How thick are your custom magnets?

Our custom magnets have a thickness of about 0.38 mm, or 15 mils (1 mil = 0.001 inches). For reference, this is about the same thickness as our die cut stickers with the backing on.

Our acrylic magnets have a thickness of about 4 mm, or 158 mils, including the magnet itself.

Keep in mind that magnet thickness does not necessarily correlate with magnet strength. The strength of a magnet primarily depends on the quality of the raw materials and the manufacturing process.
