RAW Series
SRA4
Belonging to the ISO 216 standard, SRA4 paper size is a unique and versatile choice for various printing needs. This format measures 225mm by 320mm, providing ample space for creative designs and detailed content. It's an ideal choice for those seeking a balance between the compact A4 size and the larger A3 format.
As part of the Supplementary Raw Format (SRA) series, SRA4 offers additional margins for professional printers. These extra margins are crucial in commercial printing processes where bleed is required. The bleed ensures that your design or text extends all the way to the edge of the paper after trimming, resulting in a polished and professional finish.

The SRA series, including SRA4, is not as widely recognized as its A-series counterparts. However, it holds significant value in specialized fields such as graphic design and commercial printing due to its unique dimensions that accommodate bleeds.
Despite being less common than other formats like A4 or Letter (ANSI Series), SRA4 has carved out its niche in specific industries. Its distinctive size makes it an excellent option for creating booklets or brochures with a more substantial feel than traditional formats.
While SRA4 may not be your everyday paper size, it's an invaluable asset when precision matters most - from professional print jobs to high-quality marketing materials.
