DIY enthusiasts love to work with a lot of instruments while building their own stuff. Working in their workshop with instruments to create artifacts, wood workings etc., will require precision measurement in all cases. A device that can be used to measure anything with precision is called a caliper. Any object can be subjected to measurement with a caliper. For a digital caliper you can read the measurement through a digital display. We just have to insert the object between the jaws of the caliper and screw the sides of the jaws together to get a reading. Digital caliper tool is useful for carpentry and making wooden artifacts to correct measurements.

Dial calipers have existed for a long time, and digital has made its way into the market for accurate measuring techniques. In most cases, we preferred digital ones as they gave measurements to the point and did not require tuning or adjusting. The number on display could be easy to read without having to decide the exact measurement ourselves. The electronic digital caliper can last long and will require just replacement of batteries after starting to use. We have collected a list of calipers from the market, and we will elaborate on the features that we liked after using each product.

Buying Guide

We covered all brands that stood out while testing a digital caliper for home uses. The most likely features and our experience due to each feature elaborated in detail. With this we move on to the buying guide where generic questions and answers will clarify why to choose a digital caliper over traditional one. We also cover brands that make the best digital calipers for sale.

What is a Digital Caliper?

A digital caliper is a measuring instrument that has two jaws and a probe. The object to be measured should be kept between the jaws and measured by tightening. This digital dial caliper has a digital screen to give out the values measured. Digital inside calipers measures internal diameter.

Why do you need a Digital Caliper?

Digital calipers mainly used by people for the accurate measurement of the objects. Most DIY projects require measuring and fitting joints with perfect accuracy. While in case of regular metal calipers, accuracy goes for a toss and we get only near values as we have to self-read ourselves from the ruler.

How does a Digital Caliper work?

Any object to be measured is kept between the jaws of the digital caliper. We have to use the thumb roller to bring the right-side jaw together with the first jaw to hold the object tightly. After this, the caliper can be switched on and the value will be displayed on the screen. We can convert to the required measurement unit by pressing the button on the control panel.

How to setup a Digital Caliper?

Calibration is an important step to know whether our caliper is working fine or not. We can tightly close the caliper jaws to see if zero is being displayed on screen. An alternate way is to use gauge blocks. A 6-inch digital caliper can be calibrated by placing a 1-inch, 4 inches block between to see if correct values are given.

How to use a Digital Caliper?

  • For outside measurements, keep the jaws tightened around the object and read the value on display.
  • For step, the bottom jaw will be on step and the other jaw will make contact with the object to learn the measurement. 
  • Inside measurements can be taken by using the small jaws on top, placing them inside the object to get values. 
  • For depth, the probe should be inserted into the hollow object using screws and read the value on screen.

Types of Digital Calipers

General Purpose Calipers

The types we have seen till now are the general-purpose calipers. They are used for woodturning, carpentry, and automotive uses. It consists of an electronic digital display mostly to get accurate readings. It is best to get this for DIY purposes at home. Workshops can hole this caliper with storage boxes correctly.

Specialty Calipers

Specialty calipers used for different types of measurements. They are either available in electronic or vernier style. The different specialty types are offset, point, tube thickness groove, long jaw calipers. Each style used for different purposes. Different brands like Mitutoyo, Kerley, Gaging create specialty calipers for unique uses.

Who Makes the Best Digital Caliper?


They have been producing calipers for long and have specialized in creating them with good material. Waterproofing property is their speciality and it should be present in all calipers to prevent dust and water entry to bring down its life. Mitutoyo has even created a solar version to save battery usage.

Harbor Freight

Amazing calipers with good features have been created by Harbor Freight. Most of their calipers are 6 inches and contain a good digital display to give out the readings. They have been pioneering in creating the best cheap digital caliper. Dial type calipers are also available from Harbor Freight for convenient usage.

Digital Caliper Uses and Applications

  • Useful for measuring inside, outside, step and depth of objects in DIY projects.
  • Carpentry
  • Woodworking
  • Polishing silver
  • Automotive parts machinist
  • Medical instruments
  • Locksmithing
  • Educational institutions
  • Research applications
  • Comparative measurements
  • Extremely accurate measurements

Uses of small digital calipers are mostly seen in workshops at home and are preferred by DIY enthusiasts.

How to Reset a Digital Caliper?

A digital caliper can be reset or set to zero by pressing the zero button on the panel beneath or just above the LCD screen. It is best to keep the measurement at zero each time while taking a new one. This is the main step in calibration. If it is not reset, then inaccurate measurements will be displayed thereby confusing all DIY projects.

Dial vs Digital Caliper

Dial caliper consists of a rack and pinion and a gear set inside. This helped in moving the dial in increments of one thousandth of an inch. No batteries required and will work even when damp.

Digital caliper on the other hand consists of jaws and a probe. This can be used to measure inside, outside, depth and step measurements. Requires battery for screen and should be waterproof.

Micrometer vs Caliper

Calipers can be used for measuring inside, outside, depth, and step for most objects in an accurate method.
Micrometers are also the same; however, the small difference is that they can be used for more specialized measurements like outside or inside dimensions only. They are built with specialized jaws.

Digital Caliper Care and Maintenance Tips

  • Keep it in a protective case after each use to prevent dust and dirt.
  • Do not immerse in water for best results.
  • Brush off any dirt to make the sensor work better before each use.
  • Try using it for the purpose mentioned only.
  • Avoid pairing the digital caliper with any other tools like cutting machines, files, drills, etc.

How to Choose a Perfect Digital Caliper?

After detailed information about digital calipers, you may now decide what to buy for your workshop. Here are the main considerations of the digital calipers while buying.

Big Digital Display

A digital caliper set should come with a good and large LCD screen to view the numbers after measurement. The display should be visible even during daylight and we should not have any problems like numerals being too small. Digital display plays the main role as we get accurate measurements without much margin of error. The display also should be placed at the correct location just above the main jaw to view easily.

Buttons on Panel

We should have buttons to control our digital micrometer caliper. To bring the measurements back to zero, we should have a zero button. To switch between units of measurement a button should be given. An on/off button is mandatory to save battery life. The units in specific should be displayed between inches, mms and fractions. Choose calipers that consist of at least these three buttons to have a smooth operation.

Material Used for Build

Stainless-steel should be used in construction as they give better and stable working. Polished stainless-steel can also be opted for a more stylish look and the jaws move without any hindrance or friction. Plastic digital caliper can become flimsy and may not be strong enough to give precision readings at all times. The knobs on the roller should have smooth edges to move with comfort.

Battery Provided

Make sure the caliper comes with batteries in the box. If not, then most calipers may be dead on arrival. Few brands give extra batteries along with the box as a gift. If we get such calipers, then we need to buy batteries for years together. Switch off the caliper when not in use for saving the battery. Automatic on/off is also a feature to be noted while buying the best digital calipers for machinist.
