what a manila envelope is, they’re usually thinking of that familiar yellow‑brown envelope used for mailing or storing important papers. A manila envelope is more than just stationery — it’s a durable, practical, and professional way to protect documents. At RSF Packaging, we understand the importance of secure packaging, and Manila Envelopes remain one of the most reliable tools for everyday mailing and filing.

What is a Manila Envelope?

A manila envelope is a large, sturdy envelope made from brown kraft paper. The name comes from Manila hemp, a fiber from the Philippines used in papermaking since the 1830s. That’s why people often ask, why is it called a manila envelope? The answer lies in its origin the fibers gave the paper strength and durability, making it perfect for envelopes.

Today, these envelopes are widely used in offices, schools, and homes. They’re ideal for mailing contracts, storing insurance policies, or organizing paperwork.

Sizes and Dimensions

One of the most common questions is about manila envelope sizes. The standard manila envelope size is 9" x 12", perfect for letter‑sized documents without folding. Other popular sizes include:

  • 10" x 13" – slightly larger, often used for thicker stacks of paper.
  • Legal size manila envelopes – designed for legal documents, usually 9.5" x 15".
  • Catalog envelopes – larger dimensions for photos, booklets, or bulky items.

Manilla envelope size or manilla envelope dimensions, and the answer depends on the type of document you want to store. RSF Packaging offers custom manila envelopes so you can choose the exact size that fits your needs.

Thick Manila Envelopes

Sometimes, a thick manila envelope is necessary for mailing multiple pages or heavier items. These envelopes are made with stronger paper weight (28 lb or more) and reinforced seams. They’re perfect for mailing catalogs, reports, or photographs.

Mailing and Addressing

A common question is: can you mail manila envelopes? The answer is yes. You can send them through the postal service just like regular envelopes.
