± 3 mm (0.12 in) for lengths and breadths above 600 mm (23.6 in).± 2 mm (0.08 in) for lengths and breadths between 150 mm and 600 mm (5.9 in and 23.6 in).± 1.5 mm (0.06 in) for lengths and breadths below 150 mm (5.9 in).

#ENVELOPE SIZE ISO#

In ISO 216, avoidance particularized for the C envelope sizes are the same for A & B order paper sizes and are in this manner: This is because the output is an error-prone process and mechanical and human errors can always be created. ISO has also stated the maximum errors or tolerances that each size can have during production. For this reason, the sizes are always rounded off to the nearest millimeter.

As the aspect ratio is an irrational number the dimensions generally exceed the standard conventions and precision is hard to achieve.

This makes the size C(n) an almost exact fit envelope for holding the unfolded sheet of paper of size A(n). length of C(n) size = √ (length of A(n) size) × √ (length of B(n) size) and same for the breadth.

Any Size C(n) is defined as the geometric mean of the A(n) and B(n) Sizes.

Thus, an A4 Size Paper when folded parallel to its shorter sides easily fits in a C5 Envelope and when wrapped again along the shorter sides will fit comfortably in a C6 Envelope because of the maintaining of aspect ratio √2:1.

Every size should have an aspect ratio of √2:1 in the C Series Envelope Sizes (to help with easy resizing).

The ISO 216 Standard for C Series Envelope Sizes is formed of a few other rules. These properties help in easy resizing of all the ISO 216 Paper Sizes.

When we attach such a paper with another article of the same dimensions along one of the larger sides, the newly formed more prominent paper also has an aspect ratio of √2:1.

When we fold such a paper or cut precisely into two halves parallel to the two shorter sides, then the two newly created documents also have an aspect ratio of √2:1.

The ISO 216 was formed based on the old German DIN 476 Standard which further references a letter by a scientist describing the specialties of the √2:1 aspect ratio.

This helps to make these papers easily resizable. All paper and envelope sizes included in the ISO 216 follow a basic rule that they should have an aspect ratio of √2:1.

The dimensions of Paper Sizes in C Series Envelope Sizes have very precisely defined in the ISO 216.

Also, different ranges of US & North American Envelope Sizes, as not contained under ISO 216, contain the three main types of wrapper profitable, notice, and name. The article determines you are accompanying the capacity of each wrapper when distinguished to a sheet of A4 paper. US & North American Envelope Sizes are not covered by ISO 216, that’w why we’ve mentioned them on this page. For this, we created the Standard C Series Envelope Sizes. So, when paper sizes has standardized, it was important that Envelope Sizes too should have standardized. Envelopes are so helpful that we use them everywhere and for all purpose of sending documents. Envelopes have been used for centuries to enclose letters and other documents, and they have proved to be useful for the ease of transportation, maintaining of confidentiality, and prevention from threats to security.
