What is Prompt Size Calculator?

The Prompt Size Calculator is a tool that helps you estimate how large your text prompt is in terms of tokens and words. Since many AI models charge or process input based on token count rather than character count, this tool makes it easier to understand how much of your input is being used. It is especially useful for preparing prompts efficiently, managing token limits, and budgeting AI usage.

How to Use:

1. Enter Character Count: Input the total number of characters in your prompt.
2. Enter Average Characters per Token: Provide the approximate number of characters per token (commonly around 4).
3. Click “Calculate”: The tool will estimate the number of tokens and words based on your input.
4. Review Results: Use the output to optimize prompt size, control token usage, and plan requests more effectively.
