When people think of a manila envelope, they picture the familiar yellow-brown stationery used for mailing or storing documents. But what is a manila envelope? It’s more than just paper — it’s a durable, professional tool designed to protect contracts, reports, and important files. At RSF Packaging, we provide standard manila envelope sizes, custom manila envelopes, and eco-friendly options to fit every need.

What is a Manila Envelope?

A manila envelope is a large, sturdy envelope made from 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 fibers gave the paper strength and durability, making it perfect for envelopes. Today, these envelopes are widely used in offices, schools, and homes.

Manila Envelope Sizes and Dimensions

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

10" × 13" manila envelopes sizes – slightly larger, often used for thicker stacks of paper.
Legal size manila envelopes – usually 9.5" × 15", designed for legal documents.
Catalog envelopes – larger dimensions for photos, booklets, or bulky items.
Small manila envelope – compact for everyday use.

Whether you need thick manila envelopes for heavy mailing or custom printed manila envelopes, RSF Packaging offers durable solutions tailored to your project.
