 ```I don't know where or how to find this out... Hence why I'm coming here... I have a software that I'm building to print out a document. These documents may be mailed to recipients, in fact this is quite common, so I have the idea of automatically labeling a sheet of paper with the addresses so that a business envelope may be used. To my disappointment, I found out that there are many different sizes of windo envelopes available. I'd like to find the most common margin/dimesion set(s). Is there a site that lists such statistics? How far from the top/left (from address) is the first window? How tall is it? (Width is not a requirement) How far from the top/left (to address) is the window? My only other options to use this feature are to sell envlopes out of my office that my application is designed to fit or to rquire the user to measure their envlope.```

 ```Hi tony8312, If you plan on a window being 5/8" from the bottom, and 7/8" from the left and the size 1-1/8" x 4-1/2", you should catch most addresses. Remember that the address itself must have at least a 1/8" space on all sides between it and the edge of the window. California State University "Normal window placement is ½" from the bottom and 7/8" from the left. Window size is 1 1/8" x 4 1/2"." http://www.csus.edu/mail/us_postal.doc Single-Window Envelopes Theoretically, nearly each envelope type and size may have a window, this generally depends on the manufacturer. The most common (and recommended by USPS) window size is 1 1/8 x 4 1/2, and the position 7/8 in from left and 1/2 (often 5/8) in from bottom, but there are lots of variations. [see graphic] Addressing and Printing Guidelines The correct formatting and address position on an envelope is required to facilitate mail processing by optical character recognition equipment, used by many postal services for sorting mail. Machine-readable mail can be sorted automatically, rather than by a human, which results in faster and more accurate delivery. Here is the picture that illustrates the correct address position: [see graphic] http://www.belightsoft.com/products/companion/paper/envelopes.php USPS 600 Basic Standards for All Mailing Services 601 Mailability 6.3 Window Envelope For all letter-size and flat-size mail in window envelopes, every character in the delivery address, including any postal barcode, marking, or endorsement, must be completely visible through the window throughout the full range of movement of the insert bearing the delivery address. Any window envelope used for letter-size or flat-size mail claimed at automation rates or for letter-size mail claimed at Enhanced Carrier Route high density or saturation rates must also meet the barcoding standards for letters and flats in 708.4.0. Any window envelope used for letter-size or flat-size mail claimed at any other rate must meet the following additional standards: a. The address and any barcode visible through the window must be printed on white paper or paper of a very light color. b. A clear space of at least 1/8 inch is required between the address block, which includes any optional endorsement line and any barcode, and the top, bottom, and left and right edges of the address window, and must remain when the insert is moved to its full limits in each direction within the envelope to ensure efficient processing and delivery. For nonautomation rate mail, the bottom edge of the address window must not extend more than 1/8 inch into the barcode clear zone as defined in 202.5.1. Any letter-size envelope containing a window that intrudes into the barcode clear zone is not eligible for MLOCR or RVE FASTforward processing options for the Move Update standard in 233.3.5. http://pe.usps.com/text/DMM300/601.htm 202 Elements on the Face of a Mailpiece 2.1 Address Placement Causing Mail to be Nonmailable and Nonmachinable The location of the delivery address on a letter-size mailpiece determines which dimensions are the length and height of the piece. The length is the dimension parallel to the address as read; the height is the dimension perpendicular to the length. Consequently, the placement of the address may render a piece nonmailable or nonmachinable. On a letter-size piece, the recommended address placement is within the optical character reader (OCR) read area, which is a space on the address side of the mailpiece defined by these boundaries (see Exhibit 2.1, OCR Read Area): a. Left: 1/2 inch from the left edge of the piece. b. Right: 1/2 inch from the right edge of the piece. c. Top: 2-3/4 inches from the bottom edge of the piece. d. Bottom: 5/8 inch from the bottom edge of the piece. {see graphic] Exhibit 2.1 OCR Read Area d. If a window envelope is used, the clearance between the leftmost and rightmost bars and any printing or window edge must be at least 1/8 inch, and the clearance between the barcode and the top and bottom window edges must be at least 1/25 inch. These clearances must be maintained during the insert's range of movement in the envelope. Address block windows on heavy letter mail (as defined in 5.2, General Barcode Placement for Letters) must be covered; such windows may be covered on other mail. Covers for address block windows are subject to 5.11. http://pe.usps.com/text/DMM300/202.htm#wp1047221 I was glad to find this for you.

 ```Dear tony8312, Thanks so much for your nice note, rating, and tip! I found the research quite interesting and even dug into my recycling box to find envelopes with windows so I could measure and take my own little survey. It's something one doesn't really think about unless asked. I was amazed to see such a variety of windows in just my pile of envelopes, but when I actually measured them, most came pretty close to the USPS standards. Good luck with your project! Sincerely, hummer```
 ```I hope you get emails regarding when a comment is posted hummer-ga. I just wanted to let you know that your help has withstood the test of time for a few different envelope sizes. I still very much appreciate the depth of this answer.```
 ```Dear tony8312, It's nice to hear from you! I have thought of you too since we last wrote, particularly when I receive an envelope with a weird window - I always feel compelled to get out my ruler (see what you've done to my poor brain!). Yes, it would be nice if the email notification feature would work but alas, GA hasn't been able to fix it yet. Hope you get this! Take care, H```
