Business Card Magnet Sizes: Which Size Is Right for Your Australian Business?

Business card magnets come in different sizes, from compact square formats to larger rectangular options. The right size depends on how much information you need to include, how you want customers to use the magnet, and your overall marketing goals.

Choosing the right size is an important part of creating effective Business card magnets. A magnet that is too small may not provide enough space for essential contact details, while an oversized magnet may cost more and take up unnecessary space.

For Australian businesses, the best size depends on how you plan to use your magnets, how much information your design needs, and the type of customers you want to reach.

Whether you’re a tradie, real estate agent, service provider or small business owner, this guide explains the main business card magnet sizes and how to choose the right option for your marketing needs.

The size of your magnet affects more than its appearance. It can influence:

• How much contact information you can include
• How easy your details are to read
• Whether your logo and branding stand out
• Where customers can place the magnet
• Printing and production costs
• How suitable the magnet is for your industry

A well-designed business card magnet should provide enough space for your important information without making the design feel crowded.

The goal isn’t necessarily to choose the largest magnet. The goal is to choose a size that gives your customers the information they need while remaining practical and visually appealing.

Business card magnets are available in different dimensions to suit different businesses and designs.

At FridgeMagnets.com.au, options include compact formats through to larger and custom-shaped magnets.

A 50 × 50 mm magnet is a compact option for businesses that want to keep their design simple.

This size can work well when your main priorities are:

• Business name
• Logo
• Phone number
• Website
• Short service description

It’s particularly suitable when customers already know your business and you simply want to give them a convenient reminder of how to contact you.

Best for:

• Simple business branding
• Short contact details
• Minimalist designs
• Promotional giveaways
• Businesses wanting a compact magnet

If your design contains a lot of information, however, a larger format may be more suitable.

The 50 × 70 mm format gives you additional vertical space while remaining relatively compact.

This can be useful for businesses that want to include a logo, contact details and a short list of services.

The 54 × 90 mm format is particularly useful if you want your magnet to resemble the proportions of a traditional business card.

It provides a familiar horizontal layout for:

• Logo
• Business name
• Name and position
• Phone number
• Email
• Website
• Social media details

This can be a strong choice for professional services and businesses that want their magnet to function as a direct alternative to a conventional paper business card.

If you need more room for your branding and information, a 60 × 120 mm magnet gives you considerably more design space.

This larger format can be useful when you want to include:

• Multiple contact methods
• Several services
• A QR code
• Business hours
• A promotional message
• A larger logo or image

For example, a plumbing business could use the additional space to display its logo, phone number, website, emergency service information and key services.

The important thing is to use the additional space strategically rather than simply adding more text.

Square magnets can give your branding a different visual appearance from traditional rectangular business cards.

They can work particularly well for businesses that want a simple logo-led design.

A square format may suit:

• Cafés
• Retail businesses
• Beauty businesses
• Home services
• Small businesses
• Promotional campaigns

The symmetrical shape can also make a simple logo or graphic stand out.

Larger magnets provide more room for information and visual elements.

They can be useful when the magnet needs to do more than simply provide contact information.

For example, a business might include:

• Logo
• Phone number
• Website
• Services
• QR code
• Opening hours
• Social media information
• Promotional offer

However, more space does not automatically mean a better magnet.

A large magnet with too much information can become difficult to read.

Use additional space to improve hierarchy and readability rather than filling every available area.

If you want your magnet to stand out, a custom shape can be an alternative to standard rectangular or square formats.

This can be particularly relevant for Australian businesses where the shape can reinforce what the company does.

For example:

• A plumbing business could use a plumbing-related shape.
• A real estate business could use a house-shaped design.
• A construction business could use an industry-relevant shape.
• A food business could use a shape associated with its products.

Custom-shaped magnets can turn a simple contact card into a more recognisable promotional item.

Australian tradies often rely on repeat business, referrals and local visibility.

For plumbers, electricians, builders, landscapers, cleaners and other service businesses, the magnet needs to make contacting the business easy.

