Green Cards
Putting is pretty simple. Figure out the right spot to aim and you’ll make more putts.
So how do you do that? Glad you asked.
Our Green Cards are like the Ultimate Putting Cheat-Sheet. They’ll tell you exactly where to aim for every putt based on the slope and green speed - built with Tour-Proven Data and meticulously tested for accuracy and reliability by top PGA professionals. They even come with a Stimpmeter.
Since our Green Cards rely on slope percentage for accuracy, you might also want to use them alongside our Slope Plate green-reading training tool. We mention it because using them together has led to even better real world results, not because we’re trying to upsell you. Promise.

As a mid-handicap golfer working to improve my short game, I’ve been searching for a putting aid that would help me strike the ball more cleanly and consistently. The WhyGolf Putting Thing has proven to be a valuable addition to my practice sessions. It’s easy to use, gives immediate feedback, and has helped me feel more confident on the greens. I still have a long way to go, but this tool has definitely helped me take the next step in improving my short game.
I absolutely love the Putting Thing. The adjustability of the putter gate and ball gate are like no other. Unlike other putter gates that require tees, the Putting Thing is awesome for indoor and outdoor use and allows me to putt on the putting green and indoor putting mat to ensure I am starting the ball on-line as well as striking the ball in the center of the putter face. Not only that, but the putter and ball gate are unequivocally precise in width, while other gates that require tees often are inconsistent in gate width due to different tee angles into the ground. WhyGolf really hit a home run with the Putting Thing and it is exciting for me to implement it into my everyday putting practice routine.
Thanks for the thoughtful review, Kyle. Let us know if we can do anything for you in the future. -WhyGolf Team
The putting thing has helped me tremendously. It's intuitive to use and helps me start my ball online and hit the center of the clubface as well. It's incredibly easy to use and I love using it before golf tournaments. It’s a great way to gain confidence and it makes putting easier.
The product arrived on schedule and is of solid construction. If I were to nitpick I would make the gates metal also but the plastic are sturdy and have an audible click to know they are in place. I have practiced with it on four separate hour long sessions and I can see improvement. It takes getting used to but I believe the logic behind it is solid. I don't leave the practice session without making 10 straight from around 10 feet and once you get the area tighten down it is difficult. However, it is doable and I think I suck less..
This device combines the best of putting practice tools. It allows you to work on your swing path, face control, and a consistent set up. I am able to fine tune adjustments and know that they are correct. I especially love the alignment track so that I know you I am perfectly aligned on the target before you start practicing.
I have the habit of pushing short putts to the right, the Putting Thing forces me to have a better club head path through the ball.
The putting thing fits perfectly on my perfect practice putting mat. I’ve ended up using it at home a lot more than I thought it would. I like to switch between it and the devil balls to really torture myself. Would definitely recommend.
Green Cards FAQ's
How do the Green Cards work?
Green Cards are designed to be used on the golf course as you play. In a matter of seconds, you'll know exactly how much your putt will break.
Pair Green Cards with our Slope Plate for an unbeatable combination that trains you to read slopes with your feet accurately.
Why did we create the Green Cards?
We created the Green Cards to provide golfers with a definitive edge in precision putting. Recognizing that most golfers lack the time for extensive green-reading practice, our cards streamline the process, enabling accurate putt alignment based on specific green slopes and speeds.
Is the data on the Cards based on the assumption that putts will travel a specific distance past the hole?
Yes. Each data point assumes that the golfer will hit their putts 18" past the hole.
Are the Green Cards USGA legal?
The Green Cards are permitted under the USGA Rules of Golf.
How will I know what card to use?
Your purchase includes a handy Stimpmeter, allowing you to measure the speed of the greens you play on. Once you know speed of the greens, pick the corresponding Green Card and you're ready to go.
How do I know what % slope my putt is?
Many golfers practice with a level on the putting green to train their feet to consistently detect the break percentage. However, time constraints prevent most from regularly engaging in this practice.
Our Slope Plate makes it easy for you to learn how to feel the break from the comfort of home. In case you are interested, here's a link.
What do the numbers in RED on the Cards mean?
Red numbers indicate that you should aim towards the center of the cup, not away from it. For instance, '1/2 B in' in red means you should aim half a ball's width inside the cup's edge.
How do I use the Stimpmeter?
The included Stimpmeter operates identically to the Putting Thing's, ensuring you can measure the speed of greens with precision and consistency. Click here to watch the Stimpmeter video.
