A Rigid Custom Sign That Ships Flat and Weighs Almost Nothing
A styrene sign is the lightweight middle ground between a flimsy paper poster and a heavy metal panel. The .020" white styrene sheet is thin, so it weighs almost nothing and ships flat, but it holds its shape well enough to sit in a frame, tape to a wall, or slot into a sign holder without curling. Whether you need a retail display, a menu board, an event placard, or a short outdoor run, it puts a crisp, full-color message exactly where you want it. Styrene signs start at $29 for a single 11" x 17" panel, rated 4.9 out of 5 across 60 reviews.
These panels punch above their weight. They cost little to print, they are easy to handle and mount, and because the print is waterproof and UV-safe, the ink shrugs off a spill indoors and holds its color through a stretch of daylight.

What is a styrene sign?
A styrene sign is a flat, rigid plastic sign printed on .020" white styrene, a thin polystyrene sheet that stays stiff and lies flat. At 4OVER4.COM styrene signs print full color in 14 sizes, from a default 11" x 17" up to a custom 48" x 96", and the material is waterproof and UV-safe.
Think of it as a business poster that finally holds its own shape. Instead of a paper print that sags and tears, you get a clean white panel that stands in an easel, tapes to a wall, or drops into a sign holder without a fight. You set the size, pick your turnaround, and the price updates live as you go. If you want a corrugated outdoor panel instead, the Standard Coroplast Signs cover that, and styrene sits right beside it as the light, smooth-faced option.
What Is Styrene Printing?
Styrene printing means printing directly onto a thin rigid polystyrene sheet on a flatbed press. Ink is laid on the panel itself rather than on paper that then gets mounted, which gives a smooth semi-rigid sign that ships flat, will not absorb water, and can be cut to any outline you supply.
That puts styrene in two clear bands. Indoors it is the everyday panel for retail displays, menu boards, directional signs and event placards, where it sits in a frame, on an easel or taped to a wall and holds its shape. Outdoors the same waterproof, UV-safe sheet handles short runs, an open house weekend, a sidewalk promotion, a season of window messaging, where the sign is coming down again rather than living on a fence for years.
Is 20 mil Styrene Thick Enough for a Poster?
For most posters, yes. The stock here is .020" white styrene, which is 20 mil, about half a millimetre. That is thick enough to stand on its own in a frame, a sign holder or on an easel at sizes up to roughly 24" x 36", where a paper poster would ripple and curl.
Past that, or anywhere the panel hangs from its top edge instead of being supported, 20 mil starts to bow under its own weight. For those jobs add grommets so the load is carried at the corners, or move to a thicker rigid substrate. Mounting flat against a wall also solves it, because the wall does the supporting rather than the sheet.
What sizes do styrene signs come in?
4OVER4.COM offers styrene signs in 14 sizes. The default is 11" x 17", and the range climbs through sizes like 12" x 18", 16" x 20", and 18" x 24", up to a custom size as large as 48" x 96". You choose the size in the configurator and the price follows it.
The right size depends on how far away your sign gets read. An 11" x 17" panel reads well on a countertop, an easel, or beside a door. Step up to 12" x 18", 16" x 20", or 18" x 24" when you want the message to carry across a room or a booth. And when a standard size does not fit the spot, set a custom size anywhere up to a large 48" x 96" sheet. Every size prints on the same .020" white styrene, so the look stays consistent whether you order the small default or the largest custom cut. The full size list is grouped below exactly the way the live configurator presents it, so you know what you can change before you change it.
Styrene Sign Sizes and What Each One Suits
| Size | Where it works |
|---|---|
| 11" x 17" (default) | Counter sign, table tent backer, menu board panel, a notice at eye level beside a till. |
| 12" x 18" | The classic easel size, and the one that drops into a standard A-frame or sidewalk sign insert. |
| 16" x 20" | Wall-mounted display, framed promotional panel, a directional sign read from across a room. |
| 18" x 24" | Open house and event signage, the largest size that still stands comfortably on an easel. |
| Custom cut, up to 48" x 96" | Full-height wall panels, fence and hoarding runs, and any outline that is not a rectangle. |
Fourteen set sizes sit in the configurator between the 11" x 17" default and the 48" x 96" custom ceiling, so pick the one that matches the frame, holder or easel the sign is going into and let the mount decide the size rather than the artwork.
Design it without a designer
You do not need a design background to make a styrene sign look sharp. Start from a professionally built layout in our design templates, then change the colors, copy, and logo in the online editor in minutes. Bold headlines and high-contrast colors read best on a sign, so one strong idea is usually all a panel needs.
Already have your artwork? Skip the editor and download a press-ready blank instead. Each blank template is built at the real trim size with the bleed and safe margin already drawn in, so your design never crowds the cut. Grab the size that matches your order below, drop your art in, and upload.
Wally makes a rigid sign that ships flat
Why a $29 styrene panel is the light, easy way to a custom sign.
