What are the margin and paper size requirements for patent drawings?

MPEP 507 outlines specific requirements for margins and paper size in patent drawings:

Each sheet must include a top margin of at least 2.5 cm. (1 inch), a left size margin of at least 2.5 cm. (1 inch), a right size margin of at least 1.5 cm. (5/8 inch), and a bottom margin of at least 1.0 cm. (3/8 inch). The size of the sheets on which drawings are made must be either 21.0 cm. by 29.7 cm. (DIN size A4) or 21.6 cm. by 27.9 cm. (8-1/2 by 11 inches);

These requirements are based on 37 CFR 1.84(f) and (g). Adhering to these specifications ensures that the drawings can be properly scanned and reproduced in the patent publication process.
