How to Choose a Ballot Box: Compare Materials, Security & Capacity Tips
Posted by My Charity Boxes Team on 18th Oct 2025
Introduction
Selecting the right ballot box is not just a logistical choice — it’s a decision that directly impacts trust, transparency, and the integrity of your election or voting process. Whether you’re managing a government election, corporate vote, charity raffle, or community feedback program, the quality and design of the box determine how securely and efficiently ballots are handled.
A poorly designed box can lead to ballot stuffing, tampering, or even damage from weather and misuse. Meanwhile, a durable, secure ballot box with the right capacity and lock system ensures smooth operation and public confidence.
In this comprehensive guide, you’ll learn how to choose a ballot box based on its material, security level, capacity, and durability. We’ll also cover placement, accessories, and key considerations to make your selection process easier — all while showing why My Charity Boxes is a trusted supplier of high-quality, professional-grade ballot boxes.

Types of Ballot Boxes
Understanding the types of boxes available is the foundation for a secure and efficient voting process. Each material offers distinct advantages depending on your environment, regulations, and security needs.
Metal Ballot Boxes
A metal ballot box is the gold standard for durability and tamper resistance. Constructed from steel or aluminum, it withstands physical impact and attempts at forced entry. Metal boxes are often used in official elections or corporate voting programs where confidentiality and longevity are critical. They are also fire-resistant and can be fitted with advanced locks or seals for enhanced protection.
Ideal for: government elections, universities, banks, and public institutions.
Plastic Ballot Boxes
A plastic ballot box, typically made from high-density polyethylene (HDPE) or polypropylene, offers a balance of security and convenience. It’s lighter than metal, resistant to corrosion, and perfect for both indoor and outdoor use. Some models come with reinforced hinges and weather-sealed lids, making them ideal for portable election setups.
Ideal for: schools, local organisations, and temporary outdoor elections.
Transparent Acrylic Ballot Boxes
Transparency builds public confidence. A transparent ballot box allows observers to verify that the box is empty before use and remains sealed afterward. This design supports accountability and trust, particularly in community or NGO elections. According to aceproject.org, transparency helps demonstrate the integrity of ballot collection and reduces suspicion of manipulation.
Ideal for: community events, charity raffles, and monitored voting stations.
Cardboard Ballot Boxes
A cardboard ballot box is the most economical and lightweight option. It’s easy to assemble, store, and dispose of after use. While less durable, cardboard is an excellent choice for low-risk, short-term events.
Ideal for: school elections, fundraisers, and small local polls.

Capacity Considerations
Choosing the right capacity ensures your box can handle your event’s scale without frequent emptying or risk of overflow.
| Size | Typical Capacity | Best For | Example Use |
|---|---|---|---|
| Small | 100–300 ballots | Small offices, schools | Student councils, internal polls |
| Medium | 500–1,000 ballots | Mid-sized organisations | Local elections, nonprofit votes |
| Large | 2,000+ ballots | City-wide or multi-day voting | Municipal elections, major surveys |
When determining capacity:
-
Estimate participation: Factor in expected turnout plus a 20% buffer.
-
Plan collection frequency: Fewer emptying cycles reduce handling risks.
-
Assess space: Ensure the box fits comfortably in its location.
In official contexts, it’s better to have several medium boxes than one oversized unit, as multiple collection points increase convenience and security oversight.
Slot Design & Anti-Stuffing Measures
The slot is where usability meets security. Poorly designed slots can allow tampering or privacy breaches.
Effective ballot box slot design includes:
-
Narrow openings to limit insertion to one envelope or ballot at a time.
-
Angled slots or internal baffles to prevent reaching inside.
-
One-way flaps that close immediately after insertion.
-
Shielded interiors for privacy so no one can see inside.
Anti-stuffing and anti-tamper mechanisms are particularly important in public settings or unattended drop points.

Locking Mechanisms & Security Options
A locking ballot box protects votes from unauthorized access and provides verifiable integrity. Choose a locking style that matches your risk level and oversight structure.
Cam Locks
These are the most common locks, providing simple yet reliable protection for everyday use. Often key-based, they’re perfect for controlled environments like office elections.
Tamper-Evident Seals
These inexpensive seals visibly show if the box has been opened or interfered with. Combined with locks, they form an effective tamper-evident ballot box solution.
Electronic Locks
For high-security or official government use, electronic locks add digital access control. Some models even track openings for audit purposes.
According to The Elections Group and Forbes, best practices for drop box security include using double locks or paired key access and maintaining a documented chain of custody.

Visibility vs. Opacity
Visibility plays a psychological and regulatory role in ballot collection.
-
Transparent designs: Build confidence and allow visual inspection without compromising integrity. Used in transparent voting processes or public accountability settings.
-
Opaque designs: Offer complete privacy, ideal where anonymity is mandated by election law.
Aceproject.org highlights that while visibility boosts transparency, opaque materials are vital for protecting voter confidentiality in official elections. The correct choice depends on your goals: visibility for trust, opacity for privacy.
Outdoor Use & Weather Resistance
If ballots will be collected outside, ensure your box can withstand the elements. A poorly weatherproofed design can destroy ballots and erode voter trust.
Key outdoor features include:
-
Covered slots to prevent rain entry.
-
Water-resistant seals that protect internal contents.
-
UV-resistant materials that prevent warping and discoloration.
-
Bolted mounts or anchor plates to prevent tipping or theft.
Plastic or metal boxes are best suited for outdoor deployment. Some organisations even use double-box setups — an inner box for ballots and an outer shell for protection.
Accessories & Add-Ons
Accessories enhance convenience, security, and presentation:
-
Tamper seals and numbered tags to prove chain of custody.
-
Mounting bases or stands for stability and visibility.
-
Instructional signage that clarifies voting procedures.
-
Branding or logos for professional presentation and recognition.
-
Internal trays or dividers for easier ballot sorting after collection.
These add-ons make your ballot system not just functional but also user-friendly and credible.
