A true mirror image

Mirror writing is writing you can only read in a mirror: every letter is reversed and the line runs from right to left. The generator really mirrors the lettering – it does not use look-alike characters from foreign alphabets, which often print wrongly. So mirror writing prints cleanly on any printer.

Horizontal or vertical

The default is horizontal mirroring (left ↔ right), like writing in front of a mirror on the wall. The vertical variant (top ↕ bottom) turns the letters upside down – the mirror then lies flat under the sheet. Both can be chosen in the settings.

How to read mirror writing

  • Stand a hand mirror upright next to the text and look at the reflection.
  • Turn the sheet over and hold it against a window – the writing shows through.
  • With a little practice: just read it. Many children can do this surprisingly quickly.

No key needed

Unlike symbols or number code there is no table here. Instead, the sheet shows a hint below the cut line on how to make the text readable. For a harder puzzle, combine mirror writing with the Caesar code: shift first, then mirror.

FAQ

Frequently asked questions

Why can’t I copy the mirror writing as text?

Because it is a true mirror image, not Unicode look-alike characters. It prints cleanly and looks like handwritten mirror writing – but it cannot be copied as text.

How do I read mirror writing without a mirror?

Turn the sheet over and hold it against the light, or read it from the back through the paper.

Did Leonardo da Vinci really write in mirror writing?

Yes, in many of his notebooks. As a left-hander he avoided smudging the ink – and curious readers had a harder time.
