How To Print Exact Size In Inches

⬇ Specify your screen size for calibration

inch cm

If you want to measure out the bodily size of a small object in inches or centimeters and you don't accept a real ruler at mitt, this virtual on-screen online ruler volition assistance yous. You can make the necessary measurements on any device that allows y'all to browse the web. This online app works on both computers with a big screen (laptops, PCs, monoblocks or smart TVs) and mobile gadgets (phones, phablets, tablets, east-ink readers). The maximum length of the ruler (fully visible when displayed on a sufficient screen) is twenty inches, or 50 centimeters (500 millimeters) for the metric scale option.

💁 How to use this online ruler

For the ruler to display correctly (i.e., in proportion to the actual concrete size), it must be calibrated. Yous tin can calibrate it in one of the following 2 ways:

📱 💻 📺 Set screen diagonal

This is the near reliable and easy way. Specify the size of the diagonal of your screen in inches ("). Enter this value in the input field located in the lower left corner of the ruler epitome. Then click the or press the button on the keyboard. You lot can also select the size from the drop-downwardly list (which opens when you lot click the button , which is adjacent to the numeric input field). This presents many of the most mutual options among users.

The diagonal of the current device's display, automatically detected past the browser, is . In most practical cases, this calculated value does not stand for to the real extent and is instead proposed for consideration as an approximate ane for consideration purposes. This circumstance is caused by the existing constraint imposed past the specifics of the interaction of modernistic web browsers (none of which has the functionality of providing web applications with access to information most the brandish's concrete parameters) with operating systems. Depending on the type and class of device, the likely fault varies in a range of up to several centimeters, or 1 inch. Appropriately, to the best possible, the reliability of the indications of the uncalibrated online ruler will differ from the standard. Nevertheless, the deviation may be minimal. In this case, the initially visualized ruler will be suitable for measurements that do not require loftier accuracy (especially when measuring small objects).

If you do not know the exact value of your screen'southward diagonal, yous tin can find it in the technical documentation fastened to the device, or only search the Internet for the model name.
If for some reason this information is hard to obtain and you have a standard plastic menu with you, you lot can utilise the 2d method. ↓
💳 Fit to the width of a plastic card

You can also calibrate the on-screen ruler using a bank payment bill of fare. Its standard width is 3.37 inches (3 3⁄8 inches), or 85.six mm (eight centimeters, 56 millimeters) for the metric measurement. For your convenience, the corresponding sign is plotted under the scale of the ruler. Alter the diagonal value in the input field until the edge of the plastic carte attached (oriented horizontally) to the screen coincides with the blackness stroke to the left of the icon.

Using this method in addition to the first method will permit you to decide the size of the display diagonal. To avoid the known inconvenience associated with selecting a number past successive manual input, bring it to the desired value using the vertical ringlet arrows that appear on the right side of the input field when yous hover the cursor over information technology (when using the virtual ruler on a PC).

📏🔧 How the ruler'due south actual size is accomplished

Based on the browser-defined screen meridian and width, the script:

calculates the diagonal in pixels (it does non matter if the number of virtual pixels on which the browser operates is the actual physical resolution of the display);
calculates the PPI (pixels per inch) of the screen: the resulting diagonally expressed diagonal is divided by the user's diagonal value in inches;
determines the length of the ruler in pixels, the respective existent l centimeters: the PPI value is multiplied past expressed in inches fifty centimeters. For inch scale, it is simply multiplied by twenty.

⚠️ ️Note

Keep in mind that the above instructions for setting upwardly the ruler are valid only when the following weather condition utilise:

Standard page calibration adjustment in your browser (this is true for desktop browsers). When the scale is zoomed in/out, the ruler calibration will shrink/stretch (forth with other elements on the page that are subject to transformation during scaling). This will lead to a significant distortion of the online ruler readings. If you often, for example, alter the font sizes on sites, be certain to prepare the scale to 100%;
