A 72-yard approach can be harder to choose than a full seven-iron. You know which club reaches the green from 160, but the shorter shot sits between two familiar swings. A wedge distance matrix turns that uncertainty into a small set of measured options. Instead of borrowing another golfer’s yardages, you record how far your own wedges carry with a few repeatable swing lengths. The result is a practical reference for the next time you face a partial approach. Here is the plan: collect six combinations in one focused session, record carry and contact, then keep only the shots you can repeat. Track it before you trust it.
PGA Coach Joanna Coe teaches the value of combining different wedges and swing lengths to cover distances below a full swing. This guide builds a simple measurement process around that idea. It does not prescribe exact distances or promise that a matrix will lower your scores. Your numbers depend on contact, club loft, ball, turf, weather, and how you swing on the day.
What a wedge distance matrix records
The matrix has clubs on one side and comfortable swing lengths on the other. For example, you might list pitching wedge, gap wedge, and sand wedge, then test a short, medium, and full motion with each. Each cell contains your observed carry distance, not the number stamped on a club or a distance you once hit with a tailwind. Carry is where the ball first lands. Total distance adds roll, which changes with green firmness, slope, and spin.
Start with a narrow grid. Three clubs times two partial swing lengths gives six combinations. You can add more later if those six become dependable. A giant chart of every imagined yardage looks impressive but is hard to use when the strike is inconsistent. The aim is a small collection of shots you can recognize under normal course pressure.
Write down how you define each swing length. “Half swing” means different things to different players. A better cue is something you can repeat, such as hands reaching a point around waist height or lead arm reaching a comfortable chest-height position. These are personal reference points, not universal mechanics. If you work with a coach, use the cues already in your lesson plan.
Choose a safe place to measure carry
Use a practice facility with clearly marked targets or a launch monitor you trust. Check whether the range uses limited-flight balls. If it does, its yardages may not transfer cleanly to your usual course ball. Ask the facility about its setup, and record the ball type in your notes. You can still use the range to compare one swing to another, but treat the absolute number cautiously until you verify it on grass or with your normal ball.
A laser rangefinder can identify a target distance, but it does not by itself tell you exactly where every ball first landed. Watch the landing area carefully, use a launch monitor’s carry reading when available, or set up a supervised on-course practice session where the facility permits it. Do not hit extra balls during a normal round in a way that delays play or violates event conditions. Choose a measurement setting designed for practice.
PGA coaching on target-based practice emphasizes specific yardages. For this project, make each target a measuring point rather than a test of whether you can hit a flag. A consistent start line and a useful carry number matter more than one spectacular shot that is far outside your normal pattern.
Use a repeatable test sequence
Warm up with easy wedges before recording anything. Then choose the first club and first swing cue. Hit five to eight balls while aiming at the same general target. Note each carry distance you can measure. Move to the next swing length only after you finish the set. Rotating through all clubs after every ball makes the first session harder to interpret because you are changing club and motion at once.
Keep obvious mishits in the record, but label them. If a heavy strike carries 30 yards when the other six reach about 60, it tells you something about reliability. You may calculate a typical carry from the solid strikes for the matrix, yet the mishit rate belongs in the margin. A carry number without any sense of dispersion can create false confidence. On the course, a 65-yard shot that often finishes 15 yards short needs a larger safe target than the clean average suggests.
Write the environment beside the numbers: date, temperature, wind direction, ball, surface, and whether you used a range mat. You do not need a weather station. A note such as “calm morning, mat, range balls” is enough to explain why another session might differ. The matrix is a decision aid, not a laboratory certificate.
A 35-minute wedge distance matrix session
This is a session sheet you can run with a short practice window. Put one variable at a time on the page. Do not change club and swing cue in the same six-ball set. Write the numbers you actually see, including the misses. The goal is a usable baseline, not a perfect grid on day one.
- Minutes 0–5: warm up. Hit easy wedges without logging distance. Choose a calm target and note the ball and surface you are using.
