How to Choose the Right Suggestion Box: Compare Sizes, Materials & Security

Introduction

Every workplace, school, or public organisation wants feedback. Yet one question arises again and again: what type of suggestion box is best?

Choosing the right suggestion box is not a small decision. A poorly matched option might discourage participation or even compromise confidentiality. On the other hand, the right design, size, and security features can turn a simple box into a trusted feedback tool that boosts engagement and trust.

In this guide, we’ll break down how to choose a suggestion box that matches your environment. We’ll compare types, materials, and locks, explain visibility options, and show which models perform best in offices, retail stores, hospitals, and beyond. Along the way, we’ll highlight how My Charity Boxes provides durable, high-quality solutions tailored to your needs.

Box Types Compared

Not all suggestion boxes work the same way. The placement and format make a big difference.

Wall-Mount Suggestion Boxes

Wall-mount suggestion boxes are perfect for tight spaces. Installed in hallways, near break rooms, or outside meeting rooms, they encourage employees to drop feedback without interrupting their workflow. Since they stay fixed in one place, they are harder to tamper with or misplace.

Best for: Offices, staff lounges, and corridors where floor space is limited.

Freestanding Suggestion Boxes

Freestanding models stand tall on pedestals or stands. They naturally draw attention in busy public areas. Because of their size, they often hold more entries and can include larger signage for visibility.

Best for: Retail shops, hospital lobbies, universities, or fundraising events.

Countertop Suggestion Boxes

Compact and portable, countertop suggestion boxes sit on desks or reception counters. They are easy to move, making them useful for temporary programs or rotating campaigns.

Best for: Reception areas, retail counters, or classrooms.

For a broader understanding of the role these formats play, you can explore what a suggestion box is and how it works to collect meaningful input.

Materials: Pros & Cons

The material of your box affects not just its look but also its durability and security.

Acrylic Suggestion Boxes

• Pros: Lightweight, affordable, and available in clear, frosted, or coloured styles. Clear designs showcase participation, motivating others to join in.

• Cons: Less durable than heavy-duty metal, so they are better suited for lower-risk environments.

Ideal for: Offices, schools, or temporary campaigns that value visibility.

Metal Suggestion Boxes

• Pros: Strong, secure, and long-lasting. Often come with reinforced locks and tamper-proof features.

• Cons: Heavier and usually more expensive than acrylic or wood.

Ideal for: High-security environments such as hospitals, banks, or employee suggestion programs where confidentiality is critical.

Wooden Suggestion Boxes

• Pros: Professional, classic, and customisable with branding or signage. They blend well into formal spaces like boardrooms or hotel lobbies.

• Cons: Heavier and less suited for outdoor or mobile use.

Ideal for: Offices, government institutions, and formal settings where style and professionalism matter.

Security Features

A suggestion box is only as effective as the trust people place in it. That trust often comes from strong security features.

Slot Designs

Narrow, angled, or curved slots reduce the risk of peeking or pulling out submissions. This simple design element goes a long way in keeping feedback private.

Locking Mechanisms

Look for boxes that come with integrated locks. A suggestion box with lock ensures that once feedback is submitted, it stays secure until an authorised person collects it. For sensitive environments, choose dual-lock or reinforced steel models.

Tamper Resistance

Extra reinforcement at hinges, bottoms, and corners prevents forced entry. A secure suggestion box should always be tamper-resistant if used in public spaces or for critical employee feedback.

Visibility Choices

Transparency vs privacy is another key factor.

• Clear Acrylic Boxes: These encourage contributions by showing that others are participating. They are excellent for fundraising campaigns or contests where visibility inspires action.

• Opaque or Frosted Boxes: These protect confidentiality and build trust, especially in workplaces. Employees are more likely to leave honest feedback when they know others can’t see their submissions.

When you’re planning an employee feedback program, consider how to create a suggestion box that balances openness and privacy.

Accessories to Enhance Use

Even the best box performs better with the right accessories.

• Card Holders: Provide writing slips for structured feedback.

• Pens and Attachments: Ensure people never abandon feedback due to missing materials.

• Signage: A small sign saying “Share your ideas here” can double engagement rates.

When paired with thoughtful placement — such as near entrances or cafeterias — these extras turn a static box into an engaging tool. For placement guidance, you can review the best spots to put your suggestion box.

Choosing the Right Size by Environment

Different settings demand different box capacities.

• Offices: Medium-sized boxes are often sufficient. They fit comfortably in break rooms or conference areas. An office suggestion box should emphasise privacy and ease of use.

• Retail Floors: Larger freestanding models capture customer input and can handle high traffic. They also support eye-level signage to draw attention.

• Hospitals / Public Spaces: Prioritise durability and security. Metal or reinforced acrylic boxes with locks work best in environments with heavy foot traffic.

Size and placement also tie into program design. When launching, consider how capacity aligns with campaign goals. For full implementation strategies, see our guide on launching a suggestion box program.
