How Big Is A 5×7 Photo

“How big is a 5×7 photo?” is commonly asked. A 5×7 photo refers to the dimensions of the photograph. Understanding photo dimensions is essential for photography, printing, and displaying images. If you have questions about 5×7 prints, you are in the right place. 

A 5×7 photo is 5 inches wide and 7 inches tall. In metric units, this is approximately 12.7 cm by 17.8 cm. These measurements represent the physical size of the printed photograph. This photo dimension is versatile and widely used in black-and-white photography. 

However, people need clarification in deciding the best dimension for their photos. Print dimensions vary, and the costs of prints aren’t always uniform. Additionally, technical aspects such as file formats, resolution, color modes, and scanning dimensions can intensify the challenge of finding the optimal answer.

In this article, you will learn everything about a  5×7 photo. So, without further ado, let’s start. 

How Big Is A 5×7 Photo In Pixels?

Photo Print Size

How big is a 5×7 photo in pixels? The size of a 5×7 image in pixels depends on the resolution at which the photo is displayed. Resolution is defined as the number of pixels per unit of length. It is often measured in pixels per inch (PPI) or per centimeter (PPCM). You’ll need to know the resolution at which it’s being viewed. Thus, you can determine the pixel dimensions of a 5×7 photo. 

Let’s Consider A Few Common Scenarios

High-Quality Print Resolution (300 PPI)

Suppose the 5×7 photo is going to be for high-quality printing at 300 pixels per inch. You can calculate the pixel dimensions as follows:

Width in pixels = 5 inches * 300 PPI = 1500 pixels and

Height in pixels = 7 inches * 300 PPI = 2100 pixels

So, a 5×7 photo at 300 PPI would have pixel dimensions of 1500 pixels by 2100 pixels.

Standard Print Resolution (150 PPI)

For traditional quality printing at 150 pixels per inch, the pixel dimensions would be:

Width in pixels = 5 inches * 150 PPI = 750 pixels and 

Height in pixels = 7 inches * 150 PPI = 1050 pixels

Therefore, a 5×7 photo at 150 PPI would have pixel dimensions of 750 pixels by 1050 pixels.

Screen Display (72 PPI)

A standard screen resolution computer monitor is 72 pixels per inch. The pixel dimensions would be:

Width in pixels = 5 inches * 72 PPI = 360 pixels 

Height in pixels = 7 inches * 72 PPI = 504 pixels

In this case, a 5×7 photo for screen display would have pixel dimensions of 360 pixels by 504 pixels. Remember that the higher the resolution, the more detail and clarity the image will have. But it might also result in larger file sizes. It’s essential to consider the intended use and the appropriate resolution. 

How Big Is A 5×7 Photo In Centimeters?

A 5×7 photo is approximately 12.7 cm wide and 17.8 cm tall. These dimensions are from the measurements in inches. Here, 1 inch is approximately equal to 2.54 centimeters. Thus, the conversion for a 5×7 photo is

Width in centimeters = 5 inches * 2.54 cm/inch = 12.7 cm 

Height in centimeters = 7 inches * 2.54 cm/inch = 17.8 cm

A 5×7 photo is roughly 12.7 cm by 17.8 cm in size.

How Big Is A 5×7 Photo In Millimeters?

A 5×7 photo is approximately 127 mm wide and 178 mm tall. This conversion is on the fact that 1 inch equals 25.4 millimeters. Thus, the dimensions of a 5×7 photo in millimeters are:

Width in millimeters = 5 inches * 25.4 mm/inch = 127 mm 

Height in millimeters = 7 inches * 25.4 mm/inch = 178 mm

Thus, a 5×7 photo measures approximately 127 mm by 178 mm.

Typical Uses Of A 5×7 Photo?

The common uses of a 5×7 photo pixel dimensions can vary. It depends on the context and intended purpose. Here are some typical scenarios:

Digital Displays

Digital Displays

A 5×7 photo is resizable to fit digital displays like computer monitors. For example, a standard screen resolution for web use is 1920×1080 pixels (16:9 aspect ratio). Yet a 5×7 photo is resizable to approximately 750×1050 pixels. 

Online Sharing


Resizing images to specific dimensions is common to ensure they get displayed correctly. For instance, Instagram photos are often displayed at around 1080×1350 pixels.

Desktop Backgrounds

Screen Resolution

Resize the photo to fit your screen resolution. Common desktop resolutions include 1920×1080 pixels or 2560×1440 pixels. They are 16:9 aspect ratios. Adjust the dimensions while maintaining the 5:7 aspect ratio.

Digital Photo Frames

Digital Photo Frames

Digital photo frames have specific screen resolutions. To display a 5×7 photo on a digital frame. So, you must resize the image to match the frame’s resolution.

Tips To Determine The Best Dimension For Your Photo?

Best Photo Dimension, How Big Is A 5×7 Photo

Determining the best dimensions for your photo depends on its intended use. You have to understand the purpose of the picture. Consider why you’re resizing the image. Is it for printing, online sharing, framing, or a specific project? Different goals must have different dimensions.

Now understand the aspect ratio. The aspect ratio is the proportional relationship between the width and height. Determine the required aspect ratio based on the intended use. If you’re printing the photo, research standard print sizes to find one that suits your needs. Standard print sizes like 4×6, 5×7, 8×10, etc., can help you choose appropriate dimensions.

You also need to consider the resolution. The resolution (pixels per inch) affects print quality. For high-quality prints, aim for 300 PPI. Calculate the pixel dimensions based on the desired print size and resolution.

4×6 vs. 5×7: Which One Is The Best Photo Dimension?

Photo Dimension, How Big Is A 5×7 Photo

The best photo dimension depends on your specific needs and preferences. Each size has its advantages. So, a specific one is better suited for a particular purpose. Here’s a comparison to help you decide:

4×6 Photo

  • Aspect Ratio: 4×6 has an aspect ratio of 3:2. It is the same as many digital cameras and 35mm film.

  • Snapshot Size: 4×6 photos are compact and convenient for carrying around in your wallet or sharing with friends.

5×7 Photo

  • Aspect Ratio: 5×7 has an aspect ratio of 3.5:2.5. It is slightly more rectangular than 4×6.
  • Framing: 5×7 photos can be more significant and more impactful when framed. They can stand out on a wall or shelf.
  • Portraits: The slightly larger size of 5×7 makes it better for portrait photography. It allows more room for details.
  • Gifts and Greetings: 5×7 can be used for creating personalized greeting cards, invitations, and skills.
  • Professional Display: Photographers often use 5×7 prints in portfolios to showcase their work.
  • Higher Resolution Options: The larger size allows for higher resolution. But the source image must be large enough.
