Size Questions

What is the most popular custom magnet size?
The 2" x 3.5" business card magnet is Canada's most-ordered size — it matches a standard business card exactly. For promotional handouts, 2" x 2" squares and 2.25" round buttons are the next most common.
What size magnet should I choose for a save-the-date?
4" x 6" is the sweet spot: room for an engagement photo, standard postcard proportions, and light enough to mail in a normal invitation envelope.
How thick are custom magnets?
Our flat magnets print on 20 pt (about 0.5 mm) flexible magnet stock — thin enough to mail, strong enough to hold paper to the fridge. Car magnets use a thicker vehicle-grade stock.
