Punctuation marks

Punctuation is essential for clear writing. It guides the reader, creates pauses, and adds emphasis.

Punctuation follows grammar rules, not spoken language. Correct usage helps structure the text and makes it easier to read.

Multiplication Sign

Use the multiplication sign ( × ) to indicate multiplication or to express dimensions. The space can be omitted if there are only numbers on both sides.

Win: alt + 0 2 1 5

Example (good): 1024 × 768 pixels

Example (poor): 1024 X 768 pixels

---

En dash

An en dash ( – ) should be used in all time period expressions.

Mac: option + - Win: alt + 0 1 5 0

---

Example (good): 28.1. – 12.3.

Example (poor): 28.1.-12.3.

---

Example (good): 7.30 – 8.15

Example (poor): 7.30-8.15

Ellipsis

Use ellipsis ( … ) to express a continuation in lists or sequences. Ellipsis is an alternative for situations where an en dash would be insufficient.

Mac: option + ; Win: alt + 0 1 3 3

Example (good): -2…+2 °C

Example (poor): -2–+2 °C

Time format

Use a period ( . ) to separate minutes from hours.
