What’s the Largest print can make from an iPhone photo – updated 2023
>้ฑ่ฎไธญๆ็ๆฌ
Apple release new iPhone models every year, we’ve found the image quality taken by iPhone camera keep improving. As a Fine Art Printer, we keep hearing the same question: “What’s the largest print I could make from an iPhone photo?”
In fact, many people are using iPhone as their day to day camera now. Currently their latest model can take a raw image up to 48MP. In here we will focus on the default 12MP size we can get from any iPhone regardless which model you are using. The way it works can be applicable to other android phone and digital camera.
Old photos before upgrade to new iPhone
“I have many photos in my phone taken by different iPhones in the past, do I need to know the photo taken by which iPhone?”
No, we do not need to worry about which iPhone was used when the photo was taken. There is a “free” tool to help. If you are serious about photography, most likely you already have Photoshop Express Photo Editor installed in your phone. If not, just go to App Store to grab it.
Allow access to All Photos
Once the app is downloaded and installed in your iPhone, you can open Photoshop Express, don’t forget to choose “Allow access to All Photos” to easily access and edit your phone images.
After an image is opened, select the 3 “white dots” to open a dialog box. This will give you further options. Then we can select “Show Info” to see more information about the photo.
Check the number of pixels of your photo (W x H)
After “Show Info” is selected, additional information of the photo will be show on the bottom. In this example, we can see the photo file size is 7.02MP. However, the most important information is the dimension of the photo, here we know it is 2247 x 3278 pixels.
Update on latest iPhone 14, the rear camera takes much larger image as large as 48MP raw format, but we will use the default 12MP (4032 x 3024 pixels) here as an example.
What is the largest print we can make from the photo without loosing in picture quality?
In most of the photo applications, we determine the print quality by “Pixel Per Inch” or “ppi”. In general we do not recommend the resolution go lower than 240 ppi, which will give you a very decent Fine Art Print quality. With this resolution, it is within an arm length print appreciation distance.
Update – Using the default 12MP photo (4032 x 3024 pixels)
As we are using the default 12MP resoulution, the photo short side and long side are as much as 3024 pixels and 4032 pixels respectively. We can go ahead to divide 3024 and 4032 by 240 ppi, and obtain the print dimension in inches.ย
Now we know we can create a 12.6 x 16.8″ (~32 x 42.5cm), which is A3 paper size print at 240 ppi Fine Art Print quality.
The size seems smaller than I wanted, can it be larger?
The answer is “Yes”, you can print larger than this size, as long as you change your viewing distance for appreciation. This is similar concept of buying a TV in your living room. The longer distance between your sofa and TV, the larger TV you can choose. The Photo Prints are similar, the longer distance for appreciation you allow, the larger print you can create.
The recommended ppi verse viewing distance
The ideal resolution (ppi) of your print depends mostly on how far away the print is from the viewer. Here’s a chart to show you what resolution to aim for when creating your print.
| Viewing Distance | Pixel Per Inch |
|---|---|
| 0.6m /ย 2ft | 240 ppi |
| 1m /ย 3.3ft | 180 ppi |
| 1.5mย / 5ft | 120 ppi |
| 2mย / 6.5ft | 80 ppi |
| 3m /ย 10ft | 60 ppi |
| 5m /ย 16ft | 30 ppi |
| 10m / 33ft | 15 ppi |
| 15mย /ย 50ft | 12 ppi |
| 50mย /ย 160ft | 4 ppi |
| 60mย /ย 200ft | 3 ppi |
| 200m /ย 650ft | 1 ppi |
This is applicable to all digital photos, taken by any camera, including DSLRs or Mirrorless digital cameras
