Custom corrugated plastic signs, printed in our own shop — the same 4 mm coroplast our yard signs are made of, cut to any size you want, from 12" up to a full 4 × 8 sheet. Light, weatherproof and easy to handle, it’s the workhorse board for site signs, event signs and anything that needs to go up today without breaking the budget. Design yours above — the price is quoted instantly as you pick your size — and it’s ready for free local pickup in 2–3 working days.
What you get
- 4 mm corrugated plastic panel, cut to your exact size — 12" minimum side, up to 48" × 96" (a full 4 × 8 sheet)
- Full-color print, edge to edge — photos, background colors, as many colors as you like, no extra charge
- Printed one side or both — pick in the designer and the price follows
- Flutes run the short way on cut-down sizes — the direction sign stakes slide into
How long it lasts
Coroplast is the honest short-term board: waterproof, rot-proof and happy outside for a season or two, at a fraction of the cost of a metal panel. For a sign that stays up year after year, step up to our Thin Metal Sign Board or the Thick Metal Sign Board — same designer, same instant pricing, built for years instead of seasons.

Need a stack of yard signs instead?
This listing is for custom sizes, one board at a time. If what you need is the classic 24" × 18" yard sign — especially five or more of them — our yard signs listing has quantity pricing that gets cheaper per sign the more you order, plus H-stakes.
Local pickup
Corrugated plastic boards are free local pickup at our Johnsonville shop — a 4 × 8 sheet doesn’t survive parcel carriers, so we don’t ship them. Checkout offers pickup and we’ll email you the moment your sign is ready, usually 2–3 working days.
Artwork
Use the designer above to lay out your sign — type, shapes, and your own photo or logo. It shows the panel edge and a safe area so nothing important lands too close to the trim. Upload art at roughly 150 DPI at final size for the sharpest result.
