Realtors and agents want high-resolution images, whether it's for print or uploads. This is why, for this guide, we're sharing how many pixels per inch can produce high-quality image resolution. I'm also teaching how real estate photographers and editors can determine the necessary PPI depending on the client's output requirements.
The number of pixels per inch differs on various displays because pixels have varying sizes. There are multiple answers depending on what you're working on, as well as the screen type. However, it's common to have 96 pixels per inch on display or print.
Clients or your personal work might have different requirements. For this reason, I've going to discuss how PPI works in real estate photography and what you can do to compute the pixels per inch.
A pixel serves as an area of color or illumination on an image or screen. It's also a unit of measurement used in web and graphic design. Since it varies in size, a good starting point for a display is 96 pixels or more.
On the other hand, pixels per inch (PPI) refers to the measurement of resolution in a digital picture or display device. It identifies the fixed number of pixels a screen can display or a photo's pixel density or amount of detail.
The PPI also indicates how many pixels are there in an inch, which is 96 pixels or greater. It specifies the number of pixels available vertically and horizontally. For instance, a real estate photo with 300 pixels down and 300 pixels across translates to 300 x 300 PPI.
When a client wants to change the resolution, you need to modify the standard 96 into the necessary number of pixels in every inch of the picture or display. This is why it's important you know how many pixels are there in an inch to resize images properly.
Since the number of pixels per inch may differ and go beyond 96 PPI, I'm helping you do the simple math to determine the PPI of an image or display.
Use this formula:
PPI = (√(w² + h²)) / d
Where:
W = width resolution in pixels
H = height resolution in pixels
D = diagonal size of the display in inches
Suppose a real estate agent wants to display 4K house tour videos on a 60-inch television. This ultra-high definition display translates to 3840 x 2160 pixels.
Now, considering the variables and following the formula above:
PPI = (√(w² + h²)) / d
w² (3840² = 14,745,600)
w² (2160² = 4,665,600)
14,745,600 + 4,665,600 = 19,411,200
√19,411,200 = 4,405.814
4,405.814 / 60 = 73.43
Thus, to meet the requirements of your clients, you need to work on 73.42 PPI to display 4K videos on a 60-inch television.
A case study shows that image-based content marketing can significantly boost overall organic traffic by 175%. However, your work as a real estate photographer doesn't end at styling the scene or taking photos.
Post-processing real estate images is also a crucial part of the job, and this includes applying the correct pixel sizes depending on the platform or material. While the industry standards for PPI may change in the future, these are the most common PPI values you can apply in your works.
About 93% of consumers consider visual appearance a crucial factor when purchasing something. As a photographer, agents will rely on your expertise to provide the highest image quality. However, it's not enough that you use the best lens for real estate photography or apply the appropriate camera settings.
When editing photos in Lightroom, you can also work on the PPI values to further enhance images. Make sure to calibrate your monitor so that your outputs have accurate details.
Another option is to change the pixels per inch value in Adobe Photoshop since the program sets up the PPI resolution once you create a new document.
Dots per inch refers to the number of individual lines put in an inch, corresponding to the output resolution. The DPI uses tiny dots per inch to improve detail and overall quality, whether print or web uploading.
For Mac users, locate your file, click on it, and open the file info, which contains the pixel dimensions. If you're using Windows, right-click on the file, select Properties > Details, then look for the Dimensions.
The number of pixels per inch varies on the display size. However, the most common contain 96 pixels in an inch of the display. You can follow my computation guide to determine the PPI to ensure you can provide the best image resolution for real estate visuals.
