Thin Foam Sheets – 11x17x0.5 in.

Thin, light and ready to cut into anything.

At a half inch thick, these tabloid-size sheets slice like butter, making them the go-to for crisp letters, model walls and layered scenery.

• What you get: 11" × 17" × ½" sheets in 6- or 14-packs.
• Made for: Architecture and school models, cut-out letters and signs, layered terrain, photo backdrops, and insect or butterfly pinning boards.
• The material: White 1 lb density EPS (expanded polystyrene). Smooth, lightweight and rigid.
• Shape & finish: Cuts clean with a hot wire cutter. Use water-based paints and glues; oil- and solvent-based products (including most spray paints) melt EPS.

Larger packs are ideal for classrooms, events and big builds.

Quick answers

Are these styrofoam sheets?
They’re what most people mean when they search for styrofoam: white EPS (expanded polystyrene), a lightweight foam made of tiny fused beads. It’s craft foam, not the blue insulation board. For clean cuts without loose beads, use a hot wire cutter.

What size is each piece?
Each one measures 11 x 17 x ½ inches, and it cuts down easily to any smaller size.

Can I cut letters and shapes from it?
Yes. At ½" thick, a hot wire cutter or sharp craft knife gives crisp edges on letters, windows and detailed outlines.
