Manila Envelopes: Sizes, Clasps & Custom Printing Guide

Introduction

The manila envelope is the brown, lightweight document carrier that offices and institutions have used for a century — the envelope for filing, interoffice mail, contracts, and anything that shouldn’t be folded. Its tan-brown color and smooth finish are instantly recognizable, and the name “manila” refers to both the material and the color.

Manila envelopes are a large, underserved category: the search term “manila envelope” carries roughly 14,800 monthly searches, yet many businesses never stop to think about the choices — clasp versus open-end, #10 versus 9×12, light versus heavy stock, or when to print on them.

This guide covers manila envelopes end to end: what they are, how they differ from kraft, the standard sizes, clasp and closure options, paper weights, common uses, and custom printing. For the material-manufacturing angle, see our kraft envelope manufacturing standards piece.
