Pages vs. Sheets

Getting Started

When sending documents through LetterStream, it's important to understand the distinction between "pages" and "sheets." This article explains the difference and how it impacts your mailings, especially when using duplex printing.

What Are Pages?

Pages refer to the number of individual pages within your digital document. For example:

  • A 10-page PDF = 10 pages, regardless of how it's printed.

This count is based on the content and layout of the document itself.


What Are Sheets?

Sheets refer to the actual number of physical paper sheets used when printing the document.

  • Example: A 10-page PDF document printed simplex (single-sided) = 10 sheets
  • Example: The same document printed duplex (double-sided) = 5 sheets

This distinction matters for:

  • Pricing
  • Envelope selection
  • Postage

How Duplex Printing Affects Sheet Count

Duplex printing reduces the number of sheets used by printing on both sides of the paper. This is especially useful for keeping mailings compact and potentially lowering costs.

  • Example: A 30-page document, printed simplex would require 30 sheets and must be sent in a flat envelope
  • Example: A 30-page document, printed duplex would require 15 sheets and can be sent in a standard #10 envelope
