We've been explaining "pixels" to others since the days of the IBM CGA monitor. Our articles and calculators
have appeared on many web sites over the years but now have a permanent home of their own here at pixelyzer.com.
If someone referred you here to get a better understanding of the concept of a "pixel," you are at the right
place. If you've already mastered the subject, our calculators and other resources are here
on the other pages of this site.
We'll start with a discussion of pixels as they relate to your visit here, I.E. the resolution and physical size of the monitor or other device you are using to view this page. This worksheet and a ruler or tape measure will help you begin to visualize the relationships of virtual and physical elements used to present images and graphics on modern digital devices.
Here is some information reported by your device. This information may sometimes be missing or incorrect due to software bugs. If it is obviously wrong, you can correct it by entering the correct values in the form.
Next, you may want to change the physical unit of measure for our pages:
Finally, using the information provided, this system will calculate the precise number of pixels per unit of measure and create an image of an exact measurement for you to measure/compare right on your display.
