Refrigerator Magnet Sizes and How to Put Each One to Work
A fridge magnet keeps your brand in the home for months. Here are the five best sizes, what each is for, and how to design one people actually keep on the fridge.
The five best fridge magnet sizes are 2 x 3.5 business card, 3.5 x 4 medium, 4 x 6 postcard, 5 x 7 large, and a 3 inch round die-cut. The small size is the everyday handout, the mid sizes carry a calendar or coupon people keep, the large size becomes the household reference, and the round shape stands out on a crowded fridge.

Why refrigerator magnets work for marketing
A refrigerator magnet earns something almost no other ad can: constant, repeated exposure inside the home. Because it sticks to a surface the whole household visits many times a day, your name and number stay in view for months, instead of vanishing like a scrolled ad or a discarded flyer. Every trip to the fridge is another impression.
Magnets are also genuinely useful, so people keep them. A magnet that carries a calendar, a phone number, or a schedule becomes the default reference the moment someone in the house needs your service. That is the quiet power of the format: it turns a promotional piece into a household tool.
Put those together, long life, daily visibility, and real utility, and a custom magnet delivers strong value per piece over its life. The rest of this guide covers the five sizes that do this best and how to design each one. Explore the full lineup in our magnet collection.
The top 5 magnet sizes
Five sizes cover almost every promotional need. The 2 x 3.5 inch business card magnet is the everyday workhorse, cheap in volume and easy to hand out with every order. The 3.5 x 4 inch medium gives you room for a small calendar or coupon while staying compact.
The 4 x 6 inch postcard magnet is the classic mailer and photo size, big enough for a full calendar, a menu, or a save-the-date the household keeps. The 5 x 7 inch large magnet becomes the household reference, fitting an emergency-number list, a sports schedule, or a large calendar that earns a spot all year.
Finally, a 3 inch round die-cut magnet stands out with a bold shape on a crowded fridge, perfect for a strong logo or a promo badge. The reference table below lines up all five with their dimensions and best use, and the diagram above shows them to scale. Our business card magnets cover the smallest and most-handed-out of the set.
What each size is for
Match the size to the job. The business card magnet is for handouts: include one with every order, invoice, or appointment card so your number ends up on the fridge without any extra effort. It is the size you order by the thousand.
The medium and postcard sizes are for keepers. Build a calendar, a coupon, or a menu onto a 4 x 6, and the household has a reason to leave it up for a full year. Real estate agents, restaurants, and service businesses lean on this size for exactly that reason. A car magnet extends the same idea to the vehicle for on-the-road exposure.
The large 5 x 7 is the reference piece, the one that becomes the household's go-to for emergency numbers or a sports schedule and quietly keeps your brand in the center of the kitchen. The round die-cut is your standout play, used when shape and a bold mark matter more than dense information.
What size fridge magnet should you pick
Pick by what the magnet has to hold. A photo magnet needs 4 by 6 inches so the image reads from across the kitchen. A business magnet only needs 2 by 3.5 inches because the phone number is the whole message. A save the date needs 4 by 6 or 5 by 7 inches so names, date and city all sit at readable size.
Design tips for each magnet size
Design for a glance from across the kitchen. Lead with large, legible contact information and one clear call to action, keep the layout uncluttered, and use a single strong brand mark rather than a busy collage. On the small business card size especially, less is more: name, number, and one message.
On the larger sizes, earn the space with utility. A calendar, a service schedule, a conversion chart, or an emergency-number list gives the magnet a daily job and a reason to stay up. Size the type so the useful part reads easily, and let your brand frame it rather than crowd it.
Technically, the rules are the same across sizes: build in CMYK for true color, add bleed past the trim, and keep text inside a safe margin so nothing important gets cut. For a die-cut round or custom shape, account for the cut line so no key element sits on the edge. Our online design tool sets up the bleed and safe margins for each size, and our bleed and trim guide covers the details.
Order custom magnets
Once you have picked a size and laid out the design, ordering is simple. Choose square corners for a classic, budget-friendly look or a die-cut round for standout shape, set your quantity, and order enough to include a magnet with every transaction and still stock the counter. The per-piece price drops as the run climbs, so volume pays off.
Every magnet prints in full color on durable magnetic stock that holds firmly to any steel surface, from the fridge to a filing cabinet. Because each piece delivers months of exposure, even the larger reference sizes tend to be cost effective over their life.

Common Questions
Common questions about fridge magnet sizes
What is the standard fridge magnet size?
The standard fridge magnet size is 2 by 3.5 inches, the business card footprint used for handouts and service reminders. The other four common sizes are 3.5 by 4, 4 by 6, 5 by 7 inches and a 3 inch round die-cut.
What are the best refrigerator magnet sizes for marketing?
Five sizes cover almost every promotional need. The 2 x 3.5 inch business card magnet is the everyday workhorse for handouts. The 3.5 x 4 inch medium size fits a small calendar or coupon. The 4 x 6 inch postcard size is the classic mailer and photo magnet. The 5 x 7 inch large size becomes the household reference for a calendar or emergency numbers. And a 3 inch round die-cut magnet stands out with a bold shape. Choose the size by the job you want the magnet to do, from a quick handout to a keep-all-year reference.
Why do refrigerator magnets work so well for marketing?
A fridge magnet earns something most advertising cannot: constant, repeated exposure in the home. Because it sticks to a surface the whole household visits many times a day, your name and number stay in view for months instead of vanishing like a scrolled ad or a discarded flyer. Magnets are also genuinely useful, so people keep them, and a useful magnet with a calendar or a phone number becomes the default reference when someone needs your service. That combination of long life, daily visibility, and practical value is why magnets deliver strong long-term value per piece.
What is each fridge magnet size best used for?
The 2 x 3.5 inch business card magnet is ideal for handouts with every order or invoice. The 3.5 x 4 inch size suits a compact calendar, a coupon, or a short service list. The 4 x 6 inch postcard magnet is big enough for a full calendar, a menu, or a save-the-date, which makes it a favorite for mailers. The 5 x 7 inch large magnet works as a household reference for emergency numbers or a sports schedule. And a 3 inch round die-cut magnet is best when you want a distinctive shape and a bold logo to stand out on a crowded fridge.
How do I design a fridge magnet that people keep?
Design for a glance from across the kitchen and give the magnet a reason to stay up. Lead with large, legible contact information and one clear call to action, keep the layout uncluttered, and use a single strong brand mark rather than a busy collage. Then add utility: a calendar, a service schedule, a conversion chart, or an emergency-number list gives the magnet a daily job. Technically, build in CMYK for true color, add bleed past the trim, keep text inside a safe margin, and account for the shape if you choose a die-cut.
How do I choose the right magnet size and shape?
Start from how the magnet will be distributed and used. For handouts you will give with every transaction, the compact business card size is economical and easy to carry. For a piece you want the household to keep and reference, step up to a postcard or large size and build in a calendar or schedule. Choose square corners for a classic, budget-friendly look, or a die-cut round or custom shape when you want to stand out on a busy fridge. Our magnet product pages let you set size, shape, and quantity with live pricing.
What do custom fridge magnets cost and how are prices set?
Price scales with size, shape, finish, and quantity, and it updates live in the configurator as you choose. Smaller business card magnets are the most economical per piece and get cheaper in larger runs, which makes them ideal to hand out in volume, while larger reference magnets and die-cut shapes cost a bit more each. Because magnets deliver months of exposure per piece, even the larger sizes tend to be cost effective over their life. Set the size and quantity you need and the per-magnet price drops as the run climbs.
