That slim, reflective training aid in your bag is one of the most powerful tools you can own for building a consistent, pressure-proof putting stroke. If you’ve been frustrated by pushed and pulled putts, you’re in the right place. This guide will walk you through exactly how to use a golf putting mirror to diagnose your setup, correct your alignment, and groove a pure stroke path, turning frustrating misses into confident makes.
What a Putting Mirror REALLY Does For Your Game
At its heart, a putting mirror is an honesty machine. Golf is a game of tiny margins, and what feels straight often isn't. The mirror cuts through feel and provides instant, accurate visual feedback on the non-negotiable fundamentals of great putting. You can’t argue with a reflection.
It helps you self-correct three primary areas:
- Eye Position: Where your eyes are in relation to the ball dramatically affects how you perceive the target line. The mirror shows you precisely where you're looking from.
- Shoulder and Putter Face Alignment: More putts are missed before the stroke ever starts due to poor alignment. The various lines on the mirror help you ensure your body and club face are perfectly square to your intended start line.
- Stroke Path: While some great putters use a slight arc and others are more "straight back, straight through," the mirror’s path lines give you a visual guide to keep your stroke on plane and prevent wobbles, pushes, or pulls.
Using one isn't about finding a quick fix for a single round. It's about auditing your mechanics and building a repeatable, reliable setup and stroke you can trust, especially when the 4-footer actually means something.
Getting Started: Your First Session with the Putting Mirror
Before diving into complex drills, the first step is just to get comfortable and establish your baseline. You can do this on a practice green or, just as effectively, at home on a carpet or putting mat.
Here’s your simple setup process:
- Find a Straight Putt: On the green, find a relatively straight, flat putt of about 5-8 feet. At home, just aim for a spot on the wall or a makeshift cup. The goal here is alignment, not reading a break.
- Set Up the Mirror: Place the putting mirror on the ground and put a golf ball in the designated ball-gate or cutout.
- Aim the Mirror: Most mirrors have a bold centerline. Aim this entire line directly at the center of your target. A handy trick is to place a tee in the ground a few feet in front of the mirror, right on the target line, to give you a more immediate aiming point.
- Take Your Stance: Now, without trying to change anything, simply step in and address the ball as you normally would. This first look is your diagnostic test. See what your natural tendencies are before you try to fix them.
The Three Fundamental Checks: Eye, Shoulder, and Face Alignment
Once you're set up, you'll perform three simple, static checks. This initial alignment is where most amateur golfers can make the biggest, fastest improvements.
Check #1: Eye Position – The Foundation of Perception
Your eye position is the foundation of your putting reality. If your eyes are too far inside the ball, the hole will appear further right than it is, often causing a pull. If your eyes are outside the ball, you'll tend to see the line to the left, likely causing you to push putts.
How to Check: Get into your posture and look down. In the reflection, you should see a centerline running through your ball and towards the target. The goal is to get your eyes directly over the top of this line, giving you a truer visual of the ball-to-hole relationship. If you see the reflection of your eyes on the near side of the line, you're "inside." If you see them on the far side, you're "outside."
Quick Tip: Before even grabbing your putter, practice getting into your putting posture and just adjusting your head position until your eyes are perfectly situated over the line. Doing this separately helps your body learn the position without overthinking the full stroke.
Check #2: Shoulder Alignment – Your Stroke’s Steering Wheel
Your putting stroke path follows your shoulder line. If your shoulders are aimed left (a very common fault for right-handed golfers), it's nearly impossible to make a pure stroke down the target line without some last-second manipulation. Your body will naturally want to swing the putter along the line your shoulders have set.
How to Check: Look at your shoulders in the reflection. Your mirror will have lines running perpendicular to the target line. Your shoulder line should be perfectly parallel to these - and therefore, parallel to your target line. If the reflection shows your lead shoulder (the left shoulder for a righty) pulled back and more visible, your shoulders are "open" and aimed left. If your trail shoulder is too far forward, they are "closed."
Quick Tip: Make a practice stroke while looking at your shoulders. Do they stay square, or do they rotate open during the backstroke? The mirror gives you this crucial feedback to help you rock your shoulders like a pendulum, rather than rotate them like you're hitting a driver.
Check #3: Putter Face Alignment – Where the Ball is Going
At the end of the day, where the putter face is pointing at impact determines a massive 80-90% of a putt's starting direction. You can have a perfect path, but if the face is just one degree open or closed, you'll miss a 10-foot putt.
