Custom Museum Picture Mats

Museum Picture Mats Cut to Your Dimensions

Museum picture mats are intended for framing projects where preservation is the first priority. Our museum collection uses Legion Rising 100% cotton mat board, a material selected for original, valuable, rare, historic, and irreplaceable artwork.

Each mat is cut to the dimensions selected during ordering. You control the outside size that fits the frame and the opening that determines how much of the artwork remains visible. The restrained selection of four neutral colors keeps the presentation quiet and places attention on the artwork rather than the mat.

100% Cotton Board

Legion Rising museum mat board is made from cotton rather than wood-pulp-based decorative board. Its solid construction carries the selected color through the board and exposed bevel.

Standard 4-Ply

Standard 4-ply construction is approximately 1/16 inch thick and produces the familiar beveled opening used for fine art, photographs, documents, and works on paper.

Four Neutral Colors

A focused palette of four neutral colors supports preservation framing without drawing attention away from the artwork. Order samples when subtle undertones are important.

Why Choose Museum Mat Board?

A picture mat sits close to the artwork and often overlaps its edges, so its material matters. Museum board is made for the most preservation-sensitive projects and avoids the decorative paper facing and ordinary pulp core associated with lower-grade mat board. Its cotton construction and neutral presentation make it appropriate when protecting the artwork matters more than maximizing color choice.

Museum matting is one part of a complete preservation system. Appropriate mounting, conservation-quality backing, suitable glazing, adequate frame depth, careful handling, and a stable display environment all contribute to the life of the framed piece. Museum board cannot prevent damage caused by excessive light, heat, moisture, humidity, pollutants, or poor mounting.

Best suited for: original artwork, limited editions, valuable photographs, historic documents, rare prints, heirlooms, and other irreplaceable works on paper.

Museum Mat Board Compared with Other Mat Types

The best mat depends on the artwork's value, replaceability, preservation needs, and design requirements. Museum board offers the highest preservation standard in this collection, but its neutral palette is intentionally much smaller than the color range available in standard archival mat board.

Mat type	Best use	Primary advantage	Important consideration
Museum	Rare, original, valuable, historic, or irreplaceable artwork	100% cotton construction and the highest preservation tier in our mat selection	Available in only four neutral colors
Archival	Photographs, prints, documents, and everyday conservation framing	Conservation-quality construction with a much broader color selection	A strong preservation-minded choice, but below museum board in this collection's material hierarchy
Economy	Replaceable posters, crafts, school projects, and temporary displays	Lower cost for decorative or high-volume framing	Not intended for conservation or preservation framing

How to Size a Custom Museum Mat

A correctly sized mat must fit both the artwork and the frame. Treat the outside dimensions and opening dimensions as two separate measurements.

Measure the artwork. Record its exact width and height, and identify any signature, border, deckled edge, text, or image detail that must remain visible.
Choose the opening. The opening is normally slightly smaller than the artwork so the mat overlaps the edges. Base it on the visible image area rather than assuming it should equal the paper size.
Determine the outside size. The mat's outside dimensions should fit the frame opening. Use the stated frame size or measure an existing mat that already fits.
Review the borders. Confirm that the resulting top, side, and bottom borders create the intended visual balance. A slightly wider bottom border can compensate for optical weight when desired.
Confirm frame depth. Make sure the frame can accommodate the museum mat, artwork, glazing, mounting materials, and backing. Double and triple mats require more interior depth than a single mat.

Do not make the mat opening exactly the same size as the artwork unless exposed paper edges are intentional and the artwork will be supported by another method. A normal mat opening needs enough overlap to retain the art safely behind it.

Choosing a Museum Mat Color, Border, and Layers

Start with the Artwork

Begin with the artwork's paper tone, contrast, and overall temperature. A neutral close to the paper can create a quiet transition, while a slightly lighter or darker neutral can provide clearer separation.

Consider the Frame

Compare the museum board, artwork, and molding together. Warm neutrals often relate naturally to wood and gold finishes, while cooler or brighter neutrals can suit silver, black, white, and contemporary frames.

Add Layers Carefully

A double or triple mat can add depth or a narrow accent, but every visible layer should meet the preservation goals of the project. Confirm that the frame has enough interior depth for the complete package.

Neutral colors can be difficult to judge on a screen. Bright white, warm white, cream, and gray undertones become more obvious when placed beside the artwork. Order a physical sample and view it beside the artwork and frame in the room where the piece will hang.

Custom Museum Picture Mat FAQ

What is a museum picture mat?

A museum picture mat is made from museum-grade board selected for the long-term preservation of artwork. Our museum mats use 100% cotton board with a solid color throughout, providing a stable, conservation-focused border and a clean beveled opening.

What is the difference between museum and archival picture mats?

Both are appropriate for preservation-minded framing, but museum mat board represents the highest preservation tier in our custom mat selection. Standard archival board provides a much wider color range, while museum board is made from 100% cotton and is offered in a smaller selection of neutral colors.

When should I choose a museum mat?

Choose museum mat board for original, valuable, rare, historic, or irreplaceable artwork and for projects where the highest available preservation standard is more important than having a broad color selection.

What is museum mat board made from?

Our museum picture mats are cut from 100% cotton museum board. The board is solid and consistent through its surface and core rather than being made with a separate decorative paper facing.

What colors are available in museum mat board?

This museum mat collection is available in four restrained neutral colors. The limited palette is designed to keep attention on the artwork and reflects the preservation-first purpose of museum board.

How do I determine the opening size for my picture mat?

The mat opening is normally made slightly smaller than the artwork so the mat overlaps its edges and keeps it from falling through the opening. Measure the area you want visible and account for signatures, borders, or important details near the edges before ordering.

How do I determine the outside size of the mat?

The outside dimensions of the mat should fit the inside of the picture frame. When replacing an existing mat, measure that mat. For a new framing project, use the frame size rather than the outside dimensions of the frame molding.

Does a museum mat protect artwork by itself?

No. Museum mat board is one part of preservation framing. Appropriate mounting, backing, glazing, frame depth, handling, and protection from excessive light, heat, humidity, and moisture also affect the long-term condition of artwork.

Should I order a museum mat sample before choosing?

A physical sample is recommended when the exact neutral color matters. Screens and room lighting can shift the appearance of whites, creams, grays, and other subtle tones, so compare the sample beside both the artwork and frame.