A styrene sign starts at $29 and prints on waterproof, UV-safe .020 inch white styrene, so it ships flat, weighs almost nothing, and mounts in seconds. Pick from 14 sizes up to 48 by 96 inch, choose a turnaround as fast as same-day, and Wally gets your sign printed and out the door.

How much do styrene signs cost?
Styrene signs start at $29 for one 11" x 17" sign at 4OVER4.COM. You can order from a single sign up to 100, and the size and turnaround you pick drive the total. The live configurator shows the exact price before you check out.
The entry price of $29 makes a single custom sign genuinely affordable. From there the total moves with two things: the size you choose and how fast you need it. A larger cut uses more material, and a rush speed adds to the base, while the standard 4 business day turnaround keeps the price lowest. You can order anywhere from a single sign up to 100 in one run, and the configurator prices every combination live, so there are no surprises at checkout. Before you print, you can add a free online proof to check your layout and colors, or send your file straight to production when you know it is ready.
What material are styrene signs printed on?
Every 4OVER4.COM styrene sign prints on one material: .020" white styrene, a thin, lightweight rigid polystyrene sheet. It is waterproof and UV-safe, so the ink resists moisture and fading, and the white base makes full-color printing look clean and bright.
Styrene is a rigid plastic sheet, and the .020" gauge here is thin and light, closer to a stiff card than a heavy board. That is the point: it ships flat, weighs almost nothing, and still stands up in a frame or a sign holder. The white base gives your colors a clean surface to sit on, and the waterproof, UV-safe print means the panel suits indoor displays and short outdoor runs. For a permanent, all-weather outdoor install you would reach for a heavier substrate, such as the Reflective PVC Board, but for light, affordable signage that goes up fast, styrene is hard to beat.
Styrene Sign Specifications
| Spec | What you get |
|---|---|
| Stock | .020" White Styrene, the exact name it carries in the configurator. |
| Thickness | 20 mil, roughly half a millimetre, rigid enough to stand in a frame and thin enough to ship flat. |
| Sizes | 14 set sizes from 11" x 17" up to a custom cut as large as 48" x 96". |
| Printing | Full color, one side or both sides, so a hanging sign can face two directions. |
| Weather | Waterproof and UV-safe. Indoors it holds indefinitely; outdoors it is built for short runs and temporary campaigns rather than permanent installation. |
| Grommets | Three grommet options in the configurator, so the panel can be hung or tied rather than only propped. |
| Turnaround | 4 business days standard, with 3-day, 2-day, Next-Day and Same-Day rush production. |
Mounting Styrene Signs
How you mount a styrene panel matters more than the sign itself, because 20 mil supports its own weight well when the load is spread and badly when it hangs off one point.
- Grommeted corners. The right choice anywhere the sign is tied, hung or wired, and the only way to hang a larger panel without it bowing. Pick the grommet option in the configurator rather than punching holes after delivery, which tears the sheet.
- Standoffs. Wall mounting with a shadow gap behind, for lobby and retail signs that want to look installed rather than taped.
- Easel backs and sign holders. The counter and tabletop answer at the smaller sizes, where the panel just has to stand up and stay flat.
- Adhesive strips. Fastest indoor mount for a flat wall, and removable, so it fits short promotions and event signage.
- Frame channels. Slide the panel into a snap frame or poster holder. Because styrene ships flat and stays flat, it loads cleanly where a rolled paper poster fights you.
Indoors, adhesive, easel and frame mounts are all fine. Outdoors, use grommets and fixings, since tape and adhesive strips give up as soon as the panel gets wet or the temperature swings.
How do styrene signs compare to other rigid signs?
Styrene signs are the light, low-cost pick in the rigid range, but they are not your only move. If you are weighing a corrugated outdoor panel, a reflective board, or a wipe-clean surface, it helps to see the trade-off in plain numbers. The chart below lines styrene up against its closest siblings, the Standard Coroplast Signs, the Reflective PVC Board, and the Dry Erase Coroplast, so you can compare the starting price on each before you choose.
Styrene vs PVC vs Aluminum Signs
| Panel | Rigidity | Outdoor life | Weight | Price |
|---|---|---|---|---|
| Styrene, .020" white | Semi-rigid. Holds its shape in a frame or on an easel, flexes if you pick it up by one corner. | Short outdoor runs. Waterproof and UV-safe, made for a campaign rather than a permanent fixture. | The lightest of the three, and it ships flat. | The lowest, from $29 for a single 11" x 17" panel. |
| PVC signs | Fully rigid. Stands unsupported and takes handling without flexing. | Longer outdoors than styrene, the usual pick when a sign stays up through a season or more. | Heavier than styrene, still easy to hang. | More than styrene for the same size. |
| Aluminum signs | The most rigid. It will not flex, dent easily or sag on a post. | The longest, the choice for permanent outdoor installation. | The heaviest, so mounting hardware has to be planned. | The highest of the three. |
The short version: choose styrene when the sign lives indoors or has an end date, PVC when it stays outside for a while, and aluminum when it is going up for good.