A practical design could include:

Business name + logo
Main service
Phone number
Website
QR code

For a tradie, choosing a slightly larger magnet can be worthwhile if it allows important information to remain highly readable.

The magnet may be kept on a customer’s fridge for future reference, so contact information should be more prominent than unnecessary marketing copy.

Real estate agents can benefit from magnets because customers may keep useful contact information at home.

A real estate magnet could include:

• Agent name
• Agency logo
• Phone number
• Website
• Property-related branding
• QR code

A medium or larger format can provide enough space for branding without making the design feel crowded.

House-shaped magnets can also be considered where the shape supports the agency’s branding and property-focused positioning.

One of the biggest mistakes businesses make is trying to fit too much information onto a small magnet.

You don’t need to reproduce every detail from your website.

Focus on the information customers are most likely to need.

Prioritise:

1. Business name
2. Logo
3. Phone number
4. Website
5. Main service
6. QR code, where appropriate

You can leave secondary information such as long descriptions or extensive service lists on your website.

The magnet’s job is to make your business easy to remember and easy to contact.

A QR code can be useful when it supports a clear customer action.

For example, it could send customers to:

• Your website
• Booking page
• Quote request form
• Online menu
• Contact page
• Social media profile

However, don’t make the QR code so large that it dominates the entire design.

Make sure there is enough clear space around it and that it remains easy to scan.

A simple way to choose your size is to work backwards from your design.

Choose a smaller magnet if:

• You have minimal information
• Your logo is the main focus
• You want a compact promotional item
• Customers already know your business

Choose a medium magnet if:

• You need contact information and branding
• You want to include a QR code
• You have several services to promote
• You want a traditional business card layout

Choose a larger magnet if:

• You need more information
• You want larger branding
• You need multiple contact details
• The magnet has a promotional or functional purpose

Choose a custom shape if:

• Brand recognition is important
• Your business has a recognisable visual identity
• You want to differentiate your magnet from standard formats
• The shape can reinforce your industry

Before ordering, think about the information you actually need to display.

Start with your essential content and create a hierarchy:

Most important:
Business name, logo and phone number.

Second priority:
Website, service and QR code.

Optional:
Address, opening hours, social media or promotional messaging.

Once you’ve established your content hierarchy, it becomes much easier to determine which magnet size will work.

This approach is generally better than choosing a large magnet first and then trying to fill the available space

Size can influence the overall cost of your order, along with factors such as quantity, shape, finishing and production requirements.

If you are ordering magnets for a large marketing campaign, choosing the most appropriate size can help you balance visibility, functionality and budget.

For many Australian small businesses, the best option isn’t necessarily the cheapest or largest magnet. It’s the format that provides enough space to communicate the information customers actually need.

If you’re ordering in bulk, compare the available sizes and quantities before making your decision.

There isn’t one universally perfect business card magnet size.

A local plumber may need a clear, practical contact magnet.

A real estate agent may prioritise branding.

A café may want a compact promotional magnet.

A construction company may need a larger format to communicate several services.

Your industry, design and marketing objective should determine the size.

Once you’ve decided what information your customers need, choosing the right format becomes much easier.

Choose from different sizes, shapes and designs to create practical promotional magnets for your Australian business.

Ready to create your business card magnets?

There isn’t one universal size for business card magnets. Options vary depending on the design and purpose, from compact square formats to larger rectangular and custom-shaped magnets.

A medium or larger format can be useful for tradies because it provides enough space for a business name, phone number, website and key services while keeping the information readable.

Not necessarily. A larger magnet is useful when you genuinely need more design space, but a smaller magnet can be more effective when the design is simple and focused.

Yes. A QR code can direct customers to a website, booking page, quote form or other online destination. It should be large and clear enough to scan easily.

Yes. Custom-shaped magnets can be used when a business wants a distinctive shape that supports its branding or industry.

Start by deciding what information you need to display. If you only need a logo and basic contact details, a compact format may be enough. If you need services, a QR code or additional information, consider a medium or larger format.
