Misplaced spaces can confuse your audience and give a bad impression.
While writing, follow these rules:
- Insert a space between numbers and units of measure, except when the unit of measure in question is visualised by a superscripted sign, such as ° (degree), ' (foot) and " (inch), in which case you should omit the spacing. Product naming is another exception, where no space is needed between the number and unit of measure.
- Insert a space before and after a phrase from another language.
- Insert a blank line between two paragraphs.
For example, don't say:
- As a desktop 3D printer, F250 offers a 320 × 350 × 220mm work area.
- The module stops working automatically whenever its temperature sensor detects a higher than normal (one that exceeds 55 ℃/131 ℉) working temperature.
- Bring them to life now with the right tool: the 10 W High Power Laser Module.
- This inevitably gives rise to what we call知之者胜，不知之者不胜in Chinese.

Pay close attention to the spacing between words when they are connected by punctuation marks. Generally, insert one space after a punctuation mark, except for the following cases where you should put:
- No space adjacent to the slash or hyphen.
- One space before the opening bracket, and none between the closing bracket, if the sentence ends with parenthesis.
- One space before and after the ampersand.
- One space before and after the multiplication sign.
Should you need to use Chinese Pinyin, don't put spacing within the pinyin.
