Golf tools

Free golf calculators. The distance ones use the same carry model as our course forecasts, so the numbers account for altitude and temperature.

• Golf club distance calculator

  Carry and total yardages for every club in your bag, from your swing speed or ball speed.

• Golf swing speed calculator

  Work out your driver swing speed from how far you hit it, with the shaft flex that usually fits.

• Golf altitude distance calculator

  How much farther, or shorter, your shots fly at a course higher or lower than the one you know.

• Golf handicap index calculator

  Your Handicap Index from your scores and each course's rating and slope, the World Handicap System way.

• Golf course handicap calculator

  How many strokes your Handicap Index gives you on a course and tees, and on which holes.

• Why your ball flew farther today

  Slide the temperature, altitude and humidity and watch what the air does to your carry.
