What is the standard picture size?
Before we take a look at the various photo sizes, you might be wondering what the most common photo size is. The standard photo size is 4 x 6 inches, often known as the 4R size.
One reason this photo print size is so popular is that it fits into many photo albums and frames. It’s easy to display and works with the standard photo paper size. So, it’s a safe printing photo size to choose from.
But it’s also just the right size. It’s large enough to see all the details clearly, but it doesn’t take up too much space.
On top of this, it’s become the regular photograph size as it has a 3:2 aspect ratio. Most cameras also use this ratio, including smartphones and digital cameras. As a result, your shots will look clean and natural.
If you stretch an image to a different aspect ratio, it can look distorted and create a skewed effect. And that’s why the 4R photo is the most common and has become accepted as the standard photo size.
What is the aspect ratio?
Understanding the aspect ratio of your photos will help you to get the right image sizes. It may sound a little complicated, but it’s actually very simple.
The aspect ratio is the width of the image compared to the height. For example, an image with a 3:2 ratio could measure 2 x 3 inches or 4 x 6 inches.
Here are some other common aspect ratios for photos:
- 1:1 – this creates a square image
- 4:3 – the size of many computer screens and some digital cameras
- 16:9 – a wider yet common size that’s used for certain social media posts and some computer monitors
Is there a standard wallet photo size?
You may have heard of a standard wallet photo, even though they’re less common than before.
The regular size for wallet photos is 2.5 x 3.5 inches or 6.35 x 8.89 cm. It fits neatly into most wallets and purses, making it a reliable size.
The Two Main Types of Standard Photo Sizes: R & A Series
There are two common ways to measure photo sizes. It can be helpful to understand each one, so you know what people are referring to if they use the other system.
So, let’s take a quick look at the R & A Series of photo sizes.
R Series Explanation & Photo Size Chart
The R Series is the most common method used for photo sizes across the world. Photo printing labs use these sizes, and it’s pretty straightforward when you know how it works.
The sizes in the R Series have a number before the letter R, e.g. 2R, 3R, 4R. The number refers to the length in inches along the shorter side.
This size chart shows the different photo sizes of the R Series and their dimensions:
|Print Name||Size in Inches||Size in CMs|
|2R||2.5 x 2.3||6.32 x 8.89|
|3R||3.5 x 5||8.89 x 12.7|
|4R||4 x 6||10.2 x 15.2|
|5R||5 x 7||12.7 x 17.8|
|6R||6 x 8||15.2 x 20.3|
|8R||8 x 10||20.3 x 25.4|
|S8R||8 x 12||20.3 x 30.5|
|10R||10 x 12||25.4 x 30.5|
As mentioned before, a standard photo is 4R. If you want a poster-sized print, you could go for 10R or 8R.
For slightly larger prints, 5R and 6R work well. 2R or 3R make for nice business cards or mini photos.
A Series Explanation & Photo Size Chart
The International Standard Organization (ISO) created this series of photo sizes. You may be familiar with these sizes as they’re also used for regular paper. So, you might have heard these terms at school.
For example, you have the regular A4 sheet, the smaller A5 size, and the large A3.
It’s a little confusing because as the numbers in the names get smaller, the photo gets bigger. So, the largest in the A-Series is the A1, measuring a whopping 23.39 x 33.11 inches.
The series continues all the way down to A10, which is just 1 x 1.5 inches.
Here’s a complete photo size chart for your reference:
|Print Size||Size in Inches||Size in CMs|
|A1||23.4 x 33.1||59.4 x 84.1|
|A2||16.5 x 23.4||42 x 59.4|
|A3||11.7 x 16.5||29.7 x 42|
|A4||8.3 x 11.7||21 x 29.7|
|A5||5.8 x 8.3||14.8 x 21|
|A6||4.1 x 5.8||10.5 x 14.8|
|A7||2.9 x 4.1||7.4 x 10.5|
|A8||2 x 2.9||5.2 x 7.4|
|A9||1.5 x 2||3.7 x 5.2|
|A10||1 x 1.5||2.6 x 3.7|
With these charts, you can select the size depending on your needs.
