When it comes to canvas prints, choosing the perfect image is just the beginning. From sizing and layout to finish and mounting options, every detail plays a role in how your artwork will ultimately look and last. One of the most underestimated decisions you’ll make during the canvas printing process is the frame thickness—also known as canvas depth.

This might seem like a minor technicality, but when it comes to larger canvas wall art, it’s anything but. The choice between a 3/4-inch frame and a 1.5-inch frame can affect everything from the structure and durability to the visual impact of your print.

So which one should you choose? If your canvas is on the larger side—say, anything 16×20 inches or bigger—a 1.5-inch thick frame is the clear winner. Let’s break down why.

What Is Frame Depth, Anyway?

In custom canvas printing, the canvas fabric is stretched and stapled around a wooden frame called a stretcher bar. The depth of this bar—either 3/4″ or 1.5″—determines how far the canvas will stand out from the wall once mounted.

A thinner 3/4-inch frame offers a slimmer, more compact profile. Meanwhile, a 1.5-inch frame is thicker and provides a deeper, more substantial look—also referred to as a gallery wrap.

While both options may look similar from the front, the differences become more obvious as the canvas size increases.

Why 3/4-Inch Doesn’t Cut It for Large Prints

For smaller canvases, like an 8×10 or 12×12, a thinner 3/4-inch frame can be perfectly adequate. These prints are lightweight and don’t require as much structural support. But as your canvas gets bigger, the stress on the frame increases dramatically.

Thin frames are more prone to:

• Warping or bowing over time.
• Sagging canvas tension, leading to ripples or distortions.
• Uneven hanging, especially in humid or warm environments.

Larger canvases need more reinforcement to maintain their shape and tautness. That’s where the 1.5-inch thick canvas frame makes all the difference.

A Gallery-Worthy Presentation

Have you ever walked through an art gallery or photography exhibit and admired how the canvases seemed to float elegantly off the wall? That’s the power of a gallery wrap—made possible with thicker 1.5-inch frames.

This deeper frame creates a bold, three-dimensional presence that enhances your image without needing a traditional external frame. It instantly makes your piece feel more premium, intentional, and finished.

In contrast, thinner frames tend to get lost on the wall. Especially with large artwork, the 3/4-inch depth can feel underwhelming or even flimsy by comparison.

Seamless Image Wrapping

One of the main benefits of canvas printing is the ability to wrap the image around the edges of the frame. This “wraparound” effect gives the print a continuous, polished look from every viewing angle—perfect for modern and frameless displays.

But when using a 3/4-inch frame, the edge is so narrow that:

• Key image details might get cropped or wrapped awkwardly.
• The sides may need to be printed in a solid color or mirrored design, which can look unnatural.
• The overall finish may not feel as clean or substantial.

On a 1.5-inch frame, however, you have ample space for a natural wrap, allowing your image to flow smoothly across the sides without compromising the main subject.

Hanging Made Easy

Another practical advantage of thicker canvas frames? Easier, safer wall mounting.

A 1.5-inch frame provides more surface area to attach hanging hardware securely—whether it’s a wire, D-rings, or even cleats. It also sits more evenly against the wall, reducing the chance of tilting or uneven positioning.

With a 3/4-inch frame, large canvases may hang awkwardly or shift over time. The lack of depth can also make them more susceptible to damage if bumped or moved frequently.

If your canvas will be hung in a living room, office, or entryway—anywhere it’ll be seen and potentially handled—a thicker frame offers peace of mind.

Durability That Lasts

One of the most important factors in canvas photo printing is how well your piece holds up over time. Especially in large sizes, a canvas should maintain its shape, tension, and quality without sagging or warping.

This is where thicker canvas frames really show their value:

• They resist twisting and bowing under tension.
• They protect against moisture-related warping.
• They maintain proper stretch and support, even years later.

If you’re creating a statement piece for your home or a professional print for a client, you want your canvas to look just as good five years from now as it does today. A 1.5-inch frame gives you that assurance.

What About the Price?

It’s true that gallery wrap canvases cost slightly more than thinner ones—but for larger canvas sizes, the upgrade is well worth it. You’re not just paying for depth—you’re investing in:

• A better viewing experience.
• Improved stability and durability.
• A more professional presentation.

Think of it this way: you wouldn’t hang a large photo print on a wobbly wire frame. So why display your most cherished image on an under-supported canvas?

When Is 3/4-Inch Still the Right Choice?

There are times when 3/4-inch canvas frames are a perfectly good option:

• For smaller prints that will be framed externally.
• When you’re working on a budget-conscious project.
• In multi-print gallery walls, where slimness can be an advantage.

But once your canvas size gets bigger than 16×20, it’s time to upgrade.

Final Thoughts

Choosing a 1.5-inch thick canvas frame for larger prints is about more than just looks—it’s about performance, durability, and value. Whether you’re creating a custom photo on canvas, printing your own artwork, or designing décor for your space, opting for the gallery wrap thickness ensures your piece is built to last and made to impress.

At Canvas Prints Ltd, we recommend 1.5-inch frames for all prints 16×20 inches and up. They not only offer a more refined and elegant appearance but also stand the test of time—on any wall, in any room.

Bigger canvas? Go with the thicker frame. Your art deserves it.
