Nominal sheet vs usable area
Borders, binding, title block, notes, schedules, legends, key plans, and spacing all reduce the region available to viewports.
Layout-quality check
A larger sheet is not automatically better. Select the smallest sheet and scale that keep geometry, annotations, references, and issue information complete and readable.
Sheet borders, binding margins, zones, title-block geometry, and folding requirements follow the project template and document-control standard.
