Tempered glass vs acrylic frames: Learn the pros and cons of each for artwork and photography. Discover which is best for clarity, UV protection, and safety with examples from Frame Amo’s D Group (tempered glass) and A Group (acrylic) frames.

When framing your artwork, posters, or photography, one of the key decisions is choosing the right protective cover. Two popular options are tempered glass and acrylic (plexiglass). Each has unique benefits and limitations, and understanding these can help you preserve and display your work effectively.

Benefits and Disadvantages

Tempered Glass

Benefits Disadvantages
Excellent scratch resistance Heavy, especially in larger frames. Luckily, our Signature Glass Frames come pre-installed with professional hanging hardware, tested for weight-bearing capacity, to simplify this process as much as possible. 
Crystal-clear display for professional artwork Can still break under impact. At Frame Amo, we've rigorously tested our packaging materials to ensure safe transit of all our frames containing glass materials. 
Safer than standard glass if broken Typically more expensive
Ideal for small to medium frames that will remain stationary UV Protection can vary by product
Professional-grade clarity (e.g., Frame Amo’s Signature Glass Frames) Not ideal for frequent handling or transport


Acrylic (Plexiglass)

Benefits Disadvantages
Lightweight and easy to hang Can scratch more easily than glass
Virtually unbreakable Attracts dust and static
Excellent UV protection (e.g., Studio Series Frame Packs block 95% UV) Some lower-quality acrylic may yellow over time, though premium options like Frame Amo's plexiglass products resist this
Easier to transport and handle Slightly less crystal-clear than high-quality glass
Safe for homes with children or high-traffic areas Not ideal for ultra-high-end gallery displays


Key Differences Between Tempered Glass And Plexiglass

Tempered glass is heat-treated for added strength and is often used for high-end framing. Acrylic, also called plexiglass, is a lightweight, shatter-resistant alternative. The table below highlights the main differences and how you can choose between them:

Feature Tempered Glass Acrylic (Plexiglass)
Weight Heavier, especially in larger frames Lightweight and easier to handle
Durability Strong, scratch-resistant Shatter-resistant but scratches more easily
Clarity Crystal-clear, minimal distortion Clear, but lower-quality acrylic may yellow over time
Safety Can break more easily Virtually unbreakable, safe around children
UV Protection Many options available; check specifications Many provide high UV protection (e.g., Studio Series Frame Packs block 95% UV)
Handling & Transport Heavier and more fragile Easy to transport, hang, and move
Cost Generally higher Typically more affordable

Choosing Between Tempered Glass and Plexiglass

Your choice depends on the specific needs of your display:

  • Use Tempered Glass When: You want maximum scratch resistance, crystal-clear display, or are framing small to medium-sized professional artwork that won’t be moved often.

  • Use Plexiglass When: You need lightweight, shatter-resistant protection, UV protection for sunlight-exposed artwork, or a frame that’s easy to handle, transport, or hang in high-traffic areas.

Plexiglass frames, such as those found in Frame Amo’s Studio Series Frame Packs, illustrate the advantages of this material: lightweight, shatter-resistant, and UV-protective, making them an excellent choice for many applications without sacrificing display quality.


Final Thoughts

Both tempered glass and plexiglass have important benefits and drawbacks. Understanding the differences ensures your artwork stays protected and displayed beautifully for years to come. Whether you prioritize durability and scratch-resistance or lightweight and shatter-resistance, choosing the right cover is key to a lasting, high-quality frame.
