How to Figure Out Photo Print Sizes for Your iPhone Pictures

Printing your favorite iPhone photos is a great way to capture memories and keep them close at hand. But do you have a ton of pictures on your iPhone that you want to print out and don’t know the best print size for each one?

This guide will help you figure out the perfect photo print size for your iPhone snaps to ensure they look their best!!

Short Answer

  • Open Lightroom and select a photo to print from the library.
  • Tap the down arrow in the upper-left corner and select Info.
  • The pixel dimensions are displayed at the bottom of the screen.

What Are the Standard Photo Print Sizes?

If you’re going to be printing your photos at the nearest print shop, you’ll likely want to know the standard photo print sizes. These are the most common print sizes that photo labs use, and they’re usually a safe bet if you’re not sure what to order:

  • 4 x 6 inches
  • 5 x 7 inches
  • 8 x 10 inches
  • 8.5 x 11 inches
  • 12 x 18 inches
  • 18 x 24 inches
  • 24 x 36 inches

Generally, if your iPhone photos don’t fall into one of these categories, you’ll either have to order a custom print size or crop your image to fit one of the standard sizes. If necessary, the print shop staff can help you with the cropping.

Which Photo Print Size Should I Use for My iPhone Photos?

Ultimately, the best photo print size for your iPhone photos will vary depending on the purpose of the prints.

For instance, if you’re just looking for a small snapshot to put in your wallet or scrapbook, share with friends, or hang up on your refrigerator, then a 4 x 6 inch print will work best. That’s because most iPhone photos have a ratio of 3:4, so they’ll fit nicely into a 4 x 6 inch print, and you’ll only have to crop the photo slightly on the edges.

However, if you’re looking to frame some of your photos or hang them on your wall, 8 x 10 or larger prints can be great options. Just be sure to leave enough space around the photo for a nice border and avoid cropping the subject too much.

How to Print iPhone Photos in Other Photo Print Sizes

If you want to print your iPhone photos in a size that’s not one of the standard photo print sizes, or if you have a special project in mind, it’s easy to order a custom print size. First, however, you’ll need to consider two things: the aspect ratio of your photo and the resolution.

Aspect Ratio

The aspect ratio is simply the ratio of the height to the width of your photo, and it’s essential to consider when ordering a custom photo print size. Most iPhone photos have an aspect ratio of 3:4, which is a common format for prints. However, some photos may be in 7:5 or 16:9 aspect ratios, so you’ll need to be sure to specify the aspect ratio when ordering a custom print size.

But since these aren’t standard print sizes, the photo print shop will likely have to crop your photo to fit the requested size. It’s best to do it yourself, so you can see how the final print will look, rather than leave it up to the photo print shop.

How to Crop an Image to a Standard Photo Print Size

If you want to crop your iPhone photo to a custom photo print size, there are a few ways to do it. The easiest and most common way is to use the default Photos app on your iPhone. Here’s how:

  • Open the Photos app and find the photo you want to crop.
  • Tap the Edit button.
  • Tap the crop icon (it looks like a square with arrows pointing inward and outward).
  • Click on the resize icon on the top right (it looks like multiple-sized squares).
  • Select the photo print size you want from the list on the bottom (the list will be different depending on the aspect ratio of your photo, but it’ll always include preset cropping ratios that include the standard photo print sizes).
  • Drag the corners of the crop box to adjust its size and position.
  • When you’re done, tap the Done button.
  • The cropped photo will be saved to your Photos app.

Resolution

Another thing to consider when ordering a custom photo print size is the resolution of your photo. This is simply the number of pixels in your photo, and it’s measured by printers in DPI (dots per inch). Resolution is important because it determines the print quality. The higher the resolution, the better the print quality will be.

Most iPhone photos have a resolution of around 300 DPI, which is fine for prints up to 8 x 10 inches. For larger prints, you’ll want a higher resolution photo, preferably at least 600 DPI.

However, if the resolution of your photo is too low, the photo print shop may not be able to produce a good-quality print since the pixels will be too large, resulting in a blurry or pixelated image. Therefore, you’ll want to choose a size that’ll show off your photo to its best advantage while still keeping the file size manageable.

If you’re not sure what the resolution of your photo is and want to know how large a print you can get with it, there’s an easy way to find out. Here’s how.

How to Check the Resolution of an iPhone Photo

Before getting to the resolution of the photo, you’ll first need to determine the pixel dimensions. While iPhones don’t show the pixel dimensions of a photo in the Photos app, you can use a third-party app, like Lightroom, to find them:

  • Open the photo in Lightroom.
  • Tap on the arrow next to Edit on the upper left, and click Info.
  • At the bottom of the screen, you’ll see the pixel dimensions of your photo.

Once you have the pixel dimensions of your photo, you can then use a resolution calculator to determine the DPI:

  • Open your iPhone’s Calculator app.
  • Divide the length of your image’s longest edge (in pixels) by the length of your desired print size (in inches).

For results higher than 300, you’re good to go. Anything lower, and you may experience some degradation in print quality, but up to 240 DPI is still generally usable.

If you’re not a fan of calculations, here’s a chart that gives you the approximate resolution you need for different print sizes:

Print SizeMinimum Pixel Dimensions (300 DPI)
3 x 51500
5 x 72100
8.5 x 113300
12 x 185400
18 x 247200
24 x 3610,800

In Conclusion

While there are a few things to consider when ordering a custom photo print size from your iPhone photos, it’s not too difficult. Just be sure to crop the photo to the correct aspect ratio, and make sure the resolution is high enough for the print size you want. With these tips in mind, you’ll be able to order top-notch prints of your favorite iPhone photos!
