Dartboards vs. Golf Cup
Comparing 2 standards across 16 specifications. 16 key differences identified.
Official dartboard specifications are standardized by the World Darts Federation (WDF) and the Professional Darts Corporation (PDC). A regulation bristle dartboard has an outer diameter of 17.75 in (45.1 cm), divided into 20 radial segments. The center bullseye is mounted at exactly 5 ft 8 in (1.727 m) above the floor, with the throwing line (the oche) positioned at a horizontal distance of 7 ft 9¼ in (2.369 m) from the face of the board (9 ft 7⅜ in diagonal).
Official golf hole dimensions are governed by the USGA and The R&A (Rules of Golf Rule 1.1 / Equipment Rules Appendix IV). A regulation golf hole must have a diameter of exactly 4.25 in (108.0 mm) and a minimum depth of 4.0 in (101.6 mm). If a cup liner is inserted, the outer diameter of the liner must not exceed 4.25 in, and its top lip must be sunken at least 1.0 in (25.4 mm) below the green putting surface.
