The Resolution: A Definition

The resolution of a digital image is the number of pixels per unit length, usually in millimeters. You’ve seen it before – if you think about your phone or computer screen, how big is one pixel? It’s so tiny and hard to see that it can’t be measured! However, when we talk about resolutions in photography and videography, we’re talking not just about the size but also the quality.

There are two main types of resolutions: one is called ‘resolution’ and the other is called ‘pixel density.’ Resolution, when used for photography or film-making purposes, refers to the number of pixels on a screen (e.g., 1080p). Pixel density means how many pixels there are per inch (e.g., 300ppi).

A high resolution can give you crisper images because it packs more information in each pixel – think about cramming as much information into your suitcase as possible before leaving for vacation! It does not necessarily mean that an image with higher resolution will be clearer than another image with lower resolution; this depends on everything from lens quality to sensor size. A low pixel density can cause an image to be blurry, but it will still take up less space on your computer or phone.

In order for you to enjoy a higher level of detail in large prints and view images at their best quality, we recommend using photos with high-resolution (at least 300 ppi). For web use and viewing on mobile devices, resolutions between 72ppi and 200ppi are sufficient when viewed from the typical distances.

What is Image Resolution?

An image that is 640 pixels wide by 427 pixels tall has a resolution of 640 × 427 or 273,280 pixels. Since the photo contains just over 200 hundred thousand pixels, it is not even considered a “1 megapixel” image. Resolution in a digital camera is often measured in megapixels, which is just another way of expressing the image resolution.

The solution to this question depends on everything from lens quality, sensor size, and pixel density. A low pixel density can cause an image to be blurry but it will still take up less space on your computer or phone. In order for you to enjoy a higher level of detail in large prints and view images at their best quality we recommend using photos with high-resolution (at least 300 ppi).

For web use and viewing on mobile devices resolutions between 72ppi and 200ppi are sufficient when viewed from the typical distances. If you’re unsure what resolution is right for you, talk to us!

What is Display Resolution?

Monitors have display resolution, also known as pixel resolution, which are measured in pixels per inch (PPI). The greater the number of pixels on a screen, the clearer and more detailed an image will be. For example, a standard 13-inch laptop display has approximately 100 PPI whereas large computer monitors with 27 inches have about 150 PPI or higher.

The easiest way to think of PPI is that it determines how many dots can fit into one square inch:

  • 100dpi = 100px /in²
  • 150 dpi = 75px/in²
  • 200 dpi= 50px/in²

To get this calculation for your monitor you’ll need two bits of information: its diagonal size in inches and what kind of material it is.

We often hear about HD, FHD, Ultra HD, and more when monitor is mentioned. An HD display has 1920 x 1080 pixels.
