Golf Tools & Calculators
Free, practical calculators for rooftop and urban golf — dial in your club distances, estimate ball flight, size a safe practice net, track your handicap, read green speed, and budget your range time.
Club Distance & Gapping Calculator
Turn your real carry distances into a gapping chart — every club sorted by distance with the gap to the next, flagging big gaps that need a club and overlaps where two clubs do the same job
Ball Carry Calculator
Estimate carry, apex height, and hang time from ball speed and launch angle using projectile physics — a clean way to see how the two numbers leaving the clubface shape the flight
Rooftop Net Height Calculator
Size a practice net safely — enter the distance to the net and the steepest launch you might hit, and get a conservative minimum net height for rooftop, balcony, garage, or backyard practice
Golf Handicap Calculator
Estimate your Handicap Index under the World Handicap System — enter recent rounds with their Course and Slope Ratings and see the score differentials and index from your best scores
Stimpmeter Green-Speed Converter
Turn a Stimpmeter reading into a plain-language speed category and see how far a putt rolls uphill versus downhill on a slope you choose — the physics behind reading a breaking putt
Driving-Range Cost Calculator
See what range practice really costs per ball, session, month, and year, and compare pay-as-you-go buckets against a monthly membership to find your break-even point