How to Check: With your eyes and shoulders set, place your putter face behind the ball. The beauty of the mirror is you don’t need to look up at the target. Trust the lines. Use the reflection and the perpendicular lines on the mirror to see if your putter's leading edge is perfectly square to the long target line. You'll be surprised how often what *feels* square is actually a bit off.
Quick Tip: Take note of your left-hand position (for a righty). A "strong" grip, where you see too many knuckles, tends to close the face. A "weak" grip, with the hand too far underneath, tends to open it. The mirror helps you find a neutral grip that returns the putter face to square.
Putting It All in Motion: Drills to Groove a Pure Stroke
Once your static alignment is solid, you can start building a repeatable motion. These drills transition from setup to stroke, turning your newfound alignment into muscle memory.
Drill #1: The Tee Gate Drill
This is a classic for a reason. It gives you instant feedback on your club face at the moment of truth.
- Setup: After aligning with the mirror, take two tees and place them in the ground about 6-8 inches in front of the mirror, creating a "gate" that is just slightly wider than your putter head.
- Execution: The goal is simple: make your putting stroke and send the putter head cleanly through the tee gate after impact.
- Feedback: If you hit the inside tee, you're pulling the putt and closing the face. If you hit the outside tee, you’re pushing it with an open face. This drill forces you to keep the putter face square through the impact zone.
Drill #2: The Stroke Path Check
Not sure if you're taking the putter wildly inside or "looping" it outside on the way back? This one is for you.
- Setup: Use just the mirror. Many mirrors have printed lines that trace the ideal stroke path (either straight or on a slight arc).
- Execution: With or without a ball, take slow-motion backstrokes. Watch your putter head in the reflection and focus on keeping it perfectly aligned with the tracer lines on the mirror.
- Feedback: You will immediately see if you have a tendency to lift the putter, take it back too far inside, or push it away from you. Practice the takeaway repeatedly until tracing the line becomes second nature.
Drill #3: The ‘Eyes Closed’ Feel Drill
This is the final, and most important, step: transferring what you see to what you feel.
- Setup: Use the mirror to get your eyes, shoulders, and putter face into their perfect positions. Rehearse the stroke a few times, seeing the perfection.
- Execution: Now, close your eyes and stroke the putt. Focus entirely on the *feeling* of rocking your shoulders and sending the putter down the line.
- Feedback: This drill bridges the gap between practice and play. It trains your body to recognize the sensation of a pure, fundamentally sound stroke. When you're on the course, you won't have a mirror, but you will have this ingrained feeling to rely on.
Making it Stick: How to Practice with a Purpose
A putting mirror is not a magic wand, it’s a training tool. Its benefits come from consistent, focused use. Ten minutes of deliberate practice with the mirror is far more valuable than an hour of mindlessly raking and hitting putts.
Here’s a simple routine to start your practice sessions:
- 5-Minute Audit: Start every putting session with the mirror. Re-calibrate your fundamentals - eyes, shoulders, face. Make ten strokes without a ball, just checking your alignment and path.
- 10-Minute Drill Work: Use the mirror and a ball. Work on the Tee Gate drill from 3-5 feet. Sink 10-15 putts in a row using the mirror, grooving that short-range confidence.
- 5-Minute Feel Transfer: Now, remove the mirror. Place a couple of balls down near the same spot. Before an you ever look at the cup just to recreate the exact same *feeling* of alignment and stroke path. Finally hit them to regular putts. Then repeat the entire feeling with a longer putt.
Consistency is your best friend. A quick check-in before every round can keep bad habits from creeping in and ensure the good habits are locked in.
Final Thoughts
A putting mirror strips away the mystery. It simplifies improvement by providing undeniable, visual feedback on your setup and stroke, turning guesswork into a repeatable, confident process. By consistently checking your eye position, shoulder alignment, and putter face, you build a foundation that won’t just work on the practice green - it will hold up when you need it most on the course.
Building sound mechanics with tools like a putting mirror is a big piece of the puzzle. Once you're out on the course, combine that technique with smart decisions. This is where I find a tool like Caddie AI to be such a game-changer. Being able to ask for a smart green read or get a simple tip that’ll help you think clearly over a big putt removes doubt and lets you trust the great stroke you’ve been working on.
