Why Refrigerator Magnets Are Used for Marketing and Promotions

♦ Constant Brand Exposure

Refrigerator magnets offer daily brand visibility by sticking around—literally. Unlike digital ads that come and go, magnets stay put for years, keeping your brand top of mind.

xample: A plumbing company’s magnet stays on the fridge, so when an emergency happens, the customer calls them instead of searching online.

♦ Practical & Useful

Magnets do more than promote—they’re useful for holding grocery lists, reminders, and notes. Some businesses take it further with interactive designs like dry-erase boards or takeout menus customers can actually use.

Example: A pizza place gives out fridge magnets with their menu and phone number, making ordering easy.

♦ Long Lifespan = Higher ROI

Magnets last longer than paper flyers and are more affordable than digital ads. Remember all the magnets on the fridge of your parents’ house? They’re designed with longevity in mind.

Example: A dentist’s office gives patients appointment reminder magnets instead of paper cards, ensuring their contact info stays visible.

♦ Targeted Marketing

Magnets can be customized for any industry. Realtors use photo frame magnets, car repair shops hand out oil change reminder magnets, and non-profits distribute fundraising magnets. It’s all about customizing to your specific target market.

Example: A pet grooming service gives out paw-shaped magnets with their phone number and a reminder to schedule grooming every three months.

♦ Great for Giveaways

Magnets are perfect promotional items for trade shows, networking events, and direct mail. People appreciate useful freebies—and businesses benefit by staying top-of-mind long after the event ends.

Example: A real estate agent mails branded calendar magnets to past clients so they know who to call when they need to buy, sell, or refer.

imple Design Tips for Each Ref Magnet Size

♦ 2″ x 3.5″ (Business Card Size)

  1. Keep it simple – focus on the name, contact info, and logo.
  2. Use high-contrast colors to make text easy to read.
  3. Consider adding a QR code for your website or social media.
  4. Glossy or matte finishes can enhance the look and feel and make it stand out.

♦ 3″ x 3″ (Square)

  1. Use bold typography—this size is great for quotes or key info. Keep the text to a minimum, though.
  2. Add a clean border to give a polished look.
  3. Make it interactive with a scannable QR code.
  4. Works well for colorful, attention-grabbing designs.

♦ 3″ x 4″ (Portrait or Landscape)

  1. Utilize both horizontal and vertical layouts, depending on content.
  2. Include high-quality images for maximum impact.
  3. Ensure the font is large enough to be legible, even from afar.
  4. Add icons to make key details stand out such as contact details, website, and social media links.

♦ 4″ x 6″ (Postcard Size)

  1. High-quality images make this size pop—use sharp, high-resolution photos.
  2. Avoid too much text—stick to the essentials.
  3. Use hierarchy in the design (bold headlines, subtext, and a CTA).
  4. Don’t overcrowd the design. Make sure the background doesn’t overpower the main message.

♦ 5″ x 7″ (Large Format)

  1. Prioritize readability—stick to minimal text, large fonts, and simple layouts.
  2. Consider using negative space to avoid a cluttered look.
  3. Great for calendars, so choose a grid layout if applicable.
  4. Use bold CTAs like “Call Now” or “Visit Our Website” for high visibility.

TIP: No matter the size, always use strong magnets that stick around—people won’t keep flimsy ones!
