Core Elements of Matboard Passepartout Design

Color Selection

Color plays a pivotal role in setting the tone and mood of a framed piece. The right mat color can enhance the artwork’s hues, create contrast, or blend subtly into the background. Neutral tones such as white, ivory, cream, and black remain popular due to their versatility and timeless elegance. These shades work well with a broad range of art styles—from classic oil paintings to modern photography.

For more expressive or contemporary presentations, bold colors like deep navy, burgundy, forest green, or even vibrant jewel tones can add drama and personality. Some framers use double or triple mats with complementary or contrasting colors to create depth and visual interest. Custom mat boards are available in hundreds of colors, including fade-resistant and conservation-grade options, allowing for limitless creative possibilities while protecting the artwork from UV exposure and environmental damage.

Thickness and Width

The thickness and width of a matboard directly affect the visual weight and presence of the framed artwork. Standard matboards typically range from 1-ply to 8-ply in thickness, with thicker mats adding a sense of depth and luxury. A thicker mat can elevate the artwork, creating a floating effect that enhances dimensionality—especially effective in shadow box framing.

Width, or the visible border around the artwork, influences how the eye perceives the piece. A wide mat (3–4 inches or more) creates a spacious, gallery-like presentation, ideal for large artworks or minimalist settings where breathing room is desired. In contrast, a narrow mat (0.5–1.5 inches) offers a clean, modern look that keeps the focus squarely on the image. The choice should reflect the artwork’s scale, the frame style, and the intended display environment.

Texture and Finish

Matboards come in a wide variety of textures and surface finishes, each contributing uniquely to the overall presentation. Smooth finishes provide a clean, contemporary look and are excellent for photographic prints or detailed illustrations. Textured mats—such as linen, canvas, or suede finishes—add tactile richness and can help diffuse light, reducing glare and enhancing visual depth.

Embossed mats feature raised patterns (like geometric designs, floral motifs, or subtle gradients) that introduce a three-dimensional quality to the frame. Metallic or pearlescent finishes reflect ambient light, adding a touch of glamour and sophistication—perfect for formal displays or decorative pieces. When selecting a finish, consider the lighting conditions of the display area and how the surface interacts with shadows and highlights.

Cut-Out Shapes and Multi-Window Designs

While rectangular and square openings are standard, custom matboards allow for creative cut-out shapes that align with the theme or subject of the artwork. Circles, ovals, arches, or even freeform silhouettes can add a whimsical or artistic flair—ideal for children’s art, portraits, or thematic exhibitions.

Multi-window mats are particularly useful for displaying a series of related images—such as family portraits, a timeline of events, or a collection of small sketches. These designs require precise spacing and alignment, often achieved with digital cutting tools. Thoughtful layout planning ensures visual balance and cohesion, turning the mat itself into a curated part of the storytelling process.

Pro Tips for Professional Matboard Design

Important: Always use a sharp blade and proper backing when cutting matboard to avoid jagged edges or tear-out. Dull blades can crush the board’s core, leading to uneven bevels. For valuable or archival pieces, consult a professional framer to ensure preservation and optimal presentation. The right matboard doesn’t just frame the art—it elevates it.

Proper maintenance and understanding of the specifications of mat boards—also known as framing mats or passepartouts—are essential for preserving both the visual appeal and structural integrity of framed artwork. A well-chosen and carefully maintained mat board not only enhances the presentation of the artwork but also protects it from environmental damage, ensuring longevity and professional quality. This guide covers everything from material specifications to best practices in handling, cutting, cleaning, and moisture control.

Important Note: Always use archival-quality, acid-free mat boards when framing valuable artwork. Acidic materials can cause irreversible yellowing, brittleness, and deterioration of paper-based art over time.

