Is glass or acrylic better for custom picture frames?
Written by: Daniel Koren, Co-Founder, Frameology
Key takeaways
Acrylic is the smarter choice for most custom picture frames because it is lighter, shatter-resistant, and offers stronger UV protection than glass.
Frame size drives your glazing choice: glass works for small 4×6 to 8×10 tabletop frames, while acrylic becomes the clear winner at 11×14 inches and larger.
Acrylic excels for large or shippable frames thanks to its lower weight, 10–20× greater impact resistance, safer shipping profile, and museum-grade UV blocking up to 99%.
Glass still makes sense for small, stationary tabletop frames where its scratch resistance and easy cleaning offer practical benefits.
Frameology offers Classic and Luxe frames with glazing already matched to each use case, so you can start framing your favorite memories at Frameology.
How frame size guides your glazing decision
Frame size should guide your choice between glass and acrylic. Size affects weight, shipping risk, and how much stress the glazing puts on the frame hardware and your wall. Here is a simple breakdown by size range.
4×6 to 8×10 inches
At this scale, glass and acrylic both work well. The weight difference is tiny, breakage risk is low, and the frame usually stays on a tabletop instead of shipping across the country. Glass’s scratch resistance is a real advantage here, and its traditional feel suits small tabletop pieces. Frameology’s Classic Table, starting at $39, fits this size range nicely, ships fast, and has a removable backing so you can swap photos whenever a new memory deserves the spotlight.
11×14 to 16×20 inches
At this size, acrylic starts to pull ahead. Frame Destination notes that glass weighs considerably more than acrylic, which can stress the frame moulding and hanging hardware as dimensions grow. At 11×14 and larger, that extra weight becomes meaningful, especially for frames that will be shipped. Acrylic’s shatter resistance also matters more as the glazing panel gets bigger. The Classic Wall, starting at $59, handles this size range well for everyday wall display.
20×30 to 30×40 inches
At large sizes, acrylic becomes the clear choice. Art Academi reports that museum glass glazing for a 24×36 frame alone weighs an estimated 9.4 lbs, which puts serious stress on frame corners, hanging hardware, and wall anchors. Woodman Frames recommends UV acrylic for artworks larger than 40 inches because the weight of museum glass overwhelms the frame and mounting system. For statement-sized pieces, Frameology’s Luxe Wall, starting at $79, uses museum-grade acrylic that blocks 99% of UV rays, matching the conservation standard of top museum glass without the weight or fragility.
Why acrylic wins for large or shippable frames
The size-based guidance above hints at acrylic’s advantages, and understanding the reasons helps you feel confident in your choice. Four factors consistently favor acrylic when frames get bigger or need to travel: weight, shatter resistance, shipping safety, and UV protection.
Weight: Acrylic weighs approximately half as much as glass at equivalent thickness, with a density of roughly 1.19 g/cm³ compared to roughly 2.5 g/cm³ for glass. This difference reduces structural load on the frame, makes handling easier, and can lower shipping costs.
Shatter resistance: Tru Vue states that acrylic is 10 to 20 times more impact-resistant than glass. When acrylic breaks, it tends to crack into large blunt pieces instead of sharp shards, which is a meaningful safety advantage in homes with kids, pets, or busy hallways.
Shipping safety: American Frame explains that for large frames, acrylic reduces overall weight while maintaining strength and clarity and minimizes damage risk during shipping. Glass has a much higher chance of breaking in transit and needs heavy protective packaging.
UV protection: Museum-grade acrylic, like the glazing used in Frameology’s Luxe line, delivers the same 99% UV blocking mentioned earlier, so it meets conservation standards without the weight penalty of glass.
When glass still makes sense for your frame
Glass still plays a role in framing, especially for small tabletop pieces. For 4×6 to 8×10 frames that stay put and never ship, glass offers two clear advantages over acrylic.
Scratch resistance: Glass rates about 5.5 on the Mohs hardness scale, while acrylic typically rates 3 to 4. This makes glass more resistant to everyday scratches from keys, rings, or rough cloths. In high-traffic situations with frequent cleaning, glass keeps its clarity longer than uncoated acrylic.
Easy cleaning: Glass handles standard glass cleaners without a problem, while acrylic needs a dedicated acrylic cleaner and a soft microfiber cloth. For a small tabletop frame that gets handled often, glass’s simple cleaning routine is a practical plus.
The bottom line: when your frame is small, stationary, and never ships, glass is a perfectly reasonable choice. For everything else, especially anything 11×14 and larger, acrylic is usually the better call.
Real-world acrylic trade-offs to keep in mind
Acrylic brings big benefits, but it also comes with a few trade-offs. These rarely outweigh the advantages, yet it helps to know them before you order.
Static: Acrylic can build up a static charge that attracts dust. The simple fix is an anti-static spray applied after cleaning, which cuts dust buildup between cleanings. Anti-static spray is a standard recommendation for acrylic glazing care.
Scratching: Acrylic scratches more easily than glass. Never clean it with paper towels, abrasive cleaners, or ammonia-based glass cleaners, since ammonia will craze and cloud acrylic over time. Light surface scratches on acrylic can often be buffed out with a plastic polishing compound, while scratched glass usually needs full replacement.
