What is a coroplast sign?
A coroplast sign is a print on corrugated plastic, a fluted polypropylene board that is light, rigid, and weatherproof. At 4OVER4 coroplast signs print full color on 4mm white coroplast, on the front only or on both sides, in 9 sizes from 11 by 17 inch up to a custom 30 by 40 inch, with grommets, an H-stake, and turnaround all set in the live configurator.
Coroplast is the corrugated plastic you have seen on every real estate lawn and campaign roadside. It is built from two thin sheets of polypropylene with a fluted core running between them, so it stays stiff, sheds water, and weighs almost nothing. At 4OVER4 the board is 4mm white coroplast, printed full color so the graphics stay bright out in the sun and rain.
Print the front and leave the back blank, or print both sides when the sign faces traffic from two directions. You set the size, the ink coverage, and the finishing in the configurator, and the price updates as you go.
How much do coroplast signs cost?
Coroplast signs start at $25 for one 11 by 17 inch sign at 4OVER4, and you can order anywhere from 1 to 100 signs in a single run. A larger size, printing both sides, grommets, an H-stake, and a faster turnaround adjust the total, and the configurator shows the exact price before you check out.
The entry price is $25 for a single 11 by 17 inch coroplast sign, and you can order from one sign up to 100 in the same run.

What sizes do coroplast signs come in?
4OVER4 coroplast signs come in 9 sizes. The default is 11 by 17 inch, and the set sizes climb through 12 by 18, 12 by 24, and 16 by 20 inch and more, up to a made-to-order custom size as large as 30 by 40 inch. You pick the size in the configurator and the price follows it.
Start with the 11 by 17 inch sign, the handy size for directional and yard use. Step up to 12 by 18 or 12 by 24 inch for real estate and open-house signs, or 16 by 20 inch when you want the message read from the road. There are 9 sizes in all, and when none of them is exactly right you can order a custom size as large as 30 by 40 inch. Bigger board, bigger presence, and the configurator prices whichever size you choose.
What material and finishing can you choose?
4OVER4 coroplast signs print on one material, 4mm white coroplast, a corrugated plastic board. Ink prints full color on the front with a blank back, or full color on both sides. Finishing adds optional grommets in the top corners or all four corners for hanging, and an optional H-stake for planting the sign in the ground. You can send the file straight to production or request a free online proof first.
The board is one material done right: 4mm white coroplast, rigid enough to stand on a stake and light enough to hang from a fence. For ink you choose a full-color front with a blank back, or full color on both sides when the sign faces two directions of traffic.
Then the finishing that makes a sign usable outdoors: grommets, the reinforced holes for zip ties or hooks, in the top two corners or all four corners, and an H-stake, the wire ground spike that turns a flat board into a lawn sign in seconds.

How fast can you get coroplast signs printed?
4OVER4 prints coroplast signs on four turnaround speeds, from same-day out of the New York City facility to a standard 3 business days, with next-day and 2-day in between. Order by the daily cutoff and a same-day job ships that afternoon. You choose the speed in the configurator, and faster options adjust the price.
Event this weekend, or a listing that just went live? Same-day printing covers the tightest deadline: order by the cutoff and your coroplast signs ship the same afternoon from our NYC plant. When the timeline is roomier, next-day and 2-day sit in the middle, and the standard 3 business days keeps the price lowest. Four speeds, one dropdown, and 99.8% of 4OVER4 orders land on time with 82% shipping early, so the date is not a gamble.
What do people use coroplast signs for?
Coroplast signs work as real estate and yard signs, campaign and election signs, open-house and garage-sale signs, event and directional signage, and construction or site notices. The waterproof corrugated plastic and optional H-stake make them the standard choice for short-term outdoor signs planted in a lawn or hung on a fence.
Because coroplast is cheap, light, and weatherproof, it is the default board for signs that live outside for a while. Real estate agents plant them on every listing. Campaigns line them along roads by the hundred. Homeowners stake them for open houses, garage sales, and graduations. Contractors post them on job sites, and event teams use them for parking and directional arrows.
Add an H-stake and the sign goes straight into the lawn; add grommets and it hangs from a fence or railing. One tough board, a long list of outdoor jobs it handles without complaint.
