International Envelope Series
R1
The R1 paper size, a member of the ISO 216 standard, is a unique and versatile format. It measures 648 x 917 mm or 25.5 x 36.1 inches, making it an ideal choice for various applications.
As part of the ISO's "R" series, R1 stands out due to its distinct dimensions that are not found in the more commonly used "A" or "B" series. This makes it particularly useful for specific projects where traditional sizes may not suffice.

Interestingly, the ISO's "R" series was designed with a specific purpose in mind: to accommodate formats that don't fit within the constraints of other series. The R1 size embodies this flexibility perfectly.
Moreover, while ANSI standards are prevalent in North America, ISO standards like R1 are recognized and utilized globally. This international recognition enhances its versatility and applicability across different regions and industries.
Whether you're working on a design project or preparing large-scale prints, consider leveraging the unique attributes of R1 paper size. Its distinctive dimensions coupled with global recognition make it an excellent choice for diverse needs.

Interesting facts about R1
1: R1 paper is part of the ISO 216 standard
R1 paper is a size that belongs to the ISO 216 standard, which is an international system for paper sizes. This standard was first introduced in 1975 and has been widely adopted around the world.
2: R1 paper measures approximately 707 mm x 1000 mm
The dimensions of R1 paper are approximately 707 mm x 1000 mm (27.8 in x 39.4 in). It has a portrait orientation, meaning it is taller than it is wide.
3: R1 paper is commonly used for posters and large format prints
R1 paper's larger size makes it ideal for printing posters, banners, and other large format prints. Its dimensions provide ample space for displaying detailed graphics or text.
4: R1 paper originated from the German DIN standard
The ISO A series of papers, including R1, was derived from the German DIN (Deutsches Institut für Normung) standard introduced in the early twentieth century. The DIN standard aimed to establish a consistent set of paper sizes across Germany.
5: The aspect ratio of R1 paper is approximately √2
The aspect ratio of R1 paper (the ratio between its longer side and shorter side) is approximately √2 (square root of two). This aspect ratio allows easy scaling between different ISO sizes without altering proportions.
6: The weight of R1 paper can vary depending on its thickness
Rather than having a specific weight assigned to it, the weight of R1 paper depends on its thickness or grammage. Common weights for R1 paper range from 80 gsm (grams per square meter) to 300 gsm, with heavier weights being more suitable for durable prints.
7: R1 paper is not commonly found in everyday office use
While R1 paper is widely used in the printing industry, it is not commonly found in everyday office settings. Its larger size makes it less practical for standard office documents and printing needs.
8: R1 paper can be cut down to smaller sizes
If needed, R1 paper can be easily cut down to smaller sizes using a trimmer or cutter. This flexibility allows for customization and adaptation of the paper to specific project requirements.
9: The ISO A series includes larger sizes than R1
The ISO A series of papers extends beyond the size of R1, with larger formats such as A0, A1, and A2 available. These larger sizes are often used for architectural drawings or other specialized applications.
10: The ISO B series complements the ISO A series
In addition to the ISO A series, there is also an ISO B series that complements it. The B series has different dimensions but maintains the same aspect ratio as its corresponding A size. This allows for easy scaling between both series when necessary.