- Minutes 5–10: define two swing cues. Write a short cue and a medium cue in words you can repeat. Make a few rehearsals with each before measuring.
- Minutes 10–25: collect six-ball sets. Hit six balls with one club and cue, record each carry and contact, then switch only one variable. Work through the combinations you use most often.
- Minutes 25–30: check a different target. Pick a yardage that should match one reliable cell. Hit six more balls and count how many land in a sensible zone around it.
- Minutes 30–35: make a pocket card. Write only the combinations with repeatable contact. Note the common short or long miss beside each. Leave the uncertain cells blank for next week.
Use a simple line for each set: “gap wedge / medium cue / six carries / clean-contact count / usual miss.” If the same cue produces a wide spread, the matrix should say “uncertain” instead of publishing a precise-looking average. Next session, repeat that one cell before adding new ones.
Turn your wedge distance matrix into a usable chart
For each combination, write a rounded typical carry and a simple confidence label. An example might read “gap wedge, medium swing: about 72 yards, reliable” or “sand wedge, short swing: about 38 yards, mixed contact.” These are example formats, not recommended yardages. If two combinations produce almost the same carry, keep the one you strike more consistently and leave the other off your pocket card.
A small table can fit in a phone note: club, swing cue, typical carry, common miss. The common miss is often as useful as the carry. “Usually short when tempo quickens” may remind you to choose a center-green target rather than a tight flag. If you use a GPS device or rangefinder, keep the chart close to your normal pre-shot tools so it gets used instead of forgotten.
Do not treat every distance as a direct flag attack. First identify the safe landing area. Then see whether one of your measured combinations fits that area. If 72 yards reaches a back pin but leaves water behind, a shorter safe carry might be the better plan. The chart helps you choose a known shot; course strategy determines where that shot should land.
Check the gaps between your wedges
A wedge distance matrix may reveal that two clubs cover the same range or that a particular distance has no comfortable option. That does not immediately mean you need a new wedge. First check whether the data came from reliable strikes and comparable balls. Then see whether a modest swing-length adjustment with a familiar club covers the gap. PGA Coach Joanna Coe’s wedge-distance demonstration shows why club choice and swing length work together.
If a gap persists and you are considering equipment changes, a professional fitting can measure actual lofts and gapping. Marketing labels such as “gap wedge” do not guarantee a particular carry for your swing. The matrix gives you evidence to bring to that conversation rather than a guess based on a single shot.
Make room for a low, running option as well as lofted shots if the course conditions call for it. That shot may roll much farther, so it needs its own note rather than being forced into a carry-only cell. Keep the main chart simple; add a separate line for a practiced rollout option.
Recheck your wedge distance matrix on the course
During the next few rounds, note only a handful of wedge approaches: estimated distance, chosen club and swing cue, where the ball first landed, and whether contact was clean. Do not rewrite the chart after one windy shot. Look for a repeated difference across several comparable attempts. A ball landing short because of a heavy strike is a contact observation; a series of solid shots landing short in calm conditions may call for a carry-number update.
PGA Coach Mike Mendoza suggests wedge games on the range as a way to learn distance and feel. You can make your own version by choosing one target and alternating between two charted combinations that should reach it. Score whether each ball lands in a reasonable zone. That tests the usefulness of the chart without requiring perfect precision.
Review the matrix every few weeks, or whenever your swing, wedges, ball, or usual course changes materially. If you have only one short practice window, test the combinations you actually face most often. A small accurate chart beats a large stale one.
A simple first-session checklist
Bring your normal wedges and a note card. Pick two comfortable partial swings and one clear target area. Warm up, test five to eight balls per combination, record carry and mishits, and label the conditions. Round the reliable numbers into a pocket chart. On the course, use the chart to select a familiar shot toward a safe landing zone, then collect a few real-round observations before revising it.
Your first wedge distance matrix will probably have blanks. Leave them blank. The purpose is to replace a vague 70-yard guess with a measured option you can repeat, then improve that option over time. It is a working document for your game, not a claim that every partial swing will travel the same distance.
