Quick Answer
The standard yard sign size in the US is 18" × 24" in 4mm corrugated plastic (PP), mounted on a wire H-stake. The common economy size is 12" × 18", the high-visibility size is 24" × 36", and full sheets come in 4 × 8 ft (48" × 96"). A 4mm 18×24 blank weighs roughly 0.45 lb, and a 40 ft high-cube container holds roughly 55,000–65,000 pre-cut 18×24 blanks. For the November 2026 elections, ocean-freight orders should be placed by mid-September 2026.
Standard Yard Sign Sizes at a Glance
Yard signs in the US market have settled on a handful of standard dimensions. Buying standard sizes keeps your cost per piece low, lets you reuse H-stakes across jobs, and matches the bed sizes of most flatbed printers.
| Size (inches) | Typical use | Standard thickness | Approx. weight / pc (4mm) | Pieces per 4×8 ft sheet |
|---|---|---|---|---|
| 12 × 18 | Economy political signs, directional/parking signs | 4mm | ≈ 0.23 lb (105 g) | up to 21 |
| 18 × 24 | The standard: campaign, real estate, contractor signs | 4mm | ≈ 0.45 lb (205 g) | up to 10 |
| 24 × 24 | Real estate, event signage | 4mm | ≈ 0.60 lb (270 g) | 8 |
| 24 × 36 | High-visibility campaign & roadside signs | 4mm | ≈ 0.90 lb (410 g) | 5 |
| 48 × 96 (4×8 ft) | Full sheets for site signs, fencing, cut-downs | 4mm / 6mm / 10mm | ≈ 4.6 lb (2.1 kg) at 4mm | — |
Weights are typical for standard-density 4mm PP sheet (≈700 g/m²) and vary slightly by grade. Custom sizes and densities are available on factory orders.
Which Thickness Do You Need?
| Thickness | Typical sheet weight | Best for | Notes |
|---|---|---|---|
| 4mm | ≈ 650–750 g/m² | Yard signs, campaign signs, short-term outdoor | Industry standard; fits standard H-stakes |
| 6mm | ≈ 1,000–1,200 g/m² | Larger site signs, A-frames, repeated-use signage | Stiffer panel, less flex on 24×36 and up |
| 10mm | ≈ 1,600–2,000 g/m² | Long-term outdoor boards, construction site panels | Also used for reusable boxes and totes |
For election-cycle work, 4mm is almost always the right answer: it survives 2–3 months outdoors, takes UV flatbed printing well, and keeps freight cost per sign at a minimum. If a job calls for larger panels or multi-season use, step up to 6mm or 10mm.
Blanks vs. Full Sheets: the Cost Math
Sign shops can buy full 4×8 ft sheets and cut blanks in-house, or buy pre-cut blanks. Pre-cut usually wins once volume passes a few thousand pieces:
- Cut yield. An 18×24 layout on a 48×96 sheet yields up to 10 pieces — but only with an optimized layout; a simple 2×4 grid yields 8 and wastes 25% of the sheet. Factory die-cutting captures the full yield.
- Labor. Cutting, corner-rounding and stacking 10,000 blanks is days of shop labor that adds $0.05–0.15 per piece.
- Options at zero labor cost. Factory blanks can come corona-treated for ink adhesion, corner-rounded, with or without flute holes aligned for H-stakes, in white or colors, packed in printable-ready stacks.
The practical rule: cut your own for odd sizes and rush jobs; order pre-cut blanks by the pallet or container for election season and recurring sizes.
Container Quantities & Landed-Cost Planning
| Load | 40 ft HQ container (approx.) | Good for |
|---|---|---|
| 18 × 24 in, 4mm pre-cut blanks | ≈ 55,000–65,000 pcs | Wholesale distributors, large print shops |
| 24 × 36 in, 4mm pre-cut blanks | ≈ 28,000–33,000 pcs | Campaign suppliers, roadside signage |
| 4 × 8 ft, 4mm full sheets | ≈ 5,500–6,500 sheets | Shops cutting in-house, mixed sign work |
| Mixed sizes + wire H-stakes | Custom loading plan | One-stop election-season stocking |

On origin: our group produces corrugated plastic sheets and blanks in China and the Philippines. The 2026 US anti-dumping and countervailing duty (AD/CVD) orders target corrugated plastic boxes from China and Vietnam — buyers concerned about duty exposure on PP products can ship from our Philippine factory (Davao, 80,000 m²), which is outside the scope of those orders. Standard US import duties still apply to Philippine-origin goods, and we quote landed cost transparently so you can compare origins line by line.
Timeline: Ordering for the November 2026 Midterms
Election demand is a spike, not a curve — and blanks that arrive after mid-October miss it. Working backward from Election Day, November 3, 2026:
| Milestone | Timing | What happens |
|---|---|---|
| Place ocean-freight order | By mid-September 2026 | Specs confirmed, production slot locked |
| Production | 7–14 days | Extrusion, cutting, treating, packing |
| Ocean transit + customs + inland | 25–35 days | Asia → US port → your warehouse |
| Stock in warehouse | Mid-to-late October | Final campaign print runs, GOTV signage |
Later than that, air freight is the only option and typically erases the cost advantage of importing. If you are reading this in September, this week is the time to lock in quantities.
FAQ
What is the standard yard sign size?
18 × 24 inches in 4mm corrugated plastic. It is the default for political campaign signs, real estate signs and contractor signs. 12 × 18 is the economy size; 24 × 36 is the high-visibility size.
What thickness should a yard sign blank be?
4mm is the industry standard — stiff enough to hold shape on an H-stake, light enough to keep freight cheap. Use 6mm or 10mm for bigger panels or long-term outdoor signage.
How many 18×24 blanks come from a 4×8 ft sheet?
Up to 10 with an optimized cut layout; a simple grid cut yields 8. Factory die-cutting captures the full yield with clean edges and no shop labor.
How many blanks fit in a 40 ft container?
Roughly 55,000–65,000 pieces of 18 × 24 in 4mm blanks, or about 5,500–6,500 full 4×8 ft sheets. We provide an exact loading plan with every quote, including mixed sizes and H-stakes in the same container.
When should I order for the November 2026 elections?
Place ocean-freight orders by mid-September 2026 to have stock in your US warehouse by mid-to-late October.
Are the blanks printable?
Yes — corrugated plastic (PP) blanks accept flatbed UV and screen printing directly. Corona-treated sheets are available for stronger ink adhesion, white or colored, single or double-sided.
