Postage Without Additional-Ounce Stamps

Stamps 1.4: Android app of this page, Featured shareware product

The postage rate for mailing a regular first-class letter in the United States starting April 10, 2016 is $0.47 for the first ounce and $0.21 for additional ounces up to 3.5 ounces. After that, you must use the rate for large envelopes, called flats, which starts at $0.94 and also adds $0.21 for additional ounces. The package rates for one through three ounces went up on August 28, 2016.

Suppose that you only have 47-cent stamps. What should you do? You could affix one such stamp for each ounce. However, two first-ounce stamps covers three ounces for a letter. The first table below shows the costs for up to 13 ounces and the number of first-ounce stamps needed when you don't have additional-ounce stamps. (After 13 ounces, mail with stamps applied must be presented at a post-office counter.) The second table below shows the values when only first-ounce stamps are applied and how many ounces for letters and flats are covered by using only these stamps.

Following are the size requirements on letters and large envelopes (flats). If any of the limits on flats are exceeded, then package rates apply. If any of the limits on letters are exceeded without exceeding the corresponding limit for flats, then the rates for flats apply. The minimum requirements must be met for both letters and flats.

Dimension Minimum (in) Limit-Letters (in) Limit-Flats (in)
Length (side to side) 5 11 1/2 15
Height (top to bottom) 3 1/2 6 1/8 12

Reference 1 contains the following notice about letter requirements:

Letters that meet one or more of the nonmachinable characteristics below are subject to the nonmachinable surcharge.

This surcharge currently is $0.21.

Reference 2 contains the following notice about large-envelope requirements:

Stamps App

An Android app of this page is now available in the Google Play store and in the Amazon Appstore.

Here is what this app can do that this page doesn't do.

  1. The app is designed to fit on a smartphone screen. This web page doesn't display well on a smartphone.
  2. This app can show you how much extra you would be paying if you use only first-ounce stamps.
  3. This app can handle when a letter or large envelope does not meet requirements.
  4. This app allows you to adjust postage costs up to 50 cents more.

Featured Shareware Product

CopyFolder (Filtered Folder Copier) 1.7
CopyFolder 1.7 is a filtered folder copier that copies your files in their original formats. As a result, you can access your copied files without using this program. After using the preview feature to generate a list of files to copy and making any adjustments to this list, you can press the Copy button and then do something else while this program runs. Unless you tell it otherwise, CopyFolder will run unattended after initial validation until it copies all the files it can and presents a summary report.

CopyFolder requires Windows 98 or NT 4.0, or later. Copying file-security settings requires Windows XP or NT 4.0, or later, and administrator privileges. This shareware program does not contain any adware or spyware. (Trial period: 15 days-of-use or 30 copy-operations within 60 days. Initial fee: $9.99. Upgrade fee: $5. Fee with all upgrades included: $19.99. Released on 2-June-2016.)

Major new features: queues of setting sets (called profiles), allows changing drive letters, selection tests based on size and/or archive attribute, remaining-time estimate, better display of file and folder counts, Folder List display, option to adjust column widths to show entire content