Key Specifications of Mat Boards

• Thickness: Mat boards are available in various thicknesses, typically ranging from 1/16 inch (1.6 mm) for standard mats to 1/8 inch (3.2 mm) for heavier-duty applications. Museum-grade or conservation mats may be as thick as 1/4 inch (6.4 mm), offering enhanced rigidity and depth for high-end presentations.
• Standard Sizes: Common pre-cut sizes include 8x10, 11x14, and 16x20 inches, designed to fit widely used frame dimensions. Custom sizes are readily available to accommodate unique artwork or specialty frames.
• Window Cutout Dimensions: The aperture (cutout) should generally be 1 inch smaller than the frame's inner edge to create a balanced border. For artwork support, the opening should be approximately 1/2 inch larger than the artwork itself, allowing the piece to sit securely behind the mat without being visible at the edges.
• Material Quality: High-quality mats are made from acid-free, lignin-free paperboard to prevent chemical degradation and discoloration. These materials are especially crucial for preserving photographs, watercolors, and other sensitive media.
• Aesthetic Options: Available in a wide range of colors, textures, and finishes—including linen, suede, and metallic—mat boards can be customized to complement the artwork and frame style. Double or triple mats can add visual depth and sophistication to the display.

Essential Cutting Tools and Techniques

Precision cutting is critical to achieving clean beveled edges and professional results. Poorly cut mats can detract from the artwork and compromise the overall presentation.

• Recommended Tools: Use a sharp mat knife, a dedicated rotary mat cutter, or a self-healing cutting mat with a straightedge ruler. Dull blades cause frayed or jagged edges, which are especially noticeable on beveled cuts.
• Cutting Direction: Always make cuts in a single, smooth motion. Repeated sawing motions can damage the surface and create uneven edges.
• Surface Orientation: Cut with the colored or finished side facing up to ensure the cleanest possible bevel and to minimize chipping or tearing on the visible surface.
• Measurement Accuracy: Double- or triple-check all measurements before cutting. Even a small error can result in misalignment or an unbalanced appearance. Use a metal ruler and pencil to mark guidelines clearly.
• Bevel Angle: Most mat cutters are designed to produce a standard 45-degree bevel, which creates a shadow line that enhances depth and draws the viewer’s eye toward the artwork.

Handling and Installation Best Practices

How you handle and install the mat board directly affects the cleanliness and safety of the artwork.

• Clean Handling: Always wear cotton or nitrile gloves when touching the mat board or artwork to prevent fingerprints, oils, and dirt from transferring to the surfaces.
• Artwork Placement: Position the artwork on the back of the mat board so that it aligns perfectly with the window opening. Use acid-free mounting corners or photo corners instead of adhesives to avoid permanent damage.
• Alignment: Ensure the artwork is centered and straight. Use a T-square or measuring tape to verify even borders on all sides.
• Layering Order: Assemble the frame in the correct sequence: glass → mat board → artwork → backing board. This protects the artwork from direct contact with the glass while allowing it to breathe if using conservation framing methods.
• Securing the Frame: Use frame clips or points to hold the backing securely. Avoid over-tightening, which can warp the mat or damage the glass.

Regular Cleaning and Storage

Maintaining the cleanliness and structural integrity of your mat board ensures long-term preservation of the framed piece.

• Dusting: Clean the mat surface regularly with a soft, dry microfiber cloth or a fine-bristle brush to remove dust and debris. Avoid wet cleaning methods.
• No Liquids: Never use water, glass cleaner, or household sprays on the mat board. Moisture can cause warping, staining, or mold growth, especially in non-archival materials.
• Storage Conditions: Store unused mat boards in a cool, dry, and dark environment away from direct sunlight, which can cause fading and yellowing over time.
• Flat Storage: Keep mats flat under light pressure (e.g., under a stack of books) to prevent curling or warping.

Moisture and Environmental Control

Humidity and temperature fluctuations are among the most common causes of mat board and artwork damage.

• Stable Environment: Maintain a consistent room temperature (68–72°F) and relative humidity (40–50%) to prevent swelling, shrinking, or buckling of the mat and artwork.
• Moisture Barriers: For valuable pieces, consider using sealed frames with humidity control packets or UV-protective glazing to create a stable microclimate.
• Mold Prevention: If you notice any signs of condensation, musty odors, or mold spots, remove the artwork immediately and allow it to air dry in a clean, ventilated area. Consult a professional art conservator for restoration advice.
• Avoid Bathrooms/Kitchens: Do not hang framed artwork in high-moisture areas like bathrooms or near kitchen sinks, where steam and humidity levels fluctuate dramatically.

Expert Tip: When framing valuable or irreplaceable artwork, consider using conservation-grade matting and framing techniques. These include hinging with Japanese tissue paper, using UV-filtering acrylic, and sealing the frame back to protect against pollutants and pests.

