An archival backing board is a piece of acid-free, lignin-free board or card stock used in a bag, sleeve, binder page, or frame to support or &#8220;back&#8221; a photo, document, print, or other flat item. If this board is also buffered, it helps neutralize acids in the environment. This post will discuss the types of backing boards we offer and how to use them. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Backing Boards Available at Archival Methods<\/h2>\n\n\n\n<p>All of the boards listed are acid-free, lignin-free, buffered and pass the PAT.

This protects your document in storage and during handling. It also can provide a space to write important information about the photo or artifact. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.archivalmethods.com\/product\/acid-free-14-pt-card-stock\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" width=\"1000\" height=\"753\" data-src=\"https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/86-0810-clear-bag-card-stock-mounted-photo-archival-methods.jpg\" alt=\"\" class=\"wp-image-24221 lazyload\" data-srcset=\"https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/86-0810-clear-bag-card-stock-mounted-photo-archival-methods.jpg 1000w, https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/86-0810-clear-bag-card-stock-mounted-photo-archival-methods-600x452.jpg 600w, https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/86-0810-clear-bag-card-stock-mounted-photo-archival-methods-768x578.jpg 768w\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1000px; --smush-placeholder-aspect-ratio: 1000\/753;\" \/><\/a><figcaption class=\"wp-element-caption\">Old mounted photo on White Card Stock inside a Crystal Clear Bag.<\/figcaption><\/figure>\n\n\n\n<p>Backing board is also useful for <a href=\"https:\/\/www.archivalmethods.com\/blog\/using-archival-window-mats\/\" target=\"_blank\" rel=\"noreferrer noopener\">matting<\/a> and <a href=\"https:\/\/www.archivalmethods.com\/blog\/custom-framing-options\/\" target=\"_blank\" rel=\"noreferrer noopener\">framing<\/a> prints and photos. Use polypropylene <a href=\"https:\/\/www.archivalmethods.com\/product\/mounting-corners-tape\" target=\"_blank\" rel=\"noreferrer noopener\">Mounting Corners<\/a> to safely attach your piece to the backing board. You want all materials enclosing your collection to be archival quality. The most popular backing boards for matting and framing are 2 ply matboard (conservation or museum board) and acid-free foamboard.<\/p>\n\n\n\n<p>If you are selling matted pieces or showing them in a <a href=\"https:\/\/www.archivalmethods.com\/category\/onyx-portfolio-boxes\" target=\"_blank\" rel=\"noreferrer noopener\">portfolio<\/a>, matboard and foamboard are both excellent choices. <a href=\"https:\/\/www.archivalmethods.com\/product\/acid-free-foamboard\" target=\"_blank\" rel=\"noreferrer noopener\">Foamboard<\/a> is stiffer and thicker but 2 ply <a href=\"https:\/\/www.archivalmethods.com\/category\/board-paper\" target=\"_blank\" rel=\"noreferrer noopener\">matboard<\/a> is less expensive. When it comes to framing, some people opt for both.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"card-stock\">Card Stock<\/h2>\n\n\n\n<p>Card Stock is the thinnest and least expensive option. It is a heavy weight paper or cover paper similar to index cards. When it comes to binder pages, this would be your best choice. These also work well inside sleeves and bags. We have white, gray, and black card stock and they vary in weight. White is the heaviest (14 pt), gray is slightly thinner (12 pt), and black is the thinnest (9 pt). Card Stock is listed in two places on our website. <\/p>\n\n\n\n<p>You will find all the sizes for our <a href=\"https:\/\/www.archivalmethods.com\/product\/print-and-slide-pages\" target=\"_blank\" rel=\"noreferrer noopener\">Binder Print and Slide Pages<\/a> under <a href=\"https:\/\/www.archivalmethods.com\/product\/acid-free-paper-inserts\" target=\"_blank\" rel=\"noreferrer noopener\">Card Stock Inserts<\/a>. Inserts are an optional add-on. If the photo is very old, damaged, or dirty it would be good to use card stock behind it when putting photos back-to-back in your pages. Since our card stock is buffered it has acid-neutralizing properties which can be especially helpful for older photos, papers, and newsprint.