The thickness of picture frame plastic varies depending on the size of the frame and the type of plastic used. Acrylic, or plexiglass, is a common material used for picture frames and is usually measured in metric. The standard thickness for acrylic picture framing is 3mm or 0.118 inches, which is equivalent to 1/8 inch in imperial measurements. Some sources recommend using thicker acrylic for larger frames, such as 1/4 inch for frames with a shortest dimension of 60 inches or more. The weight of the acrylic and the structural integrity of the frame should also be considered when determining the thickness of the plastic.
| Characteristics | Values |
|---|---|
| Styrene thickness | 1.2mm |
| Perspex thickness | 0.7mm, 2mm |
| Acrylic thickness | 3mm, 0.118" (1/8"), 1/4", 3/16" |
| Plexiglass sheet thickness | 1/8" |

What You'll Learn
Perspex and acrylic are types of plastic used for picture frames
Acrylic is available in a range of thicknesses, with sheets supplied cut to size and ready for installation. The thickness of the acrylic used for a picture frame depends on the size of the frame. For instance, a rule of thumb suggests that for frames with a shortest dimension of up to 40", 1/8" acrylic should be used; for frames between 40" and 60", 3/16" acrylic is recommended; and for frames 60" or larger, 1/4" acrylic should be used.
Another consideration is the weight of the acrylic, as thicker acrylic will increase the overall weight, which may affect the structural integrity of the frame. Acrylic is half the weight of glass, so 1/4" acrylic will weigh the same as glass, and 3/16" acrylic will be 3/4 the weight of glass.
Perspex is a type of acrylic sheet material that is used for picture frames. It offers durability, strength, and shatter resistance, making it a safe option for homes with children or pets. Perspex also provides crystal-clear clarity, allowing for maximum light transmission and enhancing the vibrancy and richness of photos. It is also incredibly lightweight, making it easy to handle and hang.
When installing Perspex or acrylic into a frame, it is important to ensure that the sheet is securely positioned and does not bow or bend. This can be achieved through various methods, including gluing, screwing, or using clear caulking.

Styrene is a type of plastic used for picture frames
While styrene offers benefits in terms of cost and weight, it may not be the best option for those seeking the highest level of clarity and scratch resistance. Acrylic, for example, provides comparable strength and clarity to glass while being more shatter-resistant and lightweight. However, acrylic is typically the most expensive option.
When choosing a glazing material for picture frames, it is essential to consider factors such as cost, weight, clarity, scratch resistance, and shatter resistance. Glass, for instance, is the traditional choice and offers excellent scratch resistance and a classic look. However, it is heavy and brittle, making it prone to shattering.
The thickness of styrene used for picture frames is typically around 1.2mm, as mentioned earlier. This thickness allows for a balance between providing protection for the framed piece and maintaining the benefits of lightweight construction.
In summary, styrene is a cost-effective and lightweight option for picture frame glazing. While it may not offer the same level of clarity and scratch resistance as glass or acrylic, it is a flexible and shatter-resistant choice that is well-suited for various framing projects, especially those on a budget or requiring larger sizes.

Acrylic thickness is usually measured in metric
When it comes to picture framing, the thickness of acrylic sheets can vary depending on the size of the frame and personal preference. A general rule of thumb is that for frames with a shortest dimension of up to 40 inches, 1/8" acrylic is recommended. For frames between 40 and 60 inches, 3/16" acrylic is suggested, while for frames 60 inches or larger, a thickness of 1/4" is often used.
The thickness of the acrylic can impact the overall weight, which may affect the structural integrity of the frame. Thicker acrylic sheets can add more weight, potentially causing issues with the moulding. Additionally, variations in thickness can lead to visible distortions and inconsistencies, detracting from the aesthetic appeal of the frame.
It is worth noting that the thickness of acrylic sheets can also depend on the brand and manufacturer, and it is always advisable to consult their specific guidelines and recommendations.

Thickness depends on the size of the frame
The thickness of plastic picture frames varies depending on the size of the frame. Generally, the larger the frame, the thicker the plastic needs to be to maintain its structural integrity.
For example, one source recommends that for every 12 inches of frame length, there should be at least 1/16" of clearance and 1/4" of engagement. Another source suggests that for a glazing size of 42 1/2 x 62, a thickness of 0.118" (or 1/8") is suitable. This thickness is also available for 8"x10" frames, indicating that it is suitable for smaller frames as well.
However, some people may prefer thicker plastic for larger frames. One source mentions that for a frame with a shortest dimension of 40"-60", a thickness of 3/16" is recommended, while for dimensions of 60" or more, a thickness of 1/4" is suggested. This is to prevent the plastic from bowing, which can occur with thinner plastics.
On the other hand, thinner plastics may be preferred for smaller frames. One person mentions using a 0.7mm thick offcut of perspex for a 53 x 28 cm frame, which they found to look okay once the picture was on the wall.
It's important to consider the added weight as the thickness of the plastic increases, as this can affect the overall structural integrity of the frame. Additionally, thicker plastics may be more expensive, so it's essential to find a balance between thickness and cost.

Thicker acrylic adds more weight and may affect structural integrity
When it comes to picture framing, acrylic thickness is an important consideration. While thicker acrylic sheets offer increased strength and durability, they also add weight, which can affect the structural integrity of the frame.
The weight of thicker acrylic can be a concern, especially when it comes to the frame's ability to bear loads. As the thickness of acrylic increases, so does its weight, and this added weight can put strain on the frame's structure. This is particularly important to consider when using acrylic for glazing, as the weight of the acrylic sheet needs to be adequately supported by the frame.
For example, consider a frame with a glazing size of 42 1/2" x 62". Using a thicker acrylic sheet, such as 1/4", may provide a sturdier look and better durability. However, the increased weight could cause the frame to bow or sag over time, especially if the frame is not designed to bear that weight.
Additionally, thicker acrylic sheets may require more precise cutting and sizing to ensure stability. Minor variations in thickness consistency can lead to misalignments and structural issues, especially in projects that require exact dimensions, such as display cases.
It is worth noting that thicker acrylic sheets are ideal for applications where impact resistance and load-bearing capacity are crucial. Thicker sheets are less prone to cracking or chipping and can support heavier loads without sagging. However, when it comes to picture framing, the added weight of thicker acrylic may be a more significant consideration to maintain the structural integrity of the frame.
