When it comes to printing and sharing photos, understanding the dimensions and sizes of your images is crucial. One of the most common photo sizes is the 6×4, but have you ever wondered how big it is in centimeters? In this article, we will delve into the world of photo sizes, explore the history of the 6×4 format, and provide you with a comprehensive guide on how to convert inches to centimeters.
A Brief History of the 6×4 Photo Size
The 6×4 photo size has its roots in the early days of photography. In the 19th century, photographers used large-format cameras that produced glass plates with a standard size of 6.5 x 4.75 inches. This size became the norm for portrait photography, and it remained popular throughout the 20th century.
With the advent of digital photography, the 6×4 size continued to be a favorite among photographers and consumers alike. Today, it is one of the most widely used photo sizes for printing and sharing images.
Understanding Photo Sizes: Inches vs. Centimeters
When it comes to photo sizes, inches and centimeters are the two most commonly used units of measurement. While inches are widely used in the United States, centimeters are the standard unit of measurement in most other countries.
So, how big is a 6×4 photo in centimeters? To convert inches to centimeters, you need to multiply the inch measurement by 2.54. This is because 1 inch is equal to 2.54 centimeters.
Using this conversion factor, we can calculate the size of a 6×4 photo in centimeters:
6 inches x 2.54 cm/inch = 15.24 cm
4 inches x 2.54 cm/inch = 10.16 cm
Therefore, a 6×4 photo is approximately 15.24 cm x 10.16 cm in size.

Using a 6×4 photo in centimeters can be helpful when working with digital images or printing photographs in countries that use the metric system. It’s also useful to know the size of a 6×4 photo in centimeters when designing photo albums or frames.
What is the aspect ratio of a 6×4 photo?
The aspect ratio of a 6×4 photo is 3:2. This means that for every 3 units of width, the photo has 2 units of height. The 3:2 aspect ratio is a common format for digital cameras and is widely used in photography.
The 3:2 aspect ratio of a 6×4 photo is also known as a “3 by 2” or “3:2” format. It is a popular aspect ratio for printing photographs because it provides a good balance between width and height, making it suitable for a wide range of subjects.
Can I print a 6×4 photo in a different aspect ratio?
Yes, it is possible to print a 6×4 photo in a different aspect ratio. However, this may require cropping the image to fit the new aspect ratio. Cropping can affect the composition of the photo, so it’s essential to consider the impact of changing the aspect ratio before printing.
If you want to print a 6×4 photo in a different aspect ratio, you can use photo editing software to crop the image. Alternatively, you can use a photo printing service that offers custom aspect ratios. However, keep in mind that changing the aspect ratio may affect the overall quality of the print.
