How to Analyze Your Golf Swing

What swing analysis actually means

Analyzing your swing means looking at specific positions on video instead of watching the whole motion and forming an impression. Impressions are what got you here.

The motion takes about 1.2 seconds. Your eye cannot process that in real time, and neither can anyone watching you. Slowed down and stopped at the right frames, the same swing becomes readable.

You are looking for two things: where your body is at a handful of key moments, and how long it takes you to get between them.

Film it so it can be analyzed

A bad camera angle makes analysis worse than useless, because you will draw conclusions from a distorted image.

Two angles matter. Down the line means the camera sits behind you on the target line, filming along the direction of the shot. Face on means the camera sits directly in front of your chest. Down the line shows swing plane, posture and hip movement. Face on shows weight shift, head position and arm structure.

Set the camera at hand height, roughly where your hands sit at address. Higher or lower and the shaft angle in the video is not the shaft angle in reality. Stand back far enough that your whole body and the full arc of the club stay in frame throughout the swing, including the follow-through.

Film at 60 frames per second if your phone allows it. At 30fps the clubhead travels far enough between frames that impact frequently falls in the gap between two of them, and impact is the frame you most want to see.

The four positions worth checking

Do not analyze the whole swing at once. Stop at four frames.

Address. Check your spine angle and how far you are from the ball. Most faults further along the swing are already visible here.

Top of the backswing. Where is the club pointing? Has your lead arm stayed reasonably straight? Has your head moved off the ball?

Impact. The single most useful frame in the swing. Are your hips open to the target? Have you kept the spine angle you started with? Is your weight forward?

Follow-through. A balanced finish is evidence that the sequence before it worked. If you fall backwards here, something earlier in the swing forced it.

Compare the same four frames across several swings. A fault that appears once is noise. A fault that appears in every swing is your swing.

How to measure tempo

Tempo is the ratio between how long your backswing takes and how long your downswing takes. It gets talked about constantly and measured almost never.

Tour players cluster around 3:1. Roughly 0.75 seconds from takeaway to the top, roughly 0.25 seconds from the top to impact. What matters is not hitting 3:1 exactly, it is that the ratio stays the same from swing to swing. A repeatable 2.8:1 beats a ratio that drifts between 2.5 and 3.5 depending on the club and how the round is going.

To measure it, mark three points on your video: the start of the takeaway, the top of the backswing, and impact. The time between the first two divided by the time between the last two is your ratio.

In SwingGrade this is the Swing Tempo tool. You set the three points on the timeline and it calculates the ratio for you.

Measure it across five swings rather than one. Under pressure most amateurs speed up the downswing while the backswing stays the same length, which pulls the ratio down. You will only see that pattern across several swings.

A worked example: checking for early extension

Say you watched a tutorial on early extension and want to know whether you actually do it.

Film down the line. Pause at address and draw a vertical line just behind your hips. Now step through to impact and look at where your hips are relative to that line.

If they have moved forward, toward the ball, you have early extension. Not "it felt like maybe" — you can see it against a fixed reference.

This is what a drawing tool is for. A line on the screen turns a vague suspicion into something you can check again next week and see whether it changed.

Comparing swings is where the learning happens

A single swing on video tells you what your swing looks like. Two swings side by side tell you whether something changed.

Three comparisons are worth making: your swing now against your swing a month ago, to see whether a change held. Your practice swing against your real swing, because the difference between them is usually large and usually revealing. Two attempts at the same technical change, to see which one you can actually repeat.

Save a swing at the start of any technical change you are working on. In three weeks it is the only honest reference you will have, because your memory of what your old swing looked like will have quietly updated itself.

Four mistakes people make analyzing their own swing

Changing more than one thing. If you adjust grip and stance in the same session and the ball flight improves, you have learned nothing about which one did it.

Analyzing one swing. One swing shows you one swing. Patterns need five.

Chasing positions instead of the sequence. Copying a professional's position at the top will not help if the movement that produced it is not yours. Sequence and timing transfer between golfers. Static positions often do not.

Analyzing during the round. Swing analysis is practice work. On the course it produces overthinking, and overthinking produces exactly the tension you were trying to remove.

Frequently asked questions

How often should I analyze my swing?

Once per practice session is enough. Film five swings, check the same four positions in each, pick one thing to work on. Filming every shot creates a library nobody reviews.

Do I need special equipment?

A phone and something to lean it against. A tripod helps because a moving camera makes frame comparison unreliable, but it is not the barrier people assume it is.

Can I analyze my swing without a coach?

For spotting what your body does, yes. Video shows you the movement whether or not anyone is standing next to you. For deciding what to change and in what order, a coach is still faster. Video makes those lessons more productive, because you arrive with footage instead of a description.
