Pre-cut corrugated plastic blanks are the fastest way to make a yard sign: no sheet to cut down, just print or apply vinyl and stake it. The standard 18"x24" blank is the size used for the vast majority of yard, lawn, political, and real estate signs. Each blank is lightweight 4mm corrugated plastic ★ — waterproof, rigid enough to stand up on a wire H-stake, and ready for screen print, digital print, or cut vinyl. Central Sign Supplies ships blanks same day on most orders ★ from our Omaha warehouse, with local pickup available.
Why Buy Blanks Instead of Sheets?
Blanks save labor. If you're producing yard signs, pre-cut blanks arrive in the finished size — no panel saw, no waste, no squaring up. For shops cutting many sizes or buying in bulk by the square foot, full 4'x8' corrugated sheets are the more economical choice. Most sign shops keep both on hand: blanks for standard yard signs, sheets for everything else. See the full Coroplast & Corrugated Plastic lineup for both.

Corrugated Blanks — Frequently Asked Questions
What size are standard yard sign blanks?
18" × 24" on 4mm corrugated plastic is the standard yard sign blank, which is the size we stock. Other sizes can typically be cut from full sheets — call us for custom cuts.
Are these blanks print-ready?
Yes — corrugated plastic blanks accept screen printing, digital and UV flatbed printing, and adhesive vinyl, with no surface prep required.
Do the blanks fit standard yard sign stakes?
Yes. Standard wire H-stakes insert into the flutes of an 18"x24" blank. We stock the stakes alongside the blanks.
