# Why does AI ignore my word count or length instructions?



## Answers

### Answer by Agnieszka Wozniak

You ask for a 300-word article and get 550 words. You ask for a short reply and receive four paragraphs. Length problems are one of the most common frustrations with AI writing.

Why does it happen?

1. AI does not count words while writing. Language models generate text piece by piece and do not keep an exact running word count. They estimate length based on patterns, which is approximate.\
2. Tokens are not words. Models work in tokens, pieces of words, which makes exact word counting even harder.\
3. Training tends toward thoroughness. Many models have been trained to give complete, detailed answers, so they lean long.\
4. Conflicting instructions. If you ask for "a detailed explanation covering all aspects" in 100 words, the content requirement usually wins.\
5. Long prompts and examples can encourage long outputs.

Techniques that work:

Use structure instead of word counts. "Write 3 paragraphs of 3 to 4 sentences each" or "give exactly 5 bullet points of one sentence each" is easier for AI to follow than "write 200 words."

Give a range. "Between 250 and 300 words" is easier to hit than an exact number.

Explain why. "Keep it under 100 words because it will be posted as a WhatsApp message" helps the AI prioritise brevity.

Ask it to check and revise. After the draft, say "Count the words and trim this to under 300 words." Tools that can run code can count accurately.

Cut by percentage. "Shorten this by 30 percent without losing key points" works well.

Show a sample of the right length. AI often imitates the length of examples.

Use a word counter. For strict limits, such as exam answers, applications or meta descriptions, paste the result into a word counter or ask an AI that can run code to count it.

Set default preferences. In custom instructions, add "Keep responses concise unless I ask for detail."

For very long content, such as a 3,000-word report, the opposite problem can occur: the AI produces less than requested. Ask for an outline first, then generate each section separately with its own target length.

Length control is ultimately an editing step. Treat AI output as a draft, and expect to trim or expand it slightly to meet strict limits.
