Campaign signs still move votes, and 2026 is the year to get them right. With the Texas primary set for March 3, 2026, candidates running in Tomball and the rest of Harris County have a short window to blanket the right yards, medians, and intersections before early voting starts. This guide covers what the research says about sign impact, the Texas rules that govern where a sign can go, and the sizes and materials that survive a Gulf Coast election season. Every recommendation here is built for a real Tomball ballot, from the school board race to the countywide contests.
Tomball is a city of 12,341 people in Harris County and part of the greater Houston metro, according to the 2020 U.S. Census. That size matters for a local campaign. In a race that small, a few hundred yards of well-placed signs can reach a meaningful share of the people who actually turn out.
Key Takeaways
- Lawn signs raise the advertising candidate’s vote share by an average of 1.7 percentage points, per a four-experiment Yale study.
- The 2026 Texas primary is March 3, with a May 26 runoff and the November 3 general election to follow.
- Texas law bars a property owners’ association from banning political signs from 90 days before an election through 10 days after it.
- Signs may be no larger than four feet by six feet, and they belong on private property, never in the public right-of-way.
- Double-sided coroplast on wire H-stakes is the workhorse format for a Texas campaign, starting around $33 per sign.
Do campaign signs actually win votes?
Measured sign effect, the electorate, and the dates that bound a sign programme
Sources: Green et al., Electoral Studies (Yale); 2020 US Census; Texas Election Code.
Yes. Lawn signs raise the advertising candidate’s vote share by an average of 1.7 percentage points, based on four randomized field experiments published in Electoral Studies by a Yale research team (Green et al., 2016). The same study found a spillover effect of about 1.5 percentage points into adjacent precincts that had no signs at all, and it put the probability that signs help the advertising candidate at roughly 98.8 percent.
That margin is small, but local races are won on small margins. A Tomball city council seat or a Tomball ISD board seat can turn on a few hundred votes. A 1.7-point lift is often the difference between a concession speech and a swearing-in. Signs work in two ways at once: they build name recognition for down-ballot candidates most voters have never heard of, and they signal that a campaign is organized and real. For a first-time candidate, that second signal is worth as much as the first.
When can you legally post campaign signs in Tomball?
Start counting back from the election. The 2026 Texas primary is Tuesday, March 3, 2026, with a primary runoff on Tuesday, May 26 and the general election on Tuesday, November 3, per the Texas Secretary of State. Texas Election Code Section 259.002 says a property owners’ association cannot prohibit a homeowner from displaying a political sign on their own property on or after the 90th day before the election, through the 10th day after it (Texas Election Code 259.002).
For the March primary, that protected window opens in early December 2025. That is your practical start date for asking supporters to plant a sign in an HOA neighborhood. Order early. A late order in February leaves you fighting for yard space that opponents claimed in December. If your race is headed for the May runoff or the November general, the same 90-day math applies to each of those dates, and the timeline resets. Many Tomball campaigns print two batches, one for the primary and a fresh, weather-worn-free set for the fall.
Where to place signs around Tomball, and where not to
The single most common way to lose signs is to put them where they are not allowed. Texas Election Code Section 259.002 lets an HOA require signs to be ground-mounted and limit a homeowner to one sign per candidate or measure, so read the neighborhood rules before you hand out stakes. Off private property, the bigger risk is the public right-of-way. Signs are prohibited in medians, esplanades, and the strip of grass between the sidewalk and the street, and on utility poles, traffic signs, and highway fences. Code enforcement in Harris County pulls those signs regularly, and you lose both the sign and the exposure.
The winning placements in Tomball are private front yards, especially on higher-traffic streets, and commercial lots where a business owner supports your race and gives written permission. Cluster your best signs near the polling locations and along the routes voters drive to reach them, while staying off the public property that surrounds the entrance. We break down the legal and illegal zones in detail in our guide to where yard signs can legally go in the Houston area. For the broader strategy across a Texas election year, our 2026 campaign sign playbook walks through timing, quantities, and messaging.