Additional Recommendations

• Label the back of the frame with the artwork title, date, and mat board specifications for future reference.
• Inspect framed pieces every 6–12 months for signs of damage, especially in changing seasons.
• Replace mats if they show discoloration, warping, or mold—even if the artwork appears unaffected.
• For large or heavy frames, use wall anchors and secure hanging hardware to prevent accidents.
• When in doubt, consult a professional framer or conservator for high-value or historically significant works.

By following these detailed specifications and maintenance practices, you can ensure that your mat board passepartout not only enhances the visual impact of your artwork but also contributes to its long-term preservation. Whether you're a hobbyist, artist, or professional framer, attention to detail in material selection, cutting, and environmental care will result in a display that stands the test of time.

Frequently Asked Questions About Passepartouts and Mat Boards in Framing

A passepartout—often referred to simply as a "mat" in North America—is a crucial component in picture framing that serves both functional and aesthetic purposes. It is a thin, flat board with a cutout window that surrounds the artwork or photograph within a frame.

• Function: The passepartout separates the artwork from the glass to prevent moisture buildup and potential sticking, especially important for delicate prints and photographs.
• Support: It provides structural support to the artwork, helping it lie flat and remain centered within the frame.
• Presentation: It enhances visual appeal by creating a border that draws the viewer’s eye toward the center of the image, adding elegance and professionalism to the display.

Passepartouts are commonly made from paper-based materials and come in a wide range of colors, textures, and thicknesses to complement different styles of art and interior decor.

While the terms "mat" and "passepartout" are often used interchangeably, there are subtle distinctions based on regional usage, context, and professional application:

In essence, all passepartouts are mats, but not all mats meet the standards implied by the term "passepartout" in professional art framing circles.

In photographic framing, a mat (or passepartout) plays a vital role in presentation and preservation. It refers to the border—usually made of paperboard—that surrounds a photograph inside a picture frame.

• Visual Enhancement: Mats create breathing space between the image and the frame, allowing the photo to stand out and appear more prominent.
• Depth and Dimension: When layered (e.g., double or triple mats), they add visual depth, making the framed piece more dynamic and sophisticated.
• Protection: By spacing the glass away from the print surface, mats help prevent condensation, sticking, and abrasion—especially critical for inkjet prints and vintage photographs.
• Design Flexibility: Available in hundreds of colors, textures (linen, suede, metallic), and bevel cuts (white core, black core, matching), mats allow customization to match the mood, subject, or environment of the photo.

For example, a warm cream mat might enhance a vintage portrait, while a bold black mat could intensify a modern architectural photograph.

The thickness of a mat board is typically measured in terms of its caliper (usually ranging from 4-ply to 12-ply, where "ply" refers to layers). However, the visible width of the mat border—the part you see around the artwork—is more commonly discussed in centimeters or inches.

Here are recommended guidelines for mat border width based on artwork size and style:

Note: The physical thickness of a standard mat board is typically around 1.5–2 mm (about 8-ply). Thicker mats (e.g., 10–12 ply) are used for durability or layered designs. Always ensure the frame’s rabbet (inner groove) can accommodate the total stack of mats and glazing.

Mat boards are primarily constructed from paper-based materials, but their composition varies significantly depending on quality and intended use:

• Standard Mat Boards: Made from wood pulp or paper fiber, often containing acidic compounds. These are more affordable but can yellow over time and damage artwork through acid migration—making them unsuitable for valuable or long-term displays.
• Acid-Free Mats: Treated to have a neutral pH (around 7.0) and often buffered with calcium carbonate to resist acidity. Ideal for preserving photos and artwork for decades.
• Museum-Quality Mats: Made from 100% cotton rag or alpha-cellulose fibers, which are naturally lignin- and acid-free. These are the gold standard in conservation framing, offering superior durability and archival stability.
• Core Characteristics: Many mats feature a white or black core beneath a surface layer. When cut, the beveled edge reveals this core, adding a decorative effect (e.g., white core for contrast, black core for drama).

For long-term preservation—especially with original artwork, heirloom photos, or collectibles—always choose acid-free or museum-grade mat boards. Look for certifications like “rag content,” “100% cotton,” or “archival quality” when purchasing.
