Tips for Choosing the Right Business Envelope Size

Choosing the right envelope size for your needs can be overwhelming, but it doesn't have to be. Here are some tips to help you select the right business envelope size:

 

Consider the size of your document: The size of your document should be the main factor in determining the envelope size you need. Measure your document and choose a slightly larger envelope to allow for easy insertion and removal.

 

Consider the weight of your document: If your document is heavy or bulky, consider using an expansion envelope to ensure it fits comfortably and doesn't get damaged during transit.

 

Consider the number of pages: If you're sending multiple pages, make sure the envelope size can accommodate them all without overcrowding the envelope.

 

Consider the purpose of the mail: Different types of mail may require different envelope sizes. For example, if you're sending a promotional brochure, a catalog envelope may be a better choice than a standard envelope.

 

Consider your branding: If you want to make a statement or showcase your brand, consider using a colored envelope that matches your brand colors.

 

Consider the mailing method: Some mailing methods, such as bulk, may require specific envelope sizes. Make sure to check with your mailing service provider before selecting an envelope size.
