What is the image resolution?
Understanding some fundamental concepts is necessary to comprehend image resolution. Understanding what makes up an image, i.e., pixels.
What is a Pixel?
Pixel stands for picture element. The smallest element that can display on a screen is called Pixel. When you zoom in on an image, the tiny, tiny square appears on your screen. This is how you get the Image on your screen.
What is an Image Size?
A picture’s size is the sum of the number of pixels stacked in its width (w) and the number of pixels stacked in its height (h). This is also called the Image’s dimensions.
Image Size = Width (w), x Height(h) of an image
A 1920 X 1080 file size would be an image with a width of 1920 pixels and a height of 1080 pixels. Because 1 pixel is an image unit, it is measured in pixels. The total number of pixels in a 2073600 pixel image is approximately 2 megapixels (2 MP). If your phone camera has 2 megapixels, it can capture images with a dimension of 1920 x 1080 pixels.
NOTE: Image Size does not equal Image File Size. Image file size refers to the amount of storage space an image takes up on your computer’s hard drive. This measurement is in bytes, which are usually kilobytes or megabytes.
What is Image Resolution?
Image Resolution is a term people use to describe the clarity of an image. People assume that a photo with more pixels means it has high resolution.
- The number of pixels comprises the Image’s height and width (dimensions of the Image.).
- The screen size on which the Image is displayed (normally measured in inches).
Image resolution can be measured in pixels. It’s not just the pixels in an image but also the dimensions of those pixels. You need to know the screen size on which an image will be displayed. This will determine the Image’s true resolution.
What is the image resolution unit for measuring?
Images resolutions are measured by pixels per inch (PPI). This unit is used to measure digital image resolution. The number of pixels per inch, or PPI, is the number of pixels arranged in a 1-inch square box. It indicates how many pixels are arranged by width (column), height (row), and so on. This is also called Pixel density or Pixel Density. It is the same thing as Image resolution.
How do you check the resolution of an Image?
You can quickly check the resolution of images on your computer.
In Windows: To verify the resolution of an image on the Windows Operating System, right-click the Image to be checked, then go to Properties. Next, scroll down to the Image section.
In Mac: It is much easier and more precise to check the image resolution on Macs than it is for Windows users.
It’s easy—double-click on the Image to open it using the default “Preview” option. Next, click “Tools” and select “adjust the scale.” A window will appear displaying the details of the pixels and the resolution so that you can see the Image in the above Image. The image resolution in the example above is 72 PPI, and the Image has a dimension of 360 x540 pixels.
This pop-up box allows you to reduce the image resolution. You can, for example, replace 72 with 50 in the example above, and the image resolution will be reduced to 50 PPI rather than 72 PPI.
PowerPoint: Setting pixels
I explained initially that a default PowerPoint presentation is 13.333 inches by 7.5 inches. PowerPoint 2013: Click Design from the normal PowerPoint menu and then click Slide Size.
There are three options available when the button opens.
- Standard (4:3)
- Widescreen (16.9)
- Slide size can be customized
To enable the Custom Slide Size, click on the 3rd option. You will be presented with this form:
If the user wishes to create a slide or slideshow of 1920×1080 pixels in size, just enter
1920px
Enter the width
1080px
At the height field.
This will automatically be converted into centimeters or inches.
To close, click OK. All slides in your current presentation will be this size. Now you can add slides and information to the system.
How do you convert low resolution image to a high resolution image?
PowerPoint cannot scale up a low-resolution image. It is strongly recommended that you start with a high resolution image in PowerPoint. There are, however other options available for scaling up images.
Can I choose a default resolution for PowerPoint images?
PowerPoint has a default image compression. You can set it to one of these options:
- 220 PPI
- 150 PPI
- 96 PPI
Check and adjust your default image resolution/compression option:
- Open PowerPoint file
- Go to File
- Select Options
- You will find Advanced within that menu.
- Quality and size of images
- Select the appropriate PPI setting in the dropdown menu. Choose from 220ppi, 150ppi, or 96ppi.

Maximum Size
Let’s start with the topic of maximum slide sizes. This information is essential if you plan to print your creation on a large format printer or display it on a monster projector. The maximum size of a PowerPoint slide at the moment is:
142.24 x 142.24 cm
Conclusion.
Image resolution is not an easy topic to discuss. Now you understand image resolution and ensure that your next presentation does not include pixelated images.
