Grosvenor House Publishing Target Slope Measuring System for Precise Green Reading

Mastering Green Reading with the Target Slope Measuring System

In this book, Nick Riley, PGA Professional, shares a fresh perspective on how slope informs your putting. The Target Slope Measuring System (SMS) offers a practical framework to see and measure the degree of slope on any putt. By connecting slope to your body position and the influence of gravity, the SMS helps translate terrain into a simple sequence you can use on the practice green and during rounds. With steady practice, you may notice a more confident setup and a clearer line to your chosen target.

The approach is designed to be approachable and repeatable, so you can build consistency without overwhelming theory. It focuses on what you can feel and control moment by moment—your stance, balance, and the cues you rely on to guide the putter along the intended path.

What you will learn

• How slope on a green affects your stance and weight distribution
• How to gauge slope quickly and translate it into aim and pace
• A simple SMS practice routine you can repeat on any green
• Strategies to apply SMS across different green speeds and grain directions

A practical routine you can try

Start with a series of putts on a practice green that show a range of slopes. Observe how weight shifts and where your eyes settle. Use the SMS sequence to decide your starting line, how you position your feet, and how you judge pace. Repeat from varying angles to build familiarity with how slope changes feel from different perspectives.

As you practice, you may notice a growing sense of rhythm and balance. The goal is not a guaranteed result but a practical process that helps you choose lines with greater intention and execute with steadier tempo.

Why this matters on the course

On real greens, slope interacts with speed and grain. The SMS provides a concise mental checklist that helps you read terrain more clearly and make deliberate adjustments to alignment and tempo. The result can be added confidence when facing common putt scenarios, especially under time pressure or variable light conditions.

Key benefits you may notice

• Enhanced green reading awareness for a wider range of putts
• More balanced and stable setups on sloped surfaces
• Consistent tempo and pace as slopes change
• A portable, practice-friendly method you can take to the course
