Green Cards
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.

This a great training aid. I use it for weekly practice on my putting. I have had it for just over a month and seen a real decline in 3 putts which have been killing my game. I have seen a 1.8 stroke improvement in putting since using the Putting Thing. I would highly recommend getting one and using it with your Putting practice.
If you take the time to do the calculations, which I feel like will speed up with time, the system works. It’s exactly what I was looking for. I used a leveling app on my phone to get the feel for different slopes on the green. Well made cards, they look like they’ll last. I hope the stimp meter lasts as well as it’s fairly crucial. I could see it getting broken if it gets smashed inside a golf bag.
Was excited to try new Why putter trainer.. A 4 hncp older player who putts decnet, but recently stating the ball on the correct line has been a challenge.. This tool is very challenging to set on a correct line, other than 3 ft straight putts..
In addition, tried the Stipmeter, my club's greens roll generally around 11-11.5..
Numerous attempts with the Stip guide gave results all exceeding 13 -14, ridiculous, the TV guys on the weekends seldom face greens over 14!!!!
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 find my putting thing a great addition to my putting. It has helped me keep my arms tight and straight. Have actually improved my putting in a very short time. I recommend it very strongly to help improve one’s putting.
I have a half dozen putting aids from sticks to marbles to mirrors. This replaces all of it and has helped me work on tempo as well.
This system gives you everything you need to start making putts and cashing checks. The putting thing has greatly improved my start line and the slope board is so easy my 3 year old can use it (mostly for a car ramp). 5 minutes a day in the morning to help improve green reading while drinking coffee! Why Not?? Great job creating an easy to use tool!
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.
