How to Stretch Canvas

Stretching your own canvas can be a rewarding experience. It allows for greater control over the size, shape, and quality of your support. There are two ways to stretch a canvas:

  • Traditional Method: Involves pulling the canvas directly against the weave, starting from the center of each side and working towards the corners.

  • Bias Method: Involves pulling the canvas diagonally across the frame, which can result in a more even stretch and a smoother surface.

The traditional method can sometimes lead to puckering and uneven tension, while stretching on the bias can help achieve a drum-tight canvas with minimal distortion. In this guide, we’ll walk you through the process of stretching your canvas using the bias method. Please note, however, that the bias stretching method requires using staples.


Step 1: Gather Your Materials

  • Canvas Roll: Choose the appropriate canvas material, weight, and size for your project.

  • Stretcher Bars: Select bars that are the correct size for your canvas.

  • Staple Gun: Use a heavy-duty staple gun with the correct size staples.

  • Staples: Choose staples that are long enough to penetrate the stretcher bars and secure the canvas.

  • Measuring Tape: Use a tape measure to ensure accurate measurements.

  • Charcoal or Pencil: Use a charcoal pencil or a regular pencil to mark the center points.

  • Scissors or Canvas Pliers: Use scissors or canvas pliers to trim excess canvas.

  • Step 2: Prepare the Canvas

    Cut a piece of canvas slightly larger than the stretcher frame, leaving enough excess to wrap around the back.

  • Step 3: Mark the Center

    Use a tape measure to locate the center of one of the shorter bars; mark with charcoal. Then mark the center of the corresponding side of the canvas.

  • Step 4: Position the Stretcher Frame

    Position the stretcher frame lift-side down on the canvas, making sure the frame is aligned with the weave of the canvas.

  • Step 5: Secure the Center

    Staple one side in the center, pulling to the ends for a tight stretch. Make sure to place your staples diagonally, not parallel with the sides.

  • Step 6: Pull Across

    Pull across to the opposite bar, staple the center, and repeat.

  • Step 7: Stretch and Secure the Sides

    Pull toward the corners and tighten the remaining sides, working toward the corners. After 12 staples, your canvas will be taut. Fill in the gaps, fold the corners neatly, and tack the excess fabric to the back.

  • Step 8: Finish the Edges

    Remove staples spanning each joint. Wrap excess fabric around the back of the frame and staple.
