Buying Guide

  • Size compatibility: Measure your frames to ensure the backing boards match or can be trimmed to required dimensions, especially for popular sizes like 16×20 and 18×24.
  • Core color and edge finish: White surfaces with brown cores offer classic framing aesthetics and help prevent visible edge impressions on artwork; white cores reduce contrast against light-colored artworks.
  • Thickness and rigidity: A 4-ply thickness (about 1.4 mm) provides sturdy support and reduces bowing, which is important for heavier prints and canvases.
  • Cutting flexibility: Uncut boards let you tailor sizes precisely to fit custom openings, while pre-cut options save time for standard sizes.
  • Color options: Assorted color packs enable creative mats and can highlight certain colors in artwork, but consider whether a uniform white mat better suits your display goals.
  • Acid-free and archival concerns: If longevity is essential, verify acid-free or archival-grade specifications to protect photos and prints from deterioration over time.
  • Packaging and handling: Look for sturdy packaging to minimize warping in transit; a box-packed set helps ensure boards arrive flat and usable.
  • Use cases: Choose boards suited for photos, prints, art pieces, or craft projects, and consider whether you need backers for large-format displays or smaller frames.
  • Budget and quantity: Bulk packs are cost-efficient for frequent framing tasks, studios, or classrooms; smaller sets may be better for occasional hobbyists.

When selecting mat boards, balance size needs, color preferences, and backing strength. For larger formats, prioritize thicker, uncut sheets with white cores to maintain a clean, professional look. For creative projects, assorted color packs can enhance display options without sacrificing protection. A reliable supplier offering multiple sizes in a single brand can also simplify inventory for frequent framing work.
