Stake a Sign That Shrugs Off the Weather
You have seen it on every real estate lawn and campaign roadside: corrugated plastic built from two thin sheets of polypropylene with a fluted core running between them, so it stays stiff, sheds water, and weighs almost nothing. A coroplast sign starts at $25 for one 11 by 17 inch panel, rated 4.9 out of 5 across 66 reviews. Print it full color, plant it with an optional H-stake or hang it with optional grommets, and you have an outdoor sign that costs little and lasts through the weeks or months it needs to stand. It is the same board behind the whole coroplast signs printing range, and the one most people meet first as a printed yard sign staked on a lawn or a construction site sign wired to a fence.
A coroplast board is cheap to print, light to ship, and tough enough to leave out in the sun and rain for weeks. The other boards in the family are on coroplast signs printing.
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.
The board we print is 4mm white coroplast, the gauge the temporary sign trade runs on, and the full color print keeps the graphics 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, which prices each choice.
How much do coroplast signs cost
One 11 by 17 inch coroplast sign costs $25, and a single order can run from that one sign to 100 of the same design. Size, a printed back, grommets, an H-stake and the speed each add to the total, and you see the full price before checkout.
A lone directional arrow and a hundred campaign panels are both one order here. The price climbs most with size and with a printed back, less with grommets or an H-stake, and a rush speed adds a set amount on top.

What sizes do coroplast signs come in
Most orders start at the 11 by 17 inch default, and the set sizes step up through 12 by 18, 12 by 24, 16 by 20, 18 by 24, 22 by 28 and 24 by 36 inch to a 30 by 40 inch board. A custom size is made to order up to that 30 by 40 inch limit, which makes 9 sizes in all, and the price moves with the size you pick.
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. The configurator prices whichever size you choose.
A custom coroplast sign or a poster-size board has seven settings, each priced as you pick it.
| Setting | Your choices |
|---|---|
| Size | 9 sizes from 11 by 17 inch to 30 by 40 inch, or a custom size up to 30 by 40 inch |
| Board | 4mm white coroplast |
| Ink | Full color front with a blank back, or full color on both sides |
| Grommets | None, the top two corners, or all four corners |
| H-stake | None, or one wire stake to plant the sign in a lawn |
| Quantity | 1 to 100 signs of a design in one order |
| Proof and speed | Straight to production or a free online proof, then 3 business days standard, 2-day, next-day or same-day |
Coroplast Sizes and Flute Thickness
Coroplast is sold by flute thickness, the depth of the fluted channels running between the two outer sheets. We print on 4mm white coroplast, which is the gauge the temporary sign trade runs on. Here is how the three common gauges differ, so you know when 4mm is the right board and when the job wants something a fabricator makes to order.
| Flute thickness | How rigid it is | Wind | Sizes | What it does to the price |
|---|---|---|---|---|
| 4mm, what we print | Stiff enough to stand on an H-stake and hang flat from grommets, light enough to carry a stack of them under one arm | Holds through normal weather when the flutes run vertically and the stake sits in the flutes. Large panels flex in a gale. | Our 9 sizes, from 11 by 17 inch up to a made-to-order 30 by 40 inch | The reason a coroplast sign is the cheapest board you can plant in a lawn |
| 6mm | Noticeably stiffer, less flex across a wide panel | Better behaved on big panels and in exposed, open sites | Specified from a fabricator, usually for larger panels | Costs more per panel than 4mm for the same printed area |
| 10mm | The most rigid of the three, close to a board rather than a sheet | The gauge for long installs on a fence line or a hoarding that stays up for a season or more | Specified from a fabricator | The most expensive of the three, and more board than a temporary sign needs |
Flute direction is the detail that decides whether a sign survives. On a staked sign the flutes must run vertically, top to bottom, so the two legs of the H-stake slide up inside the channels and the sign stands on its own spine. Flutes running the other way leave nothing for the stake to grip and the sign folds over in the first strong wind. On a hanging sign it is the opposite consideration: grommets go in the corners and the flute direction matters less than reinforcing the holes.
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.
There is one board on this product, 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.

Wally makes a sign that laughs at the weather
Why a $25 sheet of corrugated plastic ends up on every lawn.
One 11 by 17 inch coroplast sign costs $25, prints full color, and shrugs off rain and sun. Pick from 9 sizes, add an H-stake to plant it or grommets to hang it, and Wally has it printed as fast as same-day from NYC.
UV and Fade Resistance Outdoors
Coroplast signs are printed with UV cured ink, which means the ink is set hard by ultraviolet light the moment it is laid down instead of being left to dry into the surface. Two things follow from that. The print does not soak in and lift when it rains, and the cured layer holds its color in direct sun far longer than a water based print on the same plastic.
What actually happens outdoors, in order. For the first weeks the sign looks the way it did leaving the plant. Through a full sun season the darkest areas soften first: reds, deep blues and any large solid go slightly chalky before anything else, because saturated ink has the most pigment to lose and dark areas absorb the most heat. Whites and light backgrounds hold longest, which is why a design with dark type on a white field ages better than white type reversed out of a dark field. After that the plastic itself starts to matter more than the ink, since polypropylene left in permanent sun eventually goes brittle at the edges.
Two honest points about siting. A sign facing south, unshaded, in an open lot ages several times faster than the same sign under a tree or on a north facing fence, so two identical signs planted on the same day rarely fade at the same rate. And a coroplast sign is a temporary sign by design: it is priced and built to do a job over weeks or months, come out of the ground and be replaced, not to be the permanent sign on your building. If the message will still be up next year, an aluminum panel is the cheaper decision over its life.
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, so a batch of campaign panels ordered two weeks ahead rides on the standard 3 days at the lowest cost.
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. The gallery below shows coroplast signs printed in-house at different sizes and layouts, so you can judge how large the type needs to be before you build yours.
Real Rigid Signs Our Customers Printed
Where coroplast signs get planted
- Real estate riders and open house signs. The rider strip under the main listing sign, plus the arrow signs that go out on the corners on a Sunday and come in again that evening. Agents buy them in quantity because they get bent, taken and rained on.
- Election and campaign signs. The classic use: hundreds of the same panel, staked on lawns and verges for a few weeks, then pulled. Print both sides so the sign works for traffic in both directions.
- Event wayfinding. Parking this way, registration ahead, entrance around the back. Weddings, fairs, races, church and school events. Big arrows, few words, planted at every point where someone has to make a decision.
- Jobsite and construction boards. Contractor name and license on the fence, safety and access notices, hard hat area warnings. They live outdoors through the build, get replaced when they take damage, and cost little enough that replacing one is not a decision.
- Parking and property notices. Reserved, tenant parking only, no trespassing, private drive. Grommets and zip ties on a fence or a post rather than a stake, and cheap enough to put one at every entrance instead of one at the main gate.
