Always measure horizontal distance from the board face, not the wall. Confirm local league rules for specialty formats.
Mount first, then measure. Cabinet depth changes where the board face sits.
Use the tool, then practice the result
This tool runs entirely in your browser and requires no account. Use consistent rules and honest inputs so its output remains useful over time. Pair it with a regulation setup and one focused training goal rather than changing several parts of your game at once.
Keep the board format in mind
Steel-tip, soft-tip and specialty dart formats can use different distances, equipment and finishing rules. Confirm the format before treating any measurement or route as universal. Tournament and league rules should take priority when you are preparing for organized play.
