Mirror image of text

“Mirror image of a word” is asked two ways, and the answers differ. A mirror image is what you see with a mirror stood upright beside the word: left and right swap, so the word reads backwards and each letter is reversed, while top and bottom stay put. A water image is the word reflected in water lying below it: top and bottom swap, the letters stay in order, and each one is upside down. Do both and you have turned the word half way round.

What makes these questions answerable is that some letters do not change. Letters symmetric about an upright line — A, H, I, M, O, T, U, V, W, X, Y — look the same in a mirror; letters symmetric about a level line — B, C, D, E, H, I, K, O, X — look the same in water. The page highlights them for the reflection you choose. They depend on the typeface, so it is always named: a serif or an italic can make a symmetric letter lopsided.

The same tool makes mirror lettering for real jobs: text applied inside a window to be read from outside, a tattoo stencil, a message to be read in a rear-view mirror. And for ambulances in India, the AMBULANCE preset sets the front marking the way AIS-125 describes it — reversed, at a 7 : 1 length-to-height ratio, at a width you give in millimetres (ARAI copy of AIS-125).

1. 1Type the text. A word, a name, a number or a single letter. It is set in the typeface you choose — which matters, because serifs and slants change what is symmetric.
2. 2Choose mirror or water. Mirror image: a mirror stood to the right, left and right swap. Water image: water below, top and bottom swap. Both: a half turn.
3. 3See what stays the same. The row of letters under the panes highlights the ones that look the same after this reflection — the letters reasoning questions are built on.
4. 4Save or practise. Download PNG, JPEG or an SVG with editable text; or try the practice question below the tool.

“AMBULANCE” with the vehicle preset, 550 mm wide at 100 dpi, is written as a 2165 × 309 px PNG: 550 mm is 21.65 inches, 2165 pixels at 100 per inch, and 2165 ÷ 7 = 309. The lettering is stretched so its box is exactly seven times as long as it is tall, reversed left to right, red on yellow. As an SVG, the same drawing is given a width of 550 mm and the height follows at 78.5 mm. For practice, the water image of “CODE” keeps C, D, E and O looking the same in a plain sans serif, so every letter of it is its own water image.

• Symmetry depends on the font. The highlighted letters are right for a plain sans serif; another typeface can disagree.
• The preset is a layout aid. AIS-125 governs size and placement on the vehicle; check the current standard and your RTO.
• SVG text needs its font. The SVG keeps editable text, so the typeface must be installed where it is opened. Outline it before cutting.
• One line of text. Paragraphs and line breaks are not laid out; type one line at a time.

What is a water image?

The reflection of a word in water lying below it: top and bottom swap, left and right do not. In a water image of "SKETCH", the letters stay in the same order and each one is upside down — B, C, D, E, H, I, K, O and X look unchanged in a plain typeface.

Which letters look the same in a mirror?

In a plain sans serif, A, H, I, M, O, T, U, V, W, X and Y, and the digits 0 and 8, look the same when a mirror is stood beside them. Lower case is less reliable — b and d swap, and many fonts break the symmetry of o, v and w — which is why exam questions use capitals.

Why does the font matter?

Symmetry is a property of the drawn letter, not the alphabet. A serif on one side of an A, a slanted italic, or a spur on a G makes a letter that looked symmetric in one font change in another. The page names the font next to the answer for that reason.

Is the AMBULANCE preset official?

It follows AIS-125: the front marking reads in mirror image so drivers ahead can read it in their mirrors, with letters at a 7 : 1 length-to-height ratio, and Type B at least 550 mm wide. It is a layout aid, not certification — check the current standard and your RTO.

Can I use the SVG for a vinyl cutter or sign maker?

Yes. The SVG keeps the text as text under a reflecting transform and can be given a physical width in millimetres. Because it is text, the typeface must be installed wherever it is opened; outline the text in your design app before cutting.
