As of my last knowledge, iOS on iPhone/iPad doesn’t provide built-in features to directly view the DPI (dots per inch), height, and width of an image in the default Photos app. However, you can use third-party apps to access this information. Here’s how you can do it:
Select or import the image/desired photo you want to analyze.
Look for an option to view the image’s metadata, which should include information about its dimensions (height and width) and possibly the DPI.
3. View Image Details:
Once you’ve loaded the image into the app, you should be able to access detailed information about the image, including its physical dimensions and resolution.

DPI (dots per inch) is a frequently misunderstood term in the world of digital imaging and printing. Many common misconceptions surround DPI, leading to confusion among photographers, designers, and general users. In this article, we’ll address these misconceptions and shed light on the truth behind DPI to help readers gain a better understanding of its role and significance.
Myth 1: Higher DPI Always Means Better Image Quality
Truth: While a higher DPI is generally associated with better print quality, it’s not the sole factor determining image quality. The quality of a printed image depends on various factors, including the printer’s capabilities, paper quality, and the original image’s resolution. Increasing DPI beyond the printer’s capabilities won’t improve image quality.
Myth 2: DPI Matters for Images Displayed on Screens
Truth: DPI is primarily a print-related term and does not directly impact images displayed on screens. The screen’s resolution is measured in PPI (pixels per inch), not DPI. For screens, what matters is the image’s pixel dimensions and the screen’s PPI. DPI only comes into play when you’re preparing an image for print.
Myth 3: You Can Increase DPI to Enhance Image Quality
Truth: You can’t magically enhance the quality of an image by increasing its DPI without also increasing its pixel dimensions. Increasing DPI while keeping the pixel dimensions the same will only make the image appear smaller when printed and won’t add more detail.
Myth 4: All Images Should Be Set to 300 DPI for Print
Truth: The ideal DPI for print varies depending on the type of printing and the viewing distance. For standard printing, 300 DPI is often recommended for optimal results. However, large-format printing (e.g., billboards) may use a lower DPI because the viewing distance is greater. Always consider the intended use and consult with your print service provider for DPI recommendations.
Myth 5: DPI Can’t Be Changed Without Losing Quality
Truth: While increasing DPI without increasing pixel dimensions can’t add detail, you can decrease DPI without losing quality. Reducing DPI for large-format prints, for instance, can result in smaller file sizes and still yield acceptable quality if done within reason.
Myth 6: DPI Is the Only Factor Affecting Print Quality
Truth: DPI is just one of several factors affecting print quality. Other factors, such as color accuracy, file format, compression, and printer calibration, also play a significant role in the final output quality.
Myth 7: You Must Always Match DPI Settings Between Images and Printers
Truth: It’s not always necessary to match the DPI settings of an image exactly with those of the printer. Most modern printers can resample images to their native DPI during printing. However, it’s essential to ensure that the image’s DPI is within the printer’s acceptable range for optimal results.
Understanding DPI is critical for anyone involved in digital imaging and printing. By dispelling these common misconceptions, readers can better grasp the importance of DPI and use it effectively to ensure high-quality prints while avoiding unnecessary confusion and mistakes in their projects.
VIEW IMAGE METADATA INCLUDING DPI WITH THIRD-PARTY APP:
There are third-party apps available on the App Store that can display image metadata, including DPI, if available in the image file. Our App “Exif Viewer by Fluntro” can provide you with detailed information about an image’s properties, including resolution and DPI.
DPI (dots per inch) and PPI (pixels per inch) are terms frequently encountered in the world of digital imaging, design, and printing. Understanding the difference between these two terms is crucial for ensuring the quality of your digital content, whether it’s for screens or print. In this comprehensive guide, we’ll explain the distinction between DPI and PPI, and when to use each term to achieve the best results.
DPI and Its Role in Printing
What Is DPI?: Begin by defining DPI as “dots per inch” and explain that it is a measure of print resolution.
Printing Process: Describe how DPI relates to the physical printing process, where printed images are created by placing tiny dots of ink on paper. Emphasize that higher DPI results in finer, more detailed prints.
When to Use DPI: Explain that DPI is primarily used when preparing images for print materials such as brochures, flyers, posters, or any physical medium.
Recommended DPI Values: Mention typical DPI recommendations for various types of print work, such as 300 DPI for high-quality color printing and 600 DPI for professional photo printing.
PPI and Its Role in Screen Display
What Is PPI?: Define PPI as “pixels per inch” and explain that it measures the pixel density of a digital image for display on screens.
Digital Displays: Describe how PPI is relevant to digital displays, where images are composed of pixels, and a higher PPI means a sharper and more detailed display.
When to Use PPI: Explain that PPI is used when creating digital images, graphics, or designing for screens, including websites, mobile apps, and computer monitors.
Common PPI Values: Provide examples of common PPI values for different devices, such as 72 PPI for web graphics and 300 PPI for high-resolution screens like Retina displays.
Clarifying Misconceptions
Myths about DPI on Screens: Address common misconceptions, such as the belief that higher DPI settings on screens always result in better image quality.
Resolution Independence: Explain the concept of resolution independence in digital design, where images can be scaled without loss of quality based on screen PPI.
Practical Considerations
Image Editing Software: Mention how image editing software allows users to adjust both DPI and PPI settings. Provide examples of when to change these settings based on the intended use of an image.
Image Conversion: Explain how to convert between DPI and PPI when needed, considering the physical size and pixel dimensions of an image.
Design Best Practices: Offer best practices for designers and content creators on when to use DPI or PPI, depending on the project’s output, whether it’s print or digital.
DPI and PPI are fundamental concepts in the world of digital imaging. Understanding their differences and knowing when to use each term is essential for achieving the desired image quality, whether you’re designing for print or digital screens. By applying this knowledge, you can create stunning visuals that meet the specific requirements of your projects and ensure your content looks its best, whether in print or on screens.
