How To Cut Glass: Tips And Techniques

Cutting glass can be a tricky task, but with the right tools and techniques, it can be done easily and safely. In this article, we’ll discuss how to cut glass properly, step by step. Whether you’re a beginner or an experienced glass cutter, these tips and techniques will help you achieve the perfect cut.

Glass Cutting Tools

Before we dive into the process of cutting glass, let’s talk about the tools you’ll need. The most important tool for cutting glass is a glass cutter. There are two types of glass cutters: handheld and automatic. Handheld glass cutters are the most common and are used for most glass cutting tasks. Automatic glass cutters are used for large-scale glass cutting projects. In addition to a glass cutter, you’ll also need a straight edge, a ruler or measuring tape, and a glass breaker or pliers. These tools will help you measure and score the glass accurately.

Preparing the Glass

Before you start cutting the glass, it’s important to prepare it properly. Clean the glass thoroughly with a glass cleaner and a lint-free cloth. Make sure there are no dirt or dust particles on the glass, as they can interfere with the cutting process.

Measuring and Marking the Glass

Measure the glass carefully, and mark the cutting line with a marker or a piece of tape. Make sure the line is straight and even.

Scoring the Glass

Take your glass cutter and hold it at a 45-degree angle to the glass. Apply firm pressure and make a single, continuous score along the cutting line. Make sure the score is deep enough to break the glass cleanly.

Breaking the Glass

Once you’ve scored the glass, it’s time to break it. Place the scored line over the edge of a table or workbench, with the score facing up. Apply gentle pressure to the glass on either side of the score, and it should snap cleanly along the line.


Q: Can you cut tempered glass?

A: No, tempered glass cannot be cut. It is a safety glass that has been treated with heat and chemicals to make it stronger. If you try to cut tempered glass, it will shatter into small pieces.

Q: Can you cut curved glass?

A: Yes, you can cut curved glass, but it requires special tools and techniques. You’ll need a glass cutter with a curved blade, and you’ll need to score the glass carefully along the curve.

Q: How do you cut thick glass?

A: Cutting thick glass requires a specialized glass cutter with a carbide wheel. You’ll need to score the glass several times to make a deep enough groove to break it cleanly.


Cutting glass can be a challenging task, but with the right tools and techniques, it can be done easily and safely. Remember to prepare the glass properly, measure and mark the cutting line accurately, and score the glass deeply enough to break it cleanly. By following these tips and techniques, you’ll be able to achieve the perfect cut every time.