Weight and flex: Acrylic’s lighter weight helps large frames, but very large acrylic sheets can flex slightly depending on thickness, temperature, and humidity. Frame Destination notes this usually isn’t an issue for smaller pieces, and professional framers use thicker acrylic for oversized panels to keep them flat.
Cleaning technique: Use a soft microfiber cloth and a cleaner made for acrylic or plastics, or mild soap and water. Spray the cleaner onto the cloth, not directly onto the acrylic. Rinse dust off first so particles don’t drag across the surface.
For most homeowners, these trade-offs feel minor compared to the safety, weight, and UV benefits acrylic provides, especially at larger frame sizes.
How Frameology makes glass vs. acrylic simple
Frameology simplifies the glazing decision by matching materials to each framing line. You choose the style and tier, and the right glazing comes built in.
The Classic Wall starting at $59 is Frameology’s value tier, with great quality, fast shipping, museum-grade acrylic glazing, and a removable backing so you can swap photos anytime. Classic frames usually ship the next business day and typically arrive within a week, which makes them a strong choice for everyday wall display in the 4×6 to 16×20 range.
The Luxe Wall, starting at $79, is Frameology’s museum-quality tier. It’s crafted from premium wood and metal moldings, with acid-free mats, museum-grade acrylic that delivers the 99% UV blocking mentioned earlier, and a sealed kraft paper backing that protects your photo for the long term.

Frequently asked questions
Is acrylic the same as plexiglass for picture frames?
Acrylic, plexiglass, and Perspex are all common names for the same material: polymethyl methacrylate (PMMA). In the framing world, “acrylic glazing” and “plexiglass” describe the same type of product. Quality varies by grade, since standard acrylic offers basic clarity and impact resistance, while museum-grade or conservation acrylic adds UV-blocking coatings that protect photos and artwork from fading. Frameology’s Luxe frames use museum-grade acrylic, which blocks up to 99% of UV rays.
Does acrylic provide the same UV protection as museum glass?
Acrylic can match museum glass for UV protection when both are conservation or museum grade. As noted earlier, both materials block up to 99% of UV rays when manufactured to museum standards. Standard picture glass, by contrast, offers little UV protection unless it’s labeled as conservation or museum glass. The key is to look for “museum-grade” or “conservation” in the description, whether you choose glass or acrylic. Frameology’s Luxe frames include museum-grade acrylic as a standard feature.
How do I clean acrylic glazing without scratching it?
Use a soft microfiber cloth and a cleaner made for acrylic or plastics, or mild soap and water. Spray the cleaner onto the cloth instead of directly onto the acrylic surface. Rinse any dust off first so particles don’t scratch the material as you wipe. Never use ammonia-based glass cleaners, paper towels, abrasive cleaners, or scrubbing pads on acrylic, since ammonia will cloud and craze the surface over time. To reduce dust buildup between cleanings, apply an anti-static spray after each cleaning session.
Does acrylic attract more dust than glass?
Acrylic can attract more dust than glass because it builds up a static charge. This is the most common trade-off people notice with acrylic glazing. The solution is simple: after cleaning, apply an anti-static spray to the acrylic surface. This reduces static buildup and keeps dust from settling as quickly between cleanings, and most acrylic frame owners add this quick step to their routine without much effort.
What’s the weight difference between glass and acrylic for large frames?
Acrylic’s weight advantage, roughly half that of glass, becomes very noticeable at larger sizes. For small frames, the difference barely registers. For large frames, such as 20×30 or 30×40 inches, the lighter weight makes hanging safer and easier. As with the 24×36 frame example mentioned earlier, glass can add nearly 10 lbs to a large frame, which puts real stress on frame corners, hanging hardware, and wall anchors. Acrylic at the same size is dramatically lighter, which reduces load on the frame structure and is one reason many galleries and museums prefer it for large-format work.
When is glass preferable to acrylic for picture frames?
Glass works best for small tabletop frames, roughly 4×6 to 8×10 inches, that won’t be shipped and won’t hang in a high-traffic area. At this scale, glass’s scratch resistance and simple cleaning routine are real advantages. Glass rates about 5.5 on the Mohs hardness scale compared to acrylic’s 3 to 4, which makes it more resistant to everyday scratches. For frames that stay in one place, don’t get handled much, and don’t need to survive shipping, glass is a traditional and reasonable choice. For anything larger, or anything that needs to ship safely across the country, acrylic is usually the smarter option.
Do all gallery walls include hanging templates?
Classic and Luxe gallery walls include life-size gallery wall templates that make installation simple and straightforward. Canvas galleries, Metal galleries, and gallery walls created using Frameology’s Gallery Wall Design Service don’t include templates because their construction and customization work differently and often need more tailored installation approaches.
Ready to frame your favorite memories?
For most people, acrylic offers the clearest answer to the glazing question because it’s lighter, safer, and, at museum grade, just as protective as top-tier glass. Whether you’re framing a 4×6 snapshot for a tabletop or a 30×40 statement piece for your living room wall, Frameology’s frames are built around glazing that fits the job.
Classic frames start at $39 and ship fast. Luxe frames start at $79 and deliver museum-quality, USA-crafted framing with museum-grade acrylic, acid-free mats, and all hanging hardware included. Both lines are backed by over 7,500 verified 5-star reviews and a near-perfect 4.98/5 rating from customers across the country.
