Quick Answer
Target an 8th-10th grade reading level for technical writing, with a Flesch Reading Ease score of 50-60. Use clear structure even when terminology is complex.
Explanation
Technical writing serves readers who need to understand and act on information. Clarity directly impacts whether users can follow instructions, troubleshoot problems, and use products effectively.
Technical terms are necessary when they're the precise names for concepts—don't avoid them. However, define terms on first use, and keep the sentence structure around those terms simple.
User documentation should be especially clear. People reading help docs are often frustrated or confused. Simple, step-by-step instructions reduce support tickets and improve user satisfaction.
API documentation and developer guides can use higher-level technical language because readers have specialized knowledge. But even expert readers appreciate concise, well-organized content.
Examples

| User guides | 7th-8th grade |
| Help documentation | 7th-8th grade |
| Technical tutorials | 8th-9th grade |
| Developer docs | 9th-10th grade |
| API references | 10th-11th grade |

Frequently Asked Questions
Can technical writing be too simple?
Rarely. The main risk is omitting necessary technical terms or oversimplifying to the point of inaccuracy. But simple sentence structure around technical terms improves comprehension.
How do I explain complex processes simply?
Break processes into numbered steps. Use one action per step. Lead with the verb. 'Click Settings' is clearer than 'Navigate to the Settings menu by clicking on it.'
Should I avoid jargon?
Use jargon when it's the precise term your audience knows. Avoid jargon when simpler words work. 'Start' is better than 'instantiate' unless instantiation is specifically what you mean.
