# CE Marking Label Rules: Size, Placement, and What Not to Do

The CE mark is one of the most recognised symbols in product compliance, but it comes with strict rules on size, placement, proportions, and who gets to use it. Getting these details wrong can trigger market surveillance action even when your product is technically compliant. This short covers every labelling requirement you need to know.

### Why the label matters

The CE mark looks simple — two letters, a clean logo. But the rules around how you apply it are surprisingly specific, and getting them wrong is one of the easiest ways to attract market surveillance attention. Let's go through exactly what the regulations require.

### The labelling requirements

The CE mark's minimum height is five millimetres, proportions fixed. Place it on the product first; packaging only if impractical. A Notified Body's four-digit number follows the mark. Use one mark under multiple directives — never on non-CE products.

### The most common label mistakes

Common labelling mistakes: a CE mark that's too small, placing it only on the box instead of the device, and omitting the Notified Body number when one applies. Run a quick label audit before shipping — a ten-minute check that can prevent a costly recall.
