Stake Your Message Where Everyone Sees It
Plastic signs for business, also searched as core plastic signs or coroplast signs, print full color on 4mm white coroplast in 12" x 18", 12" x 24" or 18" x 24", or a custom size up to 18" x 24". Order 1 to 100, from $25 for one 12" x 18" sign, and add grommets or an H-stake to mount it.
Coroplast, the corrugated plastic behind almost every yard sign, real estate rider, and open-house placard staked in a lawn, is rigid, light, and built to hold up to rain, sun, and wind. Print a plastic sign full color on 4mm white coroplast and it holds up wherever you put it: marking a driveway, promoting a listing, or pointing people to an entrance. Pricing starts at $25, with a 4.8 out of 5 rating across 15 reviews.
A single 12" x 18" sign starts at $25, you size it up to 18" x 24", print one side or both, and add the exact mounting hardware your spot needs. To compare plastic signs with the rest of the range, browse the full plastic collection, or build yours from the choices below.
What Is a Plastic Sign
A plastic sign is a full color graphic printed on 4mm white coroplast, a lightweight corrugated plastic, in 4 size options from a 12" x 18" default up to a custom Any Size at 18" x 24". You can print the front with a blank back or print both sides, and add optional grommets and an H-stake, all chosen when you order.
It is a corrugated plastic, two smooth faces with fluted ribs running between them, so it stays rigid and light at the same time. Print your message across it in full color and the sign reads clearly from the curb and holds up in a rain shower. You set the size, the ink coverage, and the mounting hardware, and the price updates as you go.
What Size Should a Plastic Sign Be
Plastic signs come in 3 preset sizes, 12" x 18", 12" x 24", and 18" x 24", plus an Any Size custom option up to 18" x 24". The default is a 12" x 18" sign, and the price follows the size you pick.
Match the size to the distance people read it from. A 12" x 18" sign is the classic yard-sign shape, easy to plant along a walkway or driveway for an open house or a lawn service. Step up to 12" x 24" when you need a taller shape for a bigger headline, or 18" x 24" when the sign has to carry from across a parking lot. For something in between, the Any Size option lets you set your own dimensions up to 18" x 24", so the sign fits the frame or window you already have. The specs panel below lists all 4 size options and the mounting choices.
Shapes for Custom Corrugated Signs
Every sign on this page is a rectangle, cut to one of three preset sizes or to your own dimensions, so the choice is the proportion and the direction it faces.
- 12" x 18": the classic yard sign rectangle, for a walkway, a driveway, an open house or a lawn service
- 12" x 24": a taller, narrower panel, for a bigger headline or an arrow that points down a path
- 18" x 24": the largest preset, for a sign read from across a parking lot
- Any Size, up to 18" x 24": your own width and height, for a frame, a window or an A-board you already own
Set the width and height in the Any Size option to run the sign portrait or landscape, and build the artwork at that exact size. Plan the orientation before you add an H-stake, since the stake slides into the flutes on the back and holds the sign upright along them.

What Material Are Plastic Signs Printed On
Every plastic sign prints on 4mm white coroplast, a corrugated plastic built from two smooth outer walls with fluted ribs in between. It is rigid, lightweight, and weather resistant, which is why coroplast is the standard for yard signs, real estate signs, and short-term outdoor displays. For listings, see our corrugated plastic real estate signs, and for a solid plastic panel, our PVC signs.
The 4mm thickness suits outdoor signs. It is stiff enough to stand tall on a stake without flapping, yet light enough to hang from grommets or carry a stack under one arm. The white coroplast face gives your colors a clean, bright base, so a logo or a phone number stays sharp and legible outside. Rain, sun, and wind are what coroplast is made for, which is why it holds up through a full open-house season or an election cycle.
How Long Does a Coroplast Sign Last
A coroplast sign lasts through a full open-house season or an election cycle outdoors, which is the job the 4mm board is made for. Rain runs off the plastic face and the fluted core does not soak it up, so a wet week does not soften or warp the sign the way it would a paper board. Direct sun is the slower factor: the board keeps its shape, and the print on a south-facing sign fades before a shaded one does. Wind is the other test, so plant the sign on an H-stake with the flutes running up and down, or pin it flat with grommets in all 4 corners on a fence.
