How to Read Vernier Calipers:

  • To find the primary measured value on the scale, you first note the main scale measurement following the zero line on vernier scale. In the case of the example below, the zero of the vernier scale reads just past the 28mm mark. Meaning the measurement is 28._? Now you need to find the decimal value.
  • To find the decimal value on the scale, find the line on the vernier scale that most closely lines up with the line on the main scale, and add the number from the vernier scale to the overall measurement found in step 1. In the case of the example below, the vernier scale and main scale match up at the 6 digit, meaning the overall measurement is 28.6mm.
