure about what size chainring you need, Wolf Tooth Components has an excellent guide to measuring your rings.
