How to find it on the ruler
The blue band runs from zero to this mark. If it passes the screen, scroll the horizontal ruler. A narrow phone does not shrink the scale; the mark simply sits further along. The left ruler stays fixed as soon as the page opens.
- 1. Find the 0 mark at the top of the left ruler. Rest one edge of the object on that line.
- 2. The long blue marks are centimetres. Ten short gaps sit between them, and each gap is 1 millimetre.
- 3. Go to the long mark labelled 2, then count 5.11 millimetres further.
- 4. Match a bank card once so this screen shows a real centimetre. Keep the browser zoom at 100%.
