Why some businesses put their card on a magnet
A paper business card has a short working life. It goes into a wallet or a drawer, and most of the time it is found again only when someone clears that drawer out. A magnetic business card has a different job. It goes on the fridge, the filing cabinet or the side of a metal desk, and it stays in view for months. For a plumber, an electrician, a pizza place, a pet groomer, a tuition centre or a clinic that people call again and again, that is the whole point.
Magnet cards look simple, but they are not a normal card with a magnet glued on the back. The thickness of the magnetic sheet, the size, the print surface and the way the card is cut all decide whether it holds firmly to the door or slides down to the floor the first time someone slams the fridge. This guide goes through those decisions so you can order magnet cards that actually stay up.
How a business card magnet is made
Most business card magnets are built from two layers. The bottom layer is flexible magnetic sheeting, a rubbery material filled with magnetic powder. The top layer is the printed surface. There are two common ways of putting them together:
- Printed paper laminated to magnetic sheet. The design is printed on paper or thin card, usually with a gloss or matte laminate for protection, and then mounted onto the magnetic backing before cutting. This gives the sharpest print and the widest choice of finishes.
- Direct print onto white-faced magnet. Some magnetic sheeting comes with a white vinyl or paper face that can go straight through a suitable printer. It saves a step and suits short runs, but the colour range and finish options are narrower.
Both methods work. If your design has a lot of solid colour, a photo or fine text, the laminated paper route usually looks better. If you need a small quantity quickly and the design is simple, a direct print can be the practical choice.
Thickness: the number that decides whether it stays up
Magnetic sheet is sold by thickness, usually given in mil (thousandths of an inch) or in millimetres. For business card magnets you will mostly see something in the range of 15 to 30 mil, roughly 0.4 to 0.76 mm.
Thin magnets
Thinner sheet is lighter, cheaper to post and fine for a card that will sit on a flat, clean fridge door. The pull is weaker, though. On a textured fridge surface, a stainless steel door with a coating, or a door that gets opened hard, a thin card can slip or drop.
Thicker magnets
Thicker sheet holds harder and feels more substantial in the hand. It is the safer choice for anything that will live on a work van, a metal cabinet in a busy kitchen or a filing drawer that is opened all day. It also resists bending, so the corners stay flat for longer.
A useful test before a full order: ask for a sample of the magnetic stock and try it on the kind of surface your customers have. Many modern fridges have panels or finishes that magnets do not grip as well as old enamel doors did, and that difference shows up in a few seconds of testing.
Size and shape
Most magnet cards are cut to standard business card size so they can be designed from the same template as your paper cards. That has a real advantage: you can keep your layout, fonts and colours consistent across both. If you are not sure what fits on a standard card, our guide to what to print on the back of a business card covers how to split information between two sides, and the same thinking applies to a magnet, which only has one printed side.
That single side is the main design difference. On a paper card the back can carry opening hours, a map or a QR code. On a magnet the back is the magnetic layer, so everything has to fit on the front. Plan for it early:
- Keep the name of the business and the phone number large. The card will be read from a step or two away, not held in the hand.
- Choose one main call to action, such as a phone number or a booking link, and make it the most visible element.
- Drop secondary details that people will not need when they reach for the fridge, such as a full postal address if customers never visit you.
- If you add a QR code, keep it on a plain light box and test it on the printed proof.
Rounded corners are worth considering. A square corner on a thick magnet can catch on a sleeve or a cloth and lift the card off the door. A small radius on all four corners makes it harder to knock off and looks tidier after months of use.
Custom shapes
A magnet cut into a house, a tooth, a slice of pizza or a paw print gets attention and is often kept longer. Custom shapes need a cutting die or a digital cutter path, which adds set-up. Keep any thin parts of the shape wide enough to survive handling, and keep text well inside the cut line so it does not end up on a curve.
Print and finish choices
The surface of a fridge magnet gets touched with wet and greasy fingers, wiped with cloths and splashed in a kitchen. A finish that protects the print matters more here than on a paper card that lives in a wallet.
| Finish | What it does | Good for |
|---|---|---|
| Gloss laminate | Bright colours, easy to wipe clean | Photos, food businesses, bold colour designs |
| Matte laminate | Softer look, less glare under kitchen lights | Clinics, professional services, text-heavy cards |
| No laminate | Lower cost, print exposed to wear | Short promotions or event giveaways |
For the design file, the usual business card rules still apply: add bleed, keep text inside the safe zone and use enough contrast. Dark backgrounds on magnets need the same care as on paper, and the advice in our article on black and dark business cards about rich black and reversed text carries over directly.
Who gets the most from a magnet card
A magnet card costs more per piece than a paper card, so it makes sense where people are likely to call you again. Typical examples:
- Home services: plumbers, electricians, aircon servicing, pest control, locksmiths. The customer needs you again in six months and wants the number to hand.
- Food delivery and takeaway: a magnet with the menu link or order number stays where hungry people look.
- Health and care: clinics, dentists, physiotherapists and vets, especially when combined with a space for the next appointment.
- Education: tuition centres and music schools that parents contact every term.
- Property: agents who want to stay in front of homeowners until they decide to sell.
For a one-off networking event, a standard paper card is usually the better buy. Many businesses order both: paper cards for meetings and a smaller run of magnets to leave behind after a job is done.
Handing them out and posting them
Magnet cards stick to each other and to anything metal, which affects how you store and send them. A few practical points:
- Keep them in their box until they are used. Loose magnets in a bag full of keys pick up scratches.
- Do not store them next to bank cards with a magnetic stripe, hotel key cards or older hard drives.
- If you are mailing them in envelopes, check the weight. A magnet is heavier than a paper card and can push a letter into a higher postage band.
- In very hot cars the magnetic layer can soften and warp, so do not leave the box on a dashboard for days.
Ordering business card magnets with us
We print magnet cards alongside our standard business card printing, so you can match the design to your paper cards and order both in one go. When you send your file, tell us where the magnets will be used, such as a fridge, a van or a metal cabinet, and we will suggest a magnetic thickness and finish that suits it. If you are unsure about the layout, we can send a proof showing exactly where the cut line and safe area fall before anything is printed.
If you want to try the stock first, ask for a sample and put it on your own fridge for a week. That is the most honest test there is. When you are ready, get in touch with our team with the quantity, size and finish you have in mind, and we will come back with a quote and a turnaround time.
