## Actual Size Ruler

At this distance the individual pixels can not be resolved while simultaneously maximising the viewing area. So the ideal set size can be determined from the chart below by measuring the distance from where the watcher would sit to the screen in centimeters or inches , dividing that by 4, and comparing with the screen heights below.

If the user is replacing a standard definition TV with an HDTV this implies that the best visual experience will be with a set that is twice as tall as the standard definition set. Cost and budget also limit screen size.

The TV image is composed of many lines of pixels. Ideally, the TV watcher sits far enough away from the screen that the individual lines merge into one solid image. The watcher may sit even farther away and still see a good picture, but it will be a smaller portion of their visual field. However, note that viewing behavior is dependent on screen size.

Common screen dimensions are listed in the table below. If the display is not listed, then the following equations can be used.

Note that D is the diagonal in centimeters or inches , W is the width in pixels , and H is the height in pixels. From Wikipedia, the free encyclopedia. For the number of pixels measured vertically and horizontally per screen, see Display resolution. This article has multiple issues. Please help improve it or discuss these issues on the talk page.

So later, we developed an online ruler by ourselves. It not only improves the accuracy of the measurement, but also has a scale of inches and centimeters so that it can be used in our work. If you are like us, you need a precise online ruler to measure the product size, i believe this online virtual ruler can also meet your needs.

I am very happy that many people like our online ruler, also i am very excited to review all the comments from all the visitors. This ruler measure in two different units of length, inches on one side English ruler and centimeters on the other side metric ruler.

A metric ruler is use to measure centimeter cm and millimeter mm , the centimeter is a unit of length in the International System of Units; An English ruler provides incremental measurements in inches, with each inch further divided into smaller fractions. Read an English ruler using fractions of an inch. The distance between any two large numbered lines is 1 inch. Observe the much simpler metric rulers.
