How to Use Ruler.info

Using Ruler.info is straightforward, but proper calibration is crucial for accurate measurements. The calibration process involves matching the on-screen ruler to the actual size of a known object.

Follow these steps to get started:

  • Step 1: Measurement Conversion

    Easily convert between different units of measurement without calibrating your screen. Place the marker on your known measurement of any unit and all other units of measurement will be shown: centimeters, millimeters, and inches.

  • Step 2: Calibrate Your Screen Before Measuring

    Calibration is a vital step to ensure the accuracy of the online ruler. Follow these steps for proper calibration:

    • Select an Object for Calibration: You can use a credit card, US $1 bill, a piece of A4 paper, or a piece of Letter size paper. These objects are commonly available and have standard sizes.
    • Place the Object Against Your Screen: Align the selected object with the on-screen ruler.
    • Adjust the PPI (Pixels Per Inch): Use the input box or the plus/minus buttons located at the top right corner of the website to adjust the PPI. Adjust until the on-screen representation matches the actual size of the object. This step ensures that the ruler is accurately scaled to your specific screen size.

  • Step 3: Measure Your Object

    Once calibrated, you can start measuring. Choose the horizontal or the vertical ruler. Place the object you want to measure against your screen. Align the edge of the object with the starting point of the ruler and read the measurement at the other edge. Mark the measurement with the cursor and lock it on the ruler with a click. This method works for a variety of items, from small objects like jewelry to larger items like documents or craft materials. The measurements will be shown in different units without recalibrating your screen.
