wedge-distance-calc

Golf wedge distance calculator based on real-world swing speed data. Estimates carry and total distance for all 5 wedge types (PW, GW, SW, LW, 60-degree) given a clubhead speed. Includes a gapping chart feature for full, 3/4, and 1/2 swing distances.

Installation

Python

pip install wedge-distance-calc

JavaScript / Node.js

npm install wedge-distance-calc

Usage

Python

from wedge_distance_calc import estimate_distance, get_all_distances, get_gapping_chart

# Single wedge estimate
result = estimate_distance("PW", 85)
print(result)
# {
#   'wedge': 'PW',
#   'loft': 46,
#   'swing_speed': 85.0,
#   'carry_yards': 117.5,
#   'total_yards': 126.9
# }

# All wedges at a given speed
all_wedges = get_all_distances(85)
for wedge, data in all_wedges.items():
    print(f"{wedge}: {data['carry_yards']} carry / {data['total_yards']} total")

# Full gapping chart (full / 3/4 / 1/2 swings)
chart = get_gapping_chart(85)
for wedge, swings in chart.items():
    for swing_type, data in swings.items():
        print(f"{wedge} {swing_type}: {data['carry_yards']} yards")

Example output for get_all_distances(85):

PW: 117.5 carry / 126.9 total
GW: 107.5 carry / 116.1 total
SW:  95.0 carry / 102.6 total
LW:  81.0 carry /  87.5 total
60:  75.0 carry /  81.0 total

JavaScript

const { estimateDistance, getAllDistances, getGappingChart } = require('wedge-distance-calc');

// Single wedge estimate
const result = estimateDistance('PW', 85);
console.log(result);
// {
//   wedge: 'PW',
//   loft: 46,
//   swingSpeed: 85,
//   carryYards: 117.5,
//   totalYards: 126.9
// }

// All wedges at a given speed
const all = getAllDistances(85);
for (const [wedge, data] of Object.entries(all)) {
  console.log(`${wedge}: ${data.carryYards} carry / ${data.totalYards} total`);
}

// Full gapping chart
const chart = getGappingChart(85);
for (const [wedge, swings] of Object.entries(chart)) {
  for (const [swingType, data] of Object.entries(swings)) {
    console.log(`${wedge} ${swingType}: ${data.carryYards} yards`);
  }
}

Supported Wedges

| Wedge | Code | Loft | |-------|------|------| | Pitching Wedge | PW | 46° | | Gap Wedge | GW | 50° | | Sand Wedge | SW | 54° | | Lob Wedge | LW | 58° | | 60-Degree | 60 | 60° |

Methodology

Distances are calculated using linear interpolation between established data points at 60 mph and 110 mph clubhead speed. Total distance adds approximately 8% for roll. The gapping chart multiplies swing speed by 85% (3/4 swing) and 65% (1/2 swing) to estimate partial-swing distances.