When the season ends, wipe the face with a damp cloth and store the sign flat. A board kept out of the sun comes back out for the next listing or the next campaign, which is why many buyers print a generic sign with a phone number and reuse it.
How Do You Mount a Plastic Sign
Plastic signs offer optional grommets, either in the top 2 corners or all 4 corners, plus an optional H-stake for planting the sign in the ground. Grommets let you zip-tie or hang the sign on a fence or frame, while the H-stake turns it into a freestanding yard sign.
How you mount the sign decides which hardware to add. For a yard sign, choose the H-stake, a metal wire frame that slides into the flutes on the back and pushes straight into grass or soil, so the sign stands on its own. To hang the sign instead, add grommets: pick the top 2 corners to zip-tie it to a fence, or all 4 corners to lash it flat against a railing or a wall. Leave both off and you get a clean printed panel ready for your own frame or A-board.
Can You Print Both Sides of a Plastic Sign
Plastic signs print in full color. You can print 4 color on the front with a blank back, or 4 color on both sides. Double-sided printing suits signs seen from two directions, like a yard sign on a corner lot or a sign that hangs in a walkway.
Think about how people approach the sign. If it sits against a wall or a window, one full color side does the whole job and keeps the cost down. If traffic passes it from both directions, print both sides so no one sees a blank back. Double-sided is the usual pick for freestanding yard signs on the H-stake, where drivers and walkers come at it from either way. Either option prints in true full color, so photos, logos, and bold type all land crisp.
Printing Technology of Coroplast Signs
Core plastic signs print in 4 color process, the cyan, magenta, yellow and black inks that build full color, straight onto the white face of the 4mm coroplast. The bright white board is the base for every color, so a logo, a photo or a phone number keeps its contrast outdoors without a separate white layer. You choose 4 color on the front with a blank back, or 4 color on both sides for a sign read from two directions.
Send a print-ready PDF, JPG or PNG built at the size you ordered. Keep text and phone numbers away from the edges, and set type large and bold, because people read a yard sign from the curb or from a moving car. A free online proof shows the layout before anything prints, and the job runs on a 5 business day standard turnaround.
How Do Plastic Signs Compare to the Rest of the Plastic Range
Plastic signs are the outdoor, large-format member of the plastic family, and a durable card or a reusable board each start at their own price. The Plastic Business Cards put a weatherproof feel in a wallet size, the Plastic Gift Cards are built for swipe-and-keep durability, and the Dry Erase PVC Board gives you a wipeable rigid panel. The chart below lines them up so you can compare before you choose. For where to put the sign, see our outdoor business sign ideas.

Plastic Signs: Frequently Asked Questions
What is coroplast and why is it used for yard signs?
Coroplast is a corrugated plastic, rigid but light, and it is the stock behind almost every yard sign, real estate rider, and open house placard. These signs print full color on 4mm white coroplast, which holds up outdoors through rain, sun, and wind.
What size options do plastic signs come in?
There are four size options: 12" x 18", 12" x 24", 18" x 24", and a custom Any Size up to 18" x 24". A single 12" x 18" sign starts at $25.
Can I hang a plastic sign instead of staking it?
Yes. Add grommets and you can tie or wire the sign to a fence, a railing, or a post. The H-stake option is there when the sign is going straight into the ground instead.
Is it worth printing both sides?
You can print full color on the front with a blank back, or on both sides of the 4mm white coroplast. Both sides is the choice for a sign on an H-stake at a driveway or a corner, where cars approach from two directions. A sign tied flat to a fence with grommets faces one way, so front only does the job there.
How many signs can I order at once?
Any quantity from 1 to 100 is printed to order in a single run. That covers one sign for a driveway as easily as a set for a listing or an event.
How long does production take?
Standard turnaround is 5 business days, with 3-day and 2-day rush speeds. These signs are rated 4.8 out of 5 across 15 reviews.
