What are stretcher bars?

Stretcher bars, also called stretcher frame bars, are wooden profiles used to create a stretcher frame. Canvas, cotton, or linen is then stretched over this wooden frame. The quality of these bars largely determines how taut and dimensionally stable your canvas remains.

Professional stretcher bars are designed for artistic applications. They fit together neatly, ensure a right-angled construction, and allow the canvas to be stretched firmly. For larger sizes, you can use cross braces or interlocking braces to further stabilize the frame.

Why choose professional stretcher bars?

A painting doesn't begin with the first brushstroke. The quality of your substrate is at least as important. Professional stretcher bars offer clear advantages over lightweight hobby bars or general hardware store lumber.

They provide a sturdier frame, a more tightly stretched canvas, and better support for heavier painting techniques. Especially when working with multiple layers of paint, texture paste, varnish, or large-format canvas, a stable stretcher frame is essential.

Advantages of good stretcher bars:

• Sturdy base for canvas, cotton, and linen
• Suitable for hobbyists, students, artists, and studios
• Ideal for small and large painting formats
• Can be combined with cross braces for extra stability
• Suitable for making your own stretcher frame or stretching canvas
• Professional appearance for salable paintings and exhibitions

Which stretcher bars do you need?

The right choice largely depends on the size of your canvas and the application of your painting.

For small paintings, four individual stretcher bars are usually sufficient. With these, you can create a simple rectangular or square stretcher frame. If you are working on a medium or larger size, it is advisable to add a cross brace. This prevents the frame from bending inwards and helps keep the canvas better tensioned.

For large canvases or heavy painting techniques, extra reinforcement is recommended. Consider a cross brace construction or multiple cross braces to ensure the stretcher frame maintains its shape.

Guideline per size

Small canvases
For studies, small canvases, and hobby projects, standard stretcher bars are often sufficient.

Medium canvases
In addition to the outer stretcher bars, use at least one cross brace for more stability.

Large canvases
Choose sturdy stretcher frame bars with cross braces or interlocking braces. This helps prevent deformation and sagging.

Professional work or sale
Are you working on a painting for a client, gallery, exhibition, or gift? Then a professional frame is always the best choice.

Stretcher bars, cross braces, and stretcher frames in different ratios

In this collection, you will find various components and sizes to assemble your canvas frame. These include individual professional stretcher bars with wedges, cross braces for extra support, and complete stretcher frames in popular ratios such as square, landscape, and panorama. The collection page features products such as Standard Stretcher Bars, Standard Cross Braces, and stretcher frames in 1:1, 3:4, 2:3, and 1:2 ratios.

This allows you to easily choose the frame that suits your work. A square stretcher frame is ideal for modern compositions, portraits, and abstract art. A 2:3 or 3:4 ratio works well for landscapes, still lifes, and classic painting formats. A 1:2 panoramic format is perfect for wide compositions, skyline paintings, or decorative wall art.

Making your own stretcher frame with stretcher bars

Making your own stretcher frame is easier than many people think. With the right stretcher bars, you can quickly build a sturdy frame on which you can tightly stretch your canvas.

Place the bars at right angles to each other, check that the frame is straight, and for larger sizes, add a cross brace. Then, stretch the canvas evenly over the frame and secure it at the back. You can later fine-tune the tension with wedges, ensuring the canvas remains taut.

A self-made stretcher frame gives you maximum freedom. You determine the size, ratio, and quality of your substrate yourself. This makes stretcher bars indispensable for artists who want to build their work professionally.