What size and material survive a Texas election season
Coroplast is the standard for good reason, and the law caps how big you can go. Under Texas Election Code Section 259.002, a political sign displayed under those protections may be no larger than four feet by six feet. Most Tomball yard signs come in at 18 by 24 inches or 24 by 18 inches, which reads well from a moving car without crossing any size line. Corrugated plastic, often called coroplast, is lightweight, waterproof, and cheap enough to buy in volume.
Durability is the real test on the Gulf Coast. Between March heat, spring thunderstorms, and relentless UV, a cheap sign fades and warps fast. A quality coroplast sign printed with UV-stable ink holds its color through a full campaign cycle and beyond, which we cover in our breakdown of how long coroplast signs last outdoors in Texas. Pair the sign with a galvanized wire H-stake so it stands up to Tomball wind, and choose double-sided printing so the message reads no matter which way traffic approaches. If you are weighing stake types for busier corners, our comparison of H-stakes versus A-frames helps you match the mount to the spot.
How many signs your Tomball campaign needs, and what they cost
Budget for volume, because coverage is the whole point. Our coroplast campaign signs start at $33.05 for a base configuration and drop in per-unit price as the quantity climbs, so a run of 100 to 250 signs is realistic for a Tomball council, school board, or precinct race. Decide the split up front: single-sided signs cost less and work for supporter yards, while double-sided signs earn their premium at intersections where cars pass from both directions.
A simple way to size the order: count your priority intersections and multiply by two, add one sign for every committed volunteer household, then add a 15 percent buffer for signs that get lost, stolen, or damaged. Wire stakes and grommets are inexpensive add-ons that determine whether a sign survives its first storm, so do not skip them to save a few dollars. When you are ready, you can configure size, quantity, and printing directly on the campaign signs order page, and call 713-662-3123 if you need a custom size or a rush run before a filing deadline.
Design that makes a roadside sign readable at 40 mph
A sign a driver cannot read in two seconds is a wasted sign. Because signs also lift support in neighboring precincts by about 1.5 percentage points (Green et al., 2016), visibility compounds: a clean design does not just persuade the household that hosts it, it reaches the street around it. Put the candidate name first and biggest, in bold, high-contrast type. Keep the total word count under seven. Add the office being sought and, if space allows, the election date.
Contrast is what carries across a yard. Dark text on a light field, or the reverse, beats any busy color scheme. Skip fine detail, gradients, and photos that turn to mud at a distance. Leave generous margins so the design does not crowd the edge of the board. These same rules apply to any temporary outdoor sign, which is why the coroplast yard signs we print for real estate and events use the identical readability formula. Design once, design for the road, and every sign you plant in Tomball pulls its full weight.
Frequently Asked Questions
When should a Tomball candidate order campaign signs for the 2026 primary?
Order by December 2025. The primary is March 3, 2026, and the HOA sign-protection window under Texas Election Code Section 259.002 opens 90 days before the election, in early December. Ordering early lets you claim yard space before opponents do and leaves room for a reprint if a design changes.
Can my HOA in Tomball take down my political sign?
Not during the protected window. From 90 days before an election through 10 days after it, a property owners’ association cannot ban a political sign on your own property. The association can still require the sign to be ground-mounted, limit you to one sign per candidate, and enforce a size cap of four feet by six feet.
Where is it illegal to put campaign signs around Tomball?
Public right-of-way. That means medians, esplanades, the grass between sidewalk and street, utility poles, and traffic signs. Signs belong on private property with the owner’s permission. Our placement-rules guide maps the legal and illegal zones in detail.
What size and material work best for Texas campaign signs?
Double-sided 18 by 24 inch coroplast on a wire H-stake. Corrugated plastic is waterproof, affordable in bulk, and holds up to Gulf Coast heat and storms when printed with UV-stable ink. Double-sided printing reaches traffic from both directions.
How many campaign signs does a local race need?
For a Tomball city, school board, or precinct race, plan on 100 to 250 signs. Count your priority intersections and volunteer households, then add a 15 percent buffer for signs that are lost or damaged during the season.
