Final answer:
The standard paper size for official stationery is A4 globally and Letter size in the US and Canada. Formatting entails using 8 1/2 x 11" white paper, 1-inch margins, and a 12-point legible font. Proper netiquette is important for a professional online presence.
Step-by-step explanation:
The standard size of paper for all official stationary is typically A4 or Letter size. A4 is the standard size used globally, with dimensions of 210mm x 297mm (8.27 inches x 11.7 inches). In the United States and Canada, however, the standard size is Letter, which is 8 1/2 x 11 inches. In professional settings, business documents such as business letters, cover letters, and resumes should adhere to specific formatting requirements. These include using 8 1/2 x 11" white paper (standard printer paper), with 1-inch margins and a 12-point Times New Roman font or a similarly legible font.
For business correspondence, block formatting is normally used where all text is left-justified, single-spaced, with a double space between paragraphs. The choice of paper weight also matters, especially for documents such as wedding invitations. Commercial papers are often sold by weight, with 500 sheets constituting a ream, and the weight can vary depending on the quality of the paper. For everyday business needs, a lighter paper, around 60 lb., is standard, whereas special occasion papers might be heavier, such as 100 lb. stock. It's important to use proper netiquette and make a positive impression online when engaging in business communications.