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.archivalmethods.com\/product\/print-and-slide-pages\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" width=\"1000\" height=\"753\" data-src=\"https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/3.5in-pocket-page-insert-CDV-archival-methods.jpg\" alt=\"Carte-de-visite of a seated young boy stored in an archival binder page with a card stock insert label\" class=\"wp-image-24234 lazyload\" data-srcset=\"https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/3.5in-pocket-page-insert-CDV-archival-methods.jpg 1000w, https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/3.5in-pocket-page-insert-CDV-archival-methods-600x452.jpg 600w, https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/3.5in-pocket-page-insert-CDV-archival-methods-768x578.jpg 768w\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1000px; --smush-placeholder-aspect-ratio: 1000\/753;\" \/><\/a><figcaption class=\"wp-element-caption\">A vintage carte-de-visite photograph in our 3-1\/2 x 5 Print Page for 3-ring binders. The white card stock insert fills space in pockets when they are larger than your photos and also provides room for a caption.<\/figcaption><\/figure>\n\n\n\n<p>Using card stock inserts in binder pages is helpful when you have images that are smaller than the pocket size. These pages are designed to hold photos back-to-back in a pocket. You don&#8217;t always need to use a card stock insert in your pocket pages. They do add bulk (black adds the least amount of bulk) so that you won&#8217;t fit as many pages in your binder when you use them.<\/p>\n\n\n\n<p>Card stock is also popular as a support inside <a href=\"https:\/\/www.archivalmethods.com\/category\/enclosures\/\" target=\"_blank\" rel=\"noreferrer noopener\">Enclosures<\/a> like bags and sleeves. You will also find <a href=\"https:\/\/www.archivalmethods.com\/product\/acid-free-14-pt-card-stock\" target=\"_blank\" rel=\"noreferrer noopener\">White Card Stock<\/a> and <a href=\"https:\/\/www.archivalmethods.com\/product\/black-gray-card-stock\" target=\"_blank\" rel=\"noreferrer noopener\">Black &amp; Gray Card Stock<\/a> under our <a href=\"https:\/\/www.archivalmethods.com\/category\/board-paper\" target=\"_blank\" rel=\"noreferrer noopener\">Board and Paper<\/a> category. If you don&#8217;t see the size you need order the next size up and request that we trim it to the size you need (we will cut an entire package down to one size, not multiple sizes).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"mat-board\">2 Ply Mat Board<\/h2>\n\n\n\n<p>The most economical backing board for matting is <a href=\"https:\/\/www.archivalmethods.com\/product\/pearl-white-conservation-board-br-2-ply\" target=\"_blank\" rel=\"noreferrer noopener\">2 ply Pearl Conservation Board<\/a>.

Of all the options listed here, the 4 ply mat boards are the most expensive backing option.<\/p>\n\n\n\n<p>If you opt for a 4 ply window with a 4 ply backer you could go up to about a 16 x 20 size before needing to add additional support (like foamboard) in your frame. At which point I would likely opt for either just a foamboard backing or a 2 ply backing with additional foamboard.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"bag-stiffeners\">Archival Bag Stiffeners <\/h2>\n\n\n\n<p>We began offering <a href=\"https:\/\/www.archivalmethods.com\/product\/bag-stiffeners-acid-free\" target=\"_blank\" rel=\"noreferrer noopener\">Archival Bag Stiffeners<\/a> again in 2025. We have these in sizes from 8 x 10 up to 16 x 20 and they are made from the gray and white boxboard that we use to make our <a href=\"https:\/\/www.archivalmethods.com\/category\/metal-edge-boxes\" target=\"_blank\" rel=\"noreferrer noopener\">Metal Edge Boxes<\/a>. They are a bit more expensive than 2 ply mat board but they are heavier and stiffer. Bag Stiffeners are 1\/16&#8243; thick, while 2 ply is 1\/32&#8243; thick. The Bag Stiffeners are the same thickness as 4 ply mat board but less expensive.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"993\" height=\"448\" data-src=\"https:\/\/blog.archivalmethods.com\/wp-content\/uploads\/142-810-bag-stiffeners-print-bag-BLOG.jpg\" alt=\"Vintage sepia photo of a young mens' basketball team taken outside.
