Business envelope size - Everything you need to know.

Business envelopes are an essential tool for any company that deals with mail. They come in various sizes, shapes, and colors, making them versatile and adaptable to any situation.

However, choosing the right envelope size for your needs can be confusing, especially if you're new to the business world. This guide will help you understand the standard envelope sizes, their ideal uses, and tips for selecting the right one for your business.

 

What is the size of a business envelope?

An envelope size refers to the dimensions of an envelope, typically given in inches. Sizes range from smaller envelopes like 3 ⅝ inches by 6 ½ inches, ideal for personal checks, to larger sizes like 12 inches by 15 ½ inches for bulky documents.

The size is determined by its length, width, and sometimes its depth, which dictates what the envelope can accommodate.
