| Where you might paste it | Typical room | Fit |
|---|---|---|
| Small custom-instruction boxes (per field) | ~1,500 chars | |
| Typical project/gem/bot instruction fields | ~8,000 chars | |
| Long-context system prompts | 30,000+ chars |
Token estimate uses the common ~4 characters/token rule of thumb; real tokenizers vary by model. Field limits are typical values, not guarantees, platforms change them.
This is why profiles come in three sizes: Compact is built for the small boxes, Standard for project fields, Full for platforms that take long instructions. Get yours →
