US Envelope Series



Belonging to the ISO A series, the A10 paper size is a compact and versatile choice for various applications. This smallest member of the ISO 216 standard measures a precise 26 x 37mm, making it an ideal fit for small-scale print projects.

Despite its diminutive dimensions, A10 holds its own in terms of utility. It's commonly used for stamps, business cards or tiny leaflets - applications where space efficiency is paramount. Its size also makes it perfect for labels on miniature products or as an information carrier on small items.

The ISO 216 standard that A10 adheres to ensures consistency across different paper sizes. This international standardization allows for seamless scaling between sizes without distortion or loss of content quality. For instance, two A11 sheets make up one A10 sheet and two A10s form an A9 - maintaining aspect ratio integrity.

In contrast to the ANSI series prevalent in North America, which uses letter-based designations and different proportions, the ISO series offers a more systematic approach based on consistent aspect ratios and size progression.

A fascinating fact about this paper size is that despite being small in stature, it plays a significant role in environmental sustainability efforts. The efficient use of space reduces waste during printing processes and contributes to resource conservation efforts globally.

While often overlooked due to its petite nature, the humble yet mighty A10 paper size serves as a testament to how effective design can maximize utility while minimizing waste – truly embodying efficiency at its finest.

Interesting facts about 10

1: The A Series Paper Sizes

The A series paper sizes, which are commonly used worldwide, were first introduced in Germany in the 1920s. The most well-known size is A4 (210mm x 297mm), which is the standard size for documents and letters in many countries.

2: B Series Paper Sizes

The B series paper sizes, also widely used globally, were developed as an alternative to the A series. Interestingly, each B size is exactly one half of the corresponding A size. For example, B5 (176mm x 250mm) is half the size of A5 (148mm x 210mm).

3: C Series Paper Sizes

The C series paper sizes are primarily used for envelopes and folders. These sizes have a different aspect ratio compared to both the A and B series. The most common C size is C4 (229mm x 324mm), which fits an unfolded A4 sheet perfectly.

4: US Letter Size

In the United States and Canada, the standard letter-size paper measures 8.5 inches by 11 inches (215.9mm x 279.4mm). This differs from the international standard of A4.

5: Ancient Chinese Paper

Paper was invented in ancient China around the year AD105 by a court official named Cai Lun during Emperor Han's reign. It was initially made from mulberry bark fibers mixed with water and then pressed into sheets.

6: Papyrus Sheets

Papyrus sheets were one of the earliest forms of paper used by ancient Egyptians around BC3000. They were made by slicing the pith of the papyrus plant into thin strips and then arranging them in two layers, crossing each other at right angles.

7: Rice Paper

Rice paper, also known as Xuan paper, is a type of paper made from rice straw or bark. It has been used for centuries in East Asia for calligraphy and painting due to its smooth texture and ability to absorb ink without bleeding.

8: Waterproof Paper

Waterproof paper is a special type of paper that can resist water damage. It is often used for outdoor applications such as maps, field notebooks, and even underwater notepads for scuba divers.

9: Origami Paper

Origami paper, traditionally called "kami," is a lightweight and colorful type of paper specifically designed for origami folding. It typically has a square shape and comes in various sizes ranging from small (7.5cm x 7.5cm) to large (30cm x 30cm).

10: Currency Paper

Currency notes are printed on a special type of durable paper called rag paper or banknote paper. This material consists of cotton fibers mixed with linen or other textile fibers to increase strength and prevent tearing.
