What is the size of a one-inch photo?
In today's era of social media, taking photos has become an indispensable part of our lives. Whether it's a gathering with friends, a trip, or a memorable occasion, we always like to capture those beautiful moments. When we need to print a photo or apply for various documents, the photo size becomes an important issue. Among them, the size of a one-inch photo is the most common and universal. So, what exactly is the size of a one-inch photo?
According to the international standard ISO/IEC 19794-5, the size of a one-inch photo is 2.5 cm (width) × 3.5 cm (height). This specification is widely used for passport photos, identity cards, driving licenses, and other ID photos. The aspect ratio of a one-inch photo is 5:7, matching the standard photo frame size. Therefore, if you need to print a one-inch photo, you can crop it according to this size or adjust it using online photo editing tools.
When taking a one-inch photo, it is important to pay attention to the following points: firstly, ensure that the portrait is clear and facial features are complete; secondly, keep the background simple and monochromatic, with pure white being the commonly used background color. Also, pay attention to even distribution of light and appropriate brightness to ensure stable photo quality and recognizability.
By understanding the size of a one-inch photo, we can easily handle the requirements of various ID photos. This makes applying for a passport, ID card, or other documents more convenient and efficient. Whether using online printing services or self-cropping, as long as we process the photos according to the correct size, we can obtain one-inch photos that meet the requirements.
