How Many Yard Signs Do You Need to Win a Local Election? The Real Math
For a city council, school board or county race, plan on 200 to 600 yard signs: enough to cover roughly 3 to 5 percent of the households you expect to vote, concentrated on high traffic corners and supporter lawns. That is not a guess. A set of four randomized field experiments led by Columbia University political scientist Donald Green found that lawn signs raise a candidate’s vote share by about 1.7 percentage points on average, an edge that is small but real, and one of the cheapest per vote tools a local campaign can buy.
Key takeaways
- Research by Donald Green of Columbia and Alexander Coppock of Yale, published in Electoral Studies, measured an average lift of about 1.7 percentage points from lawn signs across four randomized experiments.
- The same research found sign effects spill over into adjacent precincts, so clusters along commuter routes work harder than scattered singles.
- A useful planning ratio for local races is one sign per 15 to 30 expected voters, weighted toward intersections and arterial roads.
- Because signs are cut from 48×96 sheets, ordering in sheet friendly quantities such as 96, 200 or 400 pieces of 18×24 keeps the per sign price down.
- Budget for stakes, replacements and a second wave: campaigns typically lose 10 to 20 percent of signs to weather, mowing and removal over a season.
What does the research actually say about yard signs?
The most cited evidence is the 2016 paper by Green, Coppock and coauthors in Electoral Studies, which planted signs in randomly selected precincts for a congressional candidate, a mayoral candidate, a county commissioner candidate and an independent expenditure campaign. The average effect across all four experiments was about 1.7 percentage points of vote share. In a race decided by a few hundred ballots, that margin is the whole game. The authors also observed effects bleeding into neighboring precincts that received no signs, which is why smart campaigns think in corridors, not dots on a map.
How many signs do you need by race type?
Work from expected turnout, not population. Here is a planning table using the one sign per 15 to 30 expected voters ratio, rounded to sheet friendly order sizes for 18×24 signs, which cut 8 per 48×96 sheet.
| Race | Expected voters | Signs at 1 per 15 to 30 | Suggested order |
|---|---|---|---|
| School board or small town council | 2,000 to 5,000 | 70 to 330 | 200 |
| City council, mid size city | 5,000 to 15,000 | 170 to 1,000 | 400 |
| Mayor or county commission | 15,000 to 50,000 | 500 to 3,300 | 600 to 1,000 |
| State legislative district | 30,000 to 80,000 | 1,000 to 5,300 | 1,000 plus |
These are starting points. A hotly contested primary in a small district can justify the high end, while an incumbent with strong name recognition can hold the low end and spend the savings on mail or doors.
Where should the signs go?
- Supporter lawns first. A sign on private property signals a real endorsement from a neighbor, and it is legally the safest placement.
- High traffic intersections with long red lights, where drivers have time to read a name twice.
- Commuter corridors into and out of town, spaced so the name repeats every quarter mile or so.
- Near early voting sites and polling places, outside any legally mandated buffer zone, in the final two weeks.
Never place signs in public rights of way. Nearly all jurisdictions prohibit it, and road crews will pull them. Our guide to political yard sign rules and timing covers rights of way, HOA limits and removal deadlines in detail.
What should a campaign sign budget look like?
Yard signs are priced per sheet of material, not per sign. A 48×96 sheet of 4mm coroplast printed single sided is 66.00 dollars, stepping down to 49.50 dollars at 10 sheets and 45.00 dollars at 51 sheets. An 18×24 sign cuts 8 per sheet, so a 400 piece run uses 50 sheets and lands in the mid 6 dollar range per sign in material, plus 1.88 dollars per step stake. The full arithmetic is worked through in our 2026 yard sign cost breakdown. Campaigns that want maximum name size per dollar should also read the yard sign size comparison before locking artwork.
Design rules that decide whether signs work
- Name first. The candidate name should be the largest element, readable at driving distance. United States Sign Council research puts best impact legibility at roughly 1 inch of letter height per 10 feet of viewing distance.
- Two colors, high contrast. Dark on light or light on dark beats clever palettes.
- Office sought and a short tagline, nothing else. Websites and QR codes rarely earn their space at 45 miles per hour.
- Print double sided. Traffic flows both ways, and single sided signs waste half their placements.

Frequently asked questions
Do yard signs actually win votes?
Randomized experiments by Green and Coppock published in Electoral Studies measured an average gain of about 1.7 percentage points of vote share, enough to swing close local races.
How many yard signs does a city council campaign need?
A practical range is 200 to 600 signs, based on one sign per 15 to 30 expected voters, concentrated on supporter lawns and high traffic corners.
What size should political yard signs be?
18×24 is the standard. It cuts 8 per 48×96 sheet, fits step stakes and holds a readable name at driving distance.
When should campaign signs go up?
Most campaigns deploy 3 to 6 weeks before election day, with a reserve wave for the final week to replace losses and blanket polling routes.
