How to Measure

Flat Envelopes

Measure "width" x "length".
Width: Is always the shorter measurement.
Length: Is always the longer measurement.

Flat Envelopes

Flat Envelopes

Catalog: 9" x 12"
Width = 9"   Length = 12"

Flat Envelopes

#10 Regular: 4 1/8" x 9 1/2"
Width = 4 1/8"   Length = 9 1/2"

 Expansion Envelopes

Expansion Envelopes

Expansion Envelope: 9 1/2" x 13" x 2"
Width = 9 1/2"   Length = 13"
Thickness = 2"

Measure width and length the same as shown on the Flat envelopes, using the shorter measurement as the width and the longer measurement as the length.

When measuring the Gusset Edge, measure the distance from the fold of the flap to the first score line at the bottom.

If the flat size is also requested, measure the gusset edge from the fold of the flap to the actual bottom edge of the unexpanded envelope.

An expansion envelope will have a 3rd measurement which is the thickness that the envelope expands to.

Gusset Edge: The area on the sides of an envelope that allow the envelope to expand.

Window Size and Placement

Most any type of envelope can have a window cut into it but there are many standard window sizes available.   An additional charge is normal for custom windows to be added.

Window: A cut out that allows a portion of the content of the envelope to be seen.

Shown below is how to measure the window size and placement of the window on the envelope.

How to Measure Window Size:

Measure: Height x Width
First measurement is the height.
Second measurement is the width.

When measuring, have flap at top.


Window Size and Placement

Standard Window Size: 1 1/8" x 4 1/2"
Height = 1 1/8"   Width = 4 1/2"
From Left = 7/8"
From Bottom = 1/2"

Placement of Window:

Measure from left edge of envelope to left edge of the window.
Measure up from bottom edge of envelope to bottom edge of window.
