# Page weight budget Page weight represents the amount of data transferred to access the web page (based only on HTTP requests). In short, the bigger the number, the more carbon emissions. It is recommended to keep this metric as low as possible so setting a page weight budget can help you stay on top of this. As mentioned in the [Web Almanac](https://almanac.httparchive.org/en/2022/sustainability#page-weight), 1 MB should be a maximum when you get started, with 500 kB as the ultimate threshold. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.umbraco.com/sustainability-best-practices/frontend/page-weight-budgets.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
