Why is 4×6 the Most Common Aspect Ratio?
You find the 4×6 aspect ratio everywhere in photography. That’s because of its 3:2 aspect ratio. It’s the standard size of photos in modern photography.
The 4×6 print size mirrors the aspect ratio of 35mm film cameras. And digital camera sensors have been made in the same way as the old film cameras.
So this 3:2 ratio is what most digital camera sensors use. That means most digital viewfinders are the same ratio.
It is also the most common size for 35mm prints. That’s why you find most photo albums in this size!
Common Issues With 4×6 Photos
There are a few problems to keep in mind with this standard picture size. It comes up when you want to print a 4×6 picture.
Cropping
Big printing services often prefer printing in the 4×6 size. That’s because it’s the best way to enlarge 35mm film pictures. But be aware that the photofinishing industry often trims off three millimeters on each side of the photo.
And their process for trimming the image isn’t exact. So ensure there are no critical elements along the edge of the image. Avoid faces and other important objects along the edge of your compositions.
Resolution
You do not want to print any lower than 480 x 640 pixels when printing a 4×6 photograph. Check the size of your photograph in Adobe Photoshop by opening up your photo and going to image > Image Size. Then change the parameters to pixels.
How to Resize a 4×6 Image
Smartphone sensors have a slightly bigger ratio than 3:2. The most common is 16:9. So I’ll show you how to ensure your photo is 4×6 without losing any image resolution.
First, you want to get your image up in Photoshop.
Go to the top and select Image > Image Size. Then change your parameters to adjust your image in inches.
Make sure you have the Resample box unchecked. Then enter the number six on the longest side of your photo.
Next, go back to the menu and click Image > Canvas Size. Again, change the parameters to inches.
The Anchor box will show you the point at which Photoshop will crop. You can change the anchor point according to the most crucial part of the image.
Now, you have a 4×6 photograph!
