Vernier Caliper is a widely used linear measurement instrument with a least count of 0.02 mm. It is used to measure linear dimensions like length, diameter, depth.
It is Basic Instrument of measurement, consist of two types of scale –
The main scale and the Vernier scale that can slide along the main scale. Two types of measurement we can do, the first one is through external jaw (measure external dimensions) and another one is internal jaw (measure internal dimensions).

The main scale is graduated in millimeters or inches, or usually both in many cases. The Vernier caliper is made of either stainless steel or tool steel, depending on nature and application.
In order to measure dimensions like outer diameter, inner diameter, depth with External jaws, internal jaws, extension rod respectively, the simple steps are –
- See the main scale read just before zero of vernier scale like 8 mm
- Now, observe the vernier scale such like, which graduation like exactly meets with the main scale. In a simple term, check which line of main and vernier scale are meet or align. Let’s try to see 0.35 mm of vernier scale so your actual measurement is 8mm +0.35 mm = 8.35 mm
Vernier Caliper is Cheap, accurate, reliable and subjected to less maintains criteria. Follows some term given to help you to find you need this instrument or not?
The accuracy of Analog Vernier caliper is 0.02 mm which is fair enough for linear measurement. You can choose Digital Vernier Caliper if you need more accuracy up to 0.01 mm.
