Online Ruler | Virtual ruler (inches, cm, mm)

Sometimes we need to measure the length of different objects and don’t have a ruler nearby, the online ruler can be the perfect solution as it is a 100% effective utility. This virtual ruler allows you to have a life-sized ruler to measure the length of small objects in inches centimeters or millimeters.

To use the digital ruler, you just have to select the desired unit of measurement: inches (green color) = IN and centimeters (gray color) = CM. It is available at the bottom right corner of the ruler, as shown in this image.

Only calibration of the ruler is missing, by entering the diagonal or size of your screen. There are two options to do this:

• You can enter the number directly and then click on “Calibrate,” as shown in this image.

• Use a credit card, debit card, or similar as a reference. The longest side measures 3.37 inches (3 3⁄8 inches) or 85.6 mm (8 centimeters, 56 millimeters). Place the card directly under the ruler at the left end and adjust the diagonal measurements until the painted mark on the ruler aligns with the right edge of the card, following the visual reference provided in the following image.

If you don’t know the exact value of your screen’s diagonal, you can find this information in the technical documentation of your device or directly search the internet for the diagonal of your device’s screen.

Once the online calibration of the ruler is completed, you can start using it to measure the length of objects to your liking. This virtual ruler is especially useful for measuring small or medium-sized objects, as it allows for high precision in measurements.
