The size of a fridge magnet decides what it can do. A small magnet keeps your number handy. A larger one can hold a full-year calendar or a notepad. Getting the size right means your design has room to breathe and your magnet has a clear job on the fridge. Here's a practical guide to the sizes and shapes in the Green Magnets range.
Start with what the magnet needs to hold
Before you look at dimensions, decide what goes on the magnet. A logo, name and phone number need far less space than twelve months of dates. Write down the content first, then choose the smallest size that shows it clearly. Cramming a lot onto a small magnet makes it harder to read, and a magnet that's hard to read is easy to ignore.
Business card magnets (54 x 90 mm)
The classic. A business card magnet is the same size as a standard business card, with round or square corners. It suits a logo, your name, a phone number and perhaps one line about what you do.
The business card range also includes a few close relatives:
- Small rectangles at 50 x 70 mm for a compact, simple design.
- A house business card at 54 x 90 mm, popular with property businesses.
- An extra long business card at 60 x 120 mm when you need a little more width.
These are easy to slip into an envelope with a letter or invoice. Browse the business card magnets collection.
A7 magnets (70 x 100 mm)
An A7 magnet gives you noticeably more room than a business card without becoming large. It's a good middle ground for contact details plus a short list of services, opening hours or a handful of key numbers.
A6 magnets (105 x 148 mm)
A6 is roughly postcard size and a very versatile format. There's room for a compact year calendar, an emergency contact list or a kitchen conversion chart, with your branding alongside.
Choose an A6 rectangle with round corners or square corners. Related options include the A6 house shape at 100 x 145 mm and the A6 notepad holder at 100 x 142 mm, available with or without a generic notepad.
DL magnets (210 x 97 mm)
DL is tall and slim, with the same proportions as a DL flyer. That shape suits a year planner laid out in a column, a long list of numbers, or a design that runs top to bottom. It also fits naturally into DL envelopes for mail-outs.
The DL rectangle comes with round or square corners, and there are DL house shapes too: a landscape house at 97 x 208 mm, a portrait house at 97 x 204 mm and a DL house portrait at 210 x 97 mm.
A5 magnets (148 x 210 mm)
A5 is a generous size for content-rich designs: a full calendar with space for notes, a takeaway menu, or a detailed reference chart. It comes with round or square corners. There's also an A5 photo frame magnet at 210 x 148.5 mm, and an A4 magnet at 210 x 294 mm when you need a full page.
When to go beyond a rectangle
Shape can do some of the talking before anyone reads a word.
House shapes
House shaped magnets range from mini sizes at 50 x 60 mm and 50 x 75 mm, through 70 x 80 mm, up to A6 and DL. They're a natural fit for real estate agents, builders, property managers and home services. There are house notepad holders too, at 90 x 110 mm and 141 x 60 mm.
Squares, circles and ovals
Squares come in 50, 60, 80, 90 and 95 mm. Circles come in 50, 64, 80 and 90 mm, and there's a 62 x 87 mm oval. These suit logo-led designs, badges, and a simple message with a phone number.
Die-cut shapes
Die-cut shapes make your industry obvious at a glance: a van (46 x 90 mm), a van with a ladder (48 x 90 mm), a truck (50 x 85 mm), a car (83 x 210 mm), a tooth (50 x 70 mm), an apple (56 x 60 mm) and a shoe (40 x 70 mm).
Practical formats
Notepad holders come in 80 x 95 mm as well as the house and A6 options above. There's also a 20 cm ruler magnet at 210 x 50 mm, and a photo frame magnet at 135 x 185 mm.

Other things to weigh up
Think about how the magnet will reach people. If it's going in an envelope, check it fits. If it's a letterbox drop, a flat magnet that won't bend is easy to handle. Consider the fridge, too: a modest size is more likely to find space among family photos and school notes.

Frequently asked questions
What size is a business card magnet?
54 x 90 mm, the same as a standard business card. It comes with round or square corners, and there's a house-shaped version in the same size.
Which size suits a calendar?
DL (210 x 97 mm), A6 (105 x 148 mm) and A5 (148 x 210 mm) all work well, as do the A6 and DL house shapes. A5 gives the most room for notes; DL suits a column-style year planner.
Can I see the exact shape before I design?
Yes. Each product page has a PDF print template you can download. Or choose free artwork and our designer will set everything up for you.
Round corners or square corners?
It's mostly a matter of style. Round corners give a softer, friendlier look, while square corners feel crisp and formal. Many rectangle sizes are available both ways.
