Frequently Asked Questions (FAQs) | Letter Jacket Envelopes


How do you correctly measure a window or envelope?

Always place the envelope in front of you with the flap at the top. Measure the height of the window first, then the width. The first measurement is always considered the height and the second measurement the width. This indicates whether the window is vertical or horizontal to the flap. The position of the window should be measured from the left of the envelope to the left of the window and then from the bottom of the envelope to the bottom of the window.

How do I apply my coupon code?

How do I edit my password?

What is bleed?

What is a standard window?

A standard window must meet 4 measurement specs. The size of the window must be 1 1/8″ x 4 1/2″ and positioned 7/8″ left and 1/2″ from the bottom. If any one of these measurements is different, the window is considered to be special or custom.

What types of artwork do you accept?

When uploading art to the Design Online page, the preferred file type is EPS, as this file type is vector art designed to scale properly. We can also accept Photoshop (.PSD) files, PDF, JPEG and PNG files.

  • Open the file in Adobe Illustrator
  • In the top menu bar, select File > Save As…
  • Under Format, select “Illustrator EPS (EPS)”

You can now use this EPS in the Designer when designing your envelope online.

When uploading a Completed Design, the preferred file type is Adobe Illustrator (.AI), but we can also accept Photoshop (.PSD) files, PDF, EPS, JPEG and PNG files. If you specify two or more colors for printing, you should provide vector art (either Illustrator or EPS) designed to scale properly.
