Precisely control AI output length with proven techniques for both brief and comprehensive responses.
## ROLE
You are an output length optimization specialist who engineers prompts to produce precisely sized responses.
## OBJECTIVE
Add precise length control to my prompt to get outputs of the exact size I need.
## CURRENT PROMPT
{{YOUR_PROMPT}}
## DESIRED LENGTH
{{TARGET_LENGTH}} (e.g., "3 sentences", "500 words", "1 paragraph")
## LENGTH CONTROL FRAMEWORK
**1. Length Specification Methods**
**Exact Count**:
```
Respond in exactly [N] sentences.
Your response must be [N] words (+/- 10%).
Provide exactly [N] bullet points.
```
**Range Specification**:
```
Keep your response between [min] and [max] words.
Answer in [N] to [M] paragraphs.
```
**Relative Sizing**:
```
Brief response (2-3 sentences max).
Comprehensive analysis (minimum 500 words).
Executive summary (one paragraph).
```
**2. Length Enforcement Techniques**
**Hard Constraints**:
```
CRITICAL: Do not exceed [N] words under any circumstances.
If you reach [N] words, stop and summarize remaining points.
```
**Quality-Length Balance**:
```
Prioritize completeness over brevity, but stay under [N] words.
Be concise, but ensure all key points are covered.
```
**3. Section-Level Control**
```
Structure your response as:
- Introduction (1 sentence)
- Main Points (3-5 bullet points, max 20 words each)
- Conclusion (1 sentence)
```
**4. Length Verification Prompt**
```
After writing, verify your response meets length requirements:
- Target: [length specification]
- Actual: [count your output]
- If over: trim least essential content
- If under: add relevant detail
```
**5. Length Templates**

| Profile | Specification | Use Case |
|---------|---------------|----------|
| Tweet | Max 280 chars | Social sharing |
| TL;DR | 2-3 sentences | Quick summary |
| Brief | 100-150 words | Email responses |
| Standard | 250-400 words | Blog sections |
| Detailed | 500-800 words | Full articles |
| Comprehensive | 1000+ words | In-depth analysis |
