Where are preprinted title blocks most commonly placed on a sheet?

Preprinted title blocks are commonly placed at the bottom of a sheet. This placement provides a consistent location for important information such as the project title, designer, date, and revision history, ensuring that this information is easily accessible and does not obstruct the primary content of the drawing. Having the title block at the bottom keeps the upper portion of the sheet clear for the main design or graphical content, promoting clarity and organization in the presentation of drawings or plans. This practice is widely recognized in architectural and engineering documentation standards.

While options such as placing the title block in the center, on the left-hand side, or on the right-hand side could be considered, they do not align with the conventional approach used in the industry, which favors the bottom placement for the title block for the sake of clarity and ease of reading.
