How Big Is a 4×6 Photo – All You Need To Know!

5 Mins read

A 4×6 inch photo, or 4″x5 7/8 inches, is about 4×6 inches. It is the standard size because the print size mirrors most digital cameras viewfinder aspect ratios.

Digital cameras do not refer to smartphones. You may need to crop photos from your iPhone or Android phone for a 4×6 print.

This article will cover everything you need to know about 4×6 photos, including their sizes, uses, and whether it’s the best image format.

First, it is important to realize that there are many ways to measure a photo 4×6.

What is the size of a 4×6 Pixels photo?

This is dependent on the PPI (pixels per inch) of the digital software that you use.

The most popular PPI values are 125PPI or 300PPI.

A 4×6 photo on a 125PPI monitor is 500×750 pixels.

A 4×6 photo on a 300PPI monitor is 1200x 1800 pixels.

What is the size of a 4×6 photo in Centimeters

1.56 cm is equivalent to 2.56 cm.

A 4×6 photo is approximately 10x15cm in centimeters.

What is the size of a 4×6 photo in millimeters?

1 inch is equivalent to 25.4 millimeters.

A 4×6 photo is approximately 101.6×152.4mm in millimeters.

What aspect ratio does a photo 4×6 have?

An aspect ratio is the ratio of the width and height in a photograph. The ratio’s first number after the height is the width.

A 4×6 photo’s aspect ratio is 3:2 horizontally and 2:3 vertically.

What resolution is required for a 4×6 print?

Kodak recommends that a print measuring 4”x6” should have a resolution of 640 pixels minimum.

How to turn a digital photograph into a 4×6 printed photo

Modern smartphones like the iPhone and Android have a different ratio to a 4×6 image. You can convert an image to 4×6 by changing its aspect ratio.

Bunnypic is our online Photoshop editor that allows you to do this.

  1. Open your image in the Bunnypic Editor.
  2. Open your image and go to Image > Size.
  1. You can change the units from pixels to Inches. This will make the width and height 4 inches and 6 inches. This will give you a ratio 2:3. For horizontal images, the width should be 6 inches and the height 4 inches.

This is the difference between medium-format images and the new 4×6 image resize.

Because the original photo was too large, we had to scale down the 4×6 (2/3) photo. We reduce the size of the photo to preserve its quality.

How to prevent faces being cut out of your photos

Most printing companies might trim the edges of a 4×6 photo when you print it. This can be very frustrating, especially if you aren’t told before that your photo may get cropped.

Most photo printers will trim off 3mm (0.12 inches), of the edges of your photo. It doesn’t matter if you send a cropped photo, as the printer will still cut the image.

This will prevent you from losing important information such as faces, around the edges of your photos. You can use a safe space of three millimeters when you edit your image to determine how much of it will be cropped by the printer. This is a good rule of thumb.

Bunnypic is a good option.

  1. Open your image in the Bunnypic Editor.
  2. To display rulers for your document, go to View > Rules or hit CTRL+R
  3. Next, click and drag the rulers to create 0.12 inches of margin on all sides.

Use Photoshop

  1. Go to File >Open and open your image.
  2. Open your image and go to View>> New Guide Layout. Set your margins.
  3. After you click OK your document will include a safety margin at all four sides.

This will allow you to see how much of the document would be removed from the image. Any important elements placed outside of the margin will be cropped.

Uses for a 4×6 Photograph

The most popular image format is the 4×6. It has been so since 35mm film. A 4×6 image is ideal for photo albums, wallets and photo frames.

This is the perfect size for sending a postcard, as it was once known as “postcard-size”. It was the best size to send as a postcard, without needing an envelope.

These are just a few examples of what a 4×6 photograph would be perfect for:

  • Picture frames for shelves and tables, as well as desks
  • Photo albums
  • Picture collages
  • Photo reels
  • For abstract art, small art pieces are common.

This versatile format is not suitable for all photos, despite its many advantages. The 5×7 format is another popular photo format that is becoming more common.

4×6 VS5x7

We’ll be comparing the 2 most used formats in the photofinishing sector to determine which size is the best.

Personal preference is the most important factor. A 4×6 frame will likely be used for a 4×6 photograph, and vice versa.


Printing your photos is an expensive business. You might be able to print your family’s photo album on a smaller budget. You might be more price conscious if you are a professional photographer and need images in bulk.

A 4×6 image costs much less than a 5×6 format. The standard image format of 4×6 photos is the most cost-effective, so it’s the best option.

A 4×6 print costs $0.09, or 9 cents at Walmart. This compares to the $1.44, 1 dollar, and 44 cents that a 5×7 photo costs. The 5×7 image costs 16 times as much as a 4×6 print. This makes the 4×6 option more affordable.

Camera Aspect Ratio Vs Image Aspect Ratio

Digital cameras all support the 2/3 image format, which is commonly the default.

Direct printing can now be done with digital photos. A 5×7 image may need to be cropped with a photo editing program such as Bunnypic.

Picture frames

Many people get their photos printed so they can be hung in the home or incorporated into the decor. You need to choose the right size print for you if you’re one of these people.

It all comes down to what you need. A 4×6 picture frame will require a 4×6 photograph to ensure it fits perfectly. A 5×7 print is required for a 5×7 frame.

You must consider the entire size of your photo, including the borders, if you want to add a white border around it.

A border makes your photo look cleaner and more professional. You could end up with your photo being cropped incorrectly if the border is too small.


The last thing to consider is the detail of your actual photo.

The 5×7 format is better for images that are very detailed, such as city views. The reason is that the 4×6 image might not be as clear if viewed from far away. A 5×7 photo covers more area.

A 4×6 photo is fine for printing family photos or abstract art. You can print 5×7 prints of city views, landscapes, and seascapes.


A 4×6 photo measures 4 x 6 inches (10 x15cm/101.6×152.4mm) and has an aspect ratio of 2:1.

Industry standard size for photo prints is 4×6. It can be used with all digital cameras and is more versatile than a 5-x7 photo.

Prints of smaller art pieces, family photos and postcards can be made with 4×6 photos. If you have a highly detailed image you might want to look into
