Signs That Beat the Weather, Not the Budget
Staked into a front lawn, zip-tied to a job-site fence, or pointing the way at an event, the corrugated plastic Coroplast sign is the workhorse of outdoor signage. It prints full color on a bright white surface, stands up on its own, and because it is plastic rather than paper or cardboard, it can go out in Monday's rain and still look sharp the next weekend. A single 12" x 18" starts at $25, and the line holds a 4.7 out of 5 rating across 12 reviews.
These signs punch above their price. A 4mm panel is light enough to carry a stack under one arm, rigid enough to hold flat on a fence, and cheap enough to hand out across a whole neighborhood. Want to see how this sign sits next to the rest of the family? Browse the full coroplast signs range, or stay here and build yours from the choices below.
The price starts at $25 for one 12" x 18" sign, and the configurator takes you from a single sign up to a run of 100. A bigger size, two-sided printing, or add-ons like grommets and an H-stake move the number, and every choice updates the total live, so there is no surprise at checkout.
What Is a Plastic Coroplast Sign?
A plastic Coroplast sign is an outdoor sign printed on corrugated plastic, a lightweight fluted panel. At 4OVER4 these print on 4mm white Coroplast in three fixed sizes from 12" x 18" to 18" x 24" plus an Any Size custom option, full color on one side or both, starting at $25 for a single sign.
Coroplast is the same material behind campaign signs, garage sale arrows, and directional signage at events. You upload your artwork, choose the size, set one-sided or two-sided printing, and the sign prints in full color on a bright white face. The panel is rigid enough to stand on its own yet light enough to carry a stack under one arm. If you want the plain version of this same sign, the Standard Coroplast Signs cover it, and this listing sits right beside it in the lineup.
What Is 4mm Coroplast and How Well Does It Hold Up Outside?
4OVER4 prints these signs on 4mm white Coroplast, a corrugated polypropylene panel with hollow flutes running through the core. The plastic is waterproof and does not soak up moisture, so the sign survives rain, sprinklers, and weeks of direct sun without warping the way paper board would.
Look at the edge of a Coroplast sheet and you see the flutes, the little air channels that run the length of the panel like the ribs in cardboard, only in solid plastic. That structure is what makes 4mm Coroplast both light and rigid. It will not sag on a fence, it will not curl when it gets wet, and it wipes clean with a damp cloth. The 4mm gauge is the standard weight for yard and lawn signs, thick enough to take an H-stake through the flutes and thin enough to keep the per-sign cost low. Store it flat when the season ends and the same sign comes back out next year.
What Sizes Do Plastic Coroplast Signs Come In?
4OVER4 plastic Coroplast signs come in three fixed sizes, 12" x 18", 12" x 24", and 18" x 24". If none of those fit, the Any Size option lets you set custom dimensions in the configurator. The default and lowest-priced size is the 12" x 18".
The 12" x 18" is the classic lawn sign, the right size for a name, a phone number, and an arrow a driver can read from the curb. Step up to the 12" x 24" when you want a wider band for a longer message, and reach for the 18" x 24" when the sign needs to carry from across a parking lot or hold a full real estate rider layout. When a job calls for something off the standard grid, the Any Size option opens custom dimensions so the sign matches the frame or stake you already have. Every spec is grouped below exactly the way the live configurator presents it, so you know what you can change before you change it.
Can You Add Grommets or a Stake for Hanging and Mounting?
Yes. 4OVER4 offers grommets in two placements, top corners only or all four corners, plus an optional H-stake. Grommets let you zip-tie or hang the sign on a fence or post, and the H-stake pushes into the flutes so the sign stands on its own in a lawn or median.
How you mount the sign decides which add-ons you want. Grommets are the reinforced metal rings punched through the corners, and they turn a flat panel into something you can lash to a chain-link fence, hang from a banner frame, or bungee to a railing. Choose top corners only for a sign that hangs down, or all four corners when you want it pulled tight and flat against a surface. The H-stake is the wire ground spike shaped like an H that slides straight into the vertical flutes, so a 12" x 18" becomes a freestanding yard sign in seconds with no tools. Order the sign bare if you already have hardware, or add grommets and a stake and it arrives ready to put up.
How Much Do Plastic Coroplast Signs Cost?
Plastic Coroplast signs start at $25 for a single 12" x 18" sign at 4OVER4. You can order any quantity from 1 to 100 in the configurator. A larger size, two-sided printing, or add-ons like grommets and an H-stake adjust the total, and the tool shows the exact price before you check out.
The entry price is $25 for one 12" x 18" sign, and what moves the number from there is what you ask the sign to do: a bigger 18" x 24" panel costs more than the 12" x 18", printing full color on both sides adds to a single-sided job, and grommets or an H-stake add their own line. Every one of those choices updates the price live, so there is no guessing. Not ready to send files straight to press?

How Do These Compare to the Other Coroplast Signs?
Standard printed Coroplast is the value pick, but it is not your only move. If your job needs a wipe-clean surface you can update by hand, the Dry Erase Coroplast takes a marker, and when the sign has to be seen at night, the Reflective Coroplast bounces headlights back. The chart below lines these up side by side so you can compare the starting price on each before you choose.
Wally plants a sign that beats the weather
Why a $25 Coroplast sign outlasts the rain, the sprinklers, and the sun.
A single 12 by 18 inch Coroplast sign costs $25 and prints on 4mm waterproof plastic, so it stays sharp through rain and weeks of sun. Add grommets to hang it on a fence, or an H-stake to plant it in a lawn. Pick a size, choose one side or two, and Wally prints it fast.
How Fast Can You Get Plastic Coroplast Signs?
4OVER4 prints plastic Coroplast signs on a standard 5 business day turnaround, with 3-day and 2-day rush speeds available. The fastest option ships in 2 business days. You choose the speed in the configurator, and faster turnarounds adjust the price.
Standard production keeps the price at its lowest at 5 business days. When the date is tight, the 3-day and 2-day rush speeds move the same job up the queue, with 2 business days the fastest you can go. You set the speed in one dropdown alongside the size and add-ons. Send print-ready art as a PDF, JPG, or PNG, and if you want a second set of eyes on the layout first, the Free Online Proof option puts a digital proof in front of you to approve before anything goes on press.
