The piano hinge, also known as a continuous hinge, is a long, narrow hinge that runs the entire length of the two surfaces it joins. It is commonly used on piano lids, hence the name, but its versatility makes it suitable for various other applications, such as cabinet doors, toolboxes, and even small doors in boats and aircraft.

In this comprehensive guide, we will explore the step-by-step process of cutting a piano hinge to the desired length. This skill is invaluable for any DIY enthusiast or professional woodworker, as it allows for customization and precise fitting of the hinge to the specific requirements of a project.

Understanding how to cut a piano hinge effectively requires attention to detail and the use of the right tools and techniques. By following the instructions provided in this guide, you will gain the knowledge and confidence to tackle this task with ease.

Whether you are embarking on a home improvement project or honing your woodworking skills, mastering the art of cutting a piano hinge will undoubtedly prove to be a valuable addition to your repertoire. So, gather your tools and let’s delve into the intricacies of working with this essential hardware component.


Tools and Materials Needed

Tools and Materials Needed

Before embarking on the task of cutting a piano hinge, it is essential to gather the necessary tools and materials. Having the right equipment at your disposal will not only streamline the process but also ensure precision and safety throughout the task. Here’s a comprehensive list of what you will need:


  • Tape measure or ruler
  • Marker or pencil
  • Workbench or sturdy surface for securing the hinge
  • Safety goggles
  • Clamps
  • Hacksaw or angle grinder with a metal-cutting disc
  • File or sandpaper


  • Piano hinge

Ensuring that you have all the necessary tools and materials readily available will set the stage for a seamless and efficient cutting process. Additionally, don’t forget to prioritize safety by wearing protective eyewear when working with tools and handling metal components.


Step 1: Measure and Mark

Step 1: Measure and Mark

Precision is paramount when cutting a piano hinge, and it all begins with accurate measurements. To kick off the process, place the piano hinge on a flat and stable surface, ensuring that it is fully extended. Use a tape measure or ruler to determine the exact length that the hinge needs to be cut to, based on the dimensions of the surface it will be attached to.

Once you have established the precise measurement, use a marker or pencil to mark the cutting points on the hinge. It is advisable to double-check the measurements to avoid any errors that could compromise the fit and functionality of the hinge once it is cut.

When marking the cutting points, make clear and distinct lines to serve as your cutting guide. These marks will guide the cutting tool and help maintain accuracy throughout the cutting process. Taking the time to measure and mark the hinge correctly will significantly contribute to the overall success of this endeavor.


Step 2: Secure the Hinge

Step 2: Secure the Hinge

Before proceeding with the actual cutting of the piano hinge, it is crucial to secure it in place to prevent any unnecessary movement or slippage during the cutting process. An unsecured hinge can lead to jagged or uneven cuts, compromising the functionality and aesthetics of the hinge.

To secure the hinge effectively, consider using clamps to firmly hold it in place on a workbench or any sturdy surface. This will ensure that the hinge remains stable and stationary, allowing you to focus on the cutting task with confidence. Position the hinge so that the marked cutting points are easily accessible and clearly visible, further facilitating a precise and controlled cutting process.

Additionally, don a pair of safety goggles to protect your eyes from any metal shards or debris that may result from the cutting process. Safety should always be a top priority when working with tools and materials, and taking the necessary precautions will contribute to a safe and successful outcome.


Step 3: Cut the Hinge

Step 3: Cut the Hinge

With the hinge securely positioned and the cutting points clearly marked, it is time to proceed with the cutting process. The method of cutting the piano hinge will depend on the tools available and the specific requirements of the project. Two common tools for cutting a piano hinge are a hacksaw and an angle grinder with a metal-cutting disc.

If using a hacksaw, carefully align the blade with the marked cutting points and begin cutting through the hinge using smooth and controlled strokes. Take care to maintain the straightness of the cut, as this will impact the overall appearance and functionality of the hinge once it is installed.

Alternatively, if an angle grinder with a metal-cutting disc is being used, ensure that the disc is suitable for cutting metal and carefully maneuver it along the marked cutting points. Exercise caution and precision to achieve clean and accurate cuts, avoiding any deviation from the intended cutting line.

Throughout the cutting process, it is essential to maintain a steady hand and a controlled cutting motion to achieve the desired results. Take your time and focus on the task at hand, prioritizing accuracy and precision to ensure that the cut hinge aligns seamlessly with the project requirements.


Step 4: Test the Fit

Step 4: Test the Fit

After completing the cutting process, it is crucial to assess the fit of the newly cut piano hinge to ensure that it aligns perfectly with the intended application. Carefully remove the hinge from the secured position and place it on the surface or object to which it will be attached. Take note of how the cut hinge aligns with the attachment points and assess its overall fit and functionality.

When testing the fit, pay close attention to the alignment of the screw holes and the overall positioning of the hinge on the surface. The hinge should lay flat and align seamlessly with the edges of the surfaces it joins, allowing for smooth movement and optimal functionality.

If the cut hinge fits perfectly and aligns as intended, this signifies a successful cutting process. However, if any adjustments are required, such as slight trimming or filing to refine the edges, take the necessary steps to achieve the ideal fit. Utilize a file or sandpaper to smooth any rough edges and ensure that the hinge fits flawlessly, facilitating smooth movement and a professional finish.

Testing the fit of the cut piano hinge is the final step in the cutting process, and it serves as a critical assessment of the precision and accuracy of the cutting work. By meticulously evaluating the fit, any potential issues can be addressed, ultimately leading to a perfectly tailored hinge that meets the specific requirements of the project.




Mastering the art of cutting a piano hinge is a valuable skill that empowers DIY enthusiasts and woodworking professionals alike to customize and tailor hinges to precise specifications. By following the step-by-step process outlined in this guide, individuals can confidently approach the task of cutting a piano hinge with precision and efficiency.

From measuring and marking the hinge to securing it in place and executing the cutting process, each step plays a crucial role in ensuring a successful outcome. Attention to detail, accuracy, and the use of the right tools are fundamental to achieving clean and precise cuts that seamlessly integrate the hinge into the intended application.

Furthermore, testing the fit of the cut hinge provides an opportunity to fine-tune and perfect the alignment, ensuring that it functions flawlessly and enhances the overall aesthetics and functionality of the project. Whether it’s a piano lid, cabinet door, or any other application, a well-cut piano hinge contributes to a professional and polished finish.

As you embark on your woodworking and DIY endeavors, remember that the ability to cut a piano hinge to perfection adds a valuable dimension to your skill set. Embrace the process, prioritize safety, and enjoy the satisfaction of seamlessly fitting custom-cut hinges that elevate your projects to new heights of craftsmanship.
