Do headers go on the left or right side of paper?

Headers typically go at the top of the paper, centered or aligned to the left. There's no specific rule about left or right, but centering is the most common practice for a clean and balanced look.

However, depending on the specific document style or formatting guidelines you're using, the header might be aligned differently. For example:

* Formal documents: Headers may be left-aligned for a more formal look.

* Informal documents: Headers might be centered or right-aligned.

* Specific style guides: Check for instructions from your school, organization, or publisher.

Ultimately, the best placement is what looks best for the specific document and context.
