Let’s start!


Types of Calipers

Calipers are classified into six categories. They are all capable of taking the essential measures. The only difference is the read-out. They’re all right here.

i. Digital Caliper

Digital calipers are the latest caliper innovation with their own advantage. Instead of a rack and pinion, an inbuilt microprocessor calculates the jaws’ location. Then, it displays the result on a digital display, such as an LCD screen.

The digital caliper looks like a Vernier caliper, but the technology employed makes it more expensive. Moock Digital Caliper models are examples of the advanced digital calipers, especially the Moock MK DC 01 model, which is a cult favorite.

ii. Vernier Caliper

Vernier calipers have dual scales on the top and bottom that indicate imperial and metric units. They can measure outside diameter and inside diameter, as well as depth. These are most commonly found in a school.

iii. Dial Caliper

Dial Calipers have a dial with an indicator needle. This measurement is then coupled with the scale reading running along the caliper’s beam.

The dial caliper is used for measuring outside and inside diameters, steps, and depth.

iv. Jenny Caliper

Jenny calipers are sometimes known as hermaphrodite calipers or odd leg calipers. These are used to draw a line from the edge of an object. They are also used to realize the center of a workpiece.

v. Spring Joint Caliper

The screw and nut can be turned to adjust the leg spacing of this caliper. They can be used to measure inside and outside diameters.

Spring joint calipers lack a graduation scale and must be checked against a ruler or micrometer.

vi. Micrometer

Micrometers specifically measure small distances down to 1/1000 mm. They are commonly used by professional mechanical engineers for measuring objects, block thickness, shaft diameters, and slot depths.

Buying Guide for the Best Caliper

If you’ve been paying attention, you’re already familiar with some great calipers. But don’t just pick any of the above models at random. You might regret getting a caliper if you don’t understand the basics. It would help if you also determined the compatibility of the caliper for your intended use.

We will discuss some crucial variables to consider when purchasing the best caliper for your toolbox. The following factors define the overall performance of a caliper. Before you buy a caliper, be sure it fits these criteria:



Stainless steel, carbon fiber, and plastic digital calipers all have benefits and drawbacks. In digital calipers, stainless steel is the most common material. It’s heavy and resistant to liquids such as oil and water and dust. They are also the priciest.

Carbon fiber is strong and lightweight. Its closely woven carbon polymer fibers are as strong as metal yet weigh less. It is less corrosion resistant than stainless steel body and may deteriorate faster if exposed to water, dust, or UV rays. Carbon fiber calipers are usually less expensive than stainless steel brakes.

Plastic calipers are often the cheapest and lightest but also the weakest. Professionals and DIY enthusiasts rarely use plastic digital calipers.

Finally, composite digital calipers are made of a blend of conventional plastic and carbon fiber that fall someplace between the two in terms of strength and cost.


Measurement Accuracy

One of the key benefits of digital calipers is their accuracy and measurement range. For example, a digital caliper has a measurement range from as small as 0.01 inches (0.25 mm) or 0.0005 inches (0.01 mm) depending on the caliper’s standard and the operator’s skill level.

The precision of digital calipers is influenced by the digital elements that translate the gap between the inside and outside measuring jaws. Certain hardware components can also help.

A digital caliper constructed of polished stainless steel usually has smoother measuring jaws motion. A large, textured driving wheel may enable making finer modifications by providing increased traction for the fingers. The precision and measuring range of a pair of digital calipers depends on both the user’s aptitude and the unit’s individual choices.



Calibration is the ability of an instrument to achieve results as close as feasible to ideal outcomes. Calibration is the intricate process of comparing an instrument’s zero value to a calibrated sample. A properly calibrated caliper can contribute to acquiring extremely precise findings.

Many digital calipers come pre-calibrated from the manufacturers, saving the time and money of the users. But only a few options require manual calibration that professionals can calibrate as required. So, if you are a beginner, go for the pre calibrated digital calipers as your first pair.


Reliability and Durability

You should pay close attention to the maker’s warranty period. The warranty period is a fantastic way to judge the longevity of a digital caliper. If the vernier caliper is exceptionally reliable, the manufacturer will offer a longer warranty period.

Next, assess the digital caliper’s durability. The durability of your digital caliper will ensure that it lasts for many years and uses. Firstly, the digital caliper should be made of metal. Because metal tools are resilient to falls.

Metal digital calipers, like all metal tools, are susceptible to corrosion. Keep your digital caliper clean to avoid rust. Water damage might also affect the caliper rating digital display. Look for digital calipers with an IP rating and a solid structure to avoid water damage.

You can also check for the advanced on-site sensor. This Advanced Onsite Sensor ensures caliper is oil-resistant, water-resistant, and dust resistant. Moreover, check for electromagnetic inductivity sensors.


Measurement Units

Various digital calipers offer varying degrees of versatility. The digital caliper’s measuring units demonstrate its versatility. Inches are the most often used measurement unit. However, some measurements require millimeters or even fractional units.

The digital caliper will switch between inches, millimeters, and fractions, thanks to unit conversion. These features to convert units will make the digital caliper handy in a wide range of circumstances, instruments, and tasks.

Fortunately, most digital calipers now have all three measuring modes with three different units. So, if you come across a digital caliper that lacks these unit conversion features, we recommend going with a different model with unit conversions instead.


Battery Life

As you may have noticed from our product reviews, the battery life of a digital caliper is critical. So, when choosing a digital caliper, consider its battery life. The digital screen on digital calipers is useful, but they require batteries. The digital caliper is worthless without batteries or poor battery life.

Look for digital caliper models with substantial battery life to ensure a long-lasting product. Consider the digital calipers that automatically shut off. Although these features may be annoying if they turn off while using the digital caliper, they preserve battery life.


Depth Gauge

The depth gauge is unquestionably the most important feature of a digital caliper, allowing us to accurately measure a hole’s depth. This feature is also useful for measuring material thickness. Thus, check to see if the caliper you want has a sturdy depth gauge for ensuring consistent measurements.


Inside/Outside Jaws

The inside/outside jaws of a caliper measure an object’s internal and external dimensions. Nowadays, most digital calipers on the market have delicate measuring jaws that can be easily destroyed. So, while selecting a digital caliper, ensure the measuring jaws are made of robust material.


Locking Screw

The locking screw ensures that the measuring jaws are properly locked for precise measurements. However, some digital calipers come with low quality locking screws that can lead to achieving false results, so be careful.



The longer the digital caliper, the more efficient it will be. Buying a small/standard caliper won’t help a professional. Beginners can achieve great results using a caliper with a length of six inches.


LCD Screen

As measuring equipment, an ideal digital caliper should clearly display the readings for the user. Neiko and Mitutoyo have a large LCD display, which is rare in most calipers.


Ease of Use

Taking precise measurements can be tiresome. Therefore, most customers look for easy-to-use digital calipers with a large screen. Thankfully, features like polished stainless steel components and a large, textured thumbwheel help make the digital calipers more user-friendly.

A large LCD screen and a lock screw are just a few of the extra features that make the digital calipers easier to operate.


IP54 Protection

The best digital calipers can be used in undesirable settings for electronics, such as machine outlets or open air. If this is a pattern, make sure the digital calipers you choose can withstand the surroundings, which is where an IP (or ingress protection) ranking comes in. IP test is a third-party certification that evaluates the environmental resilience of electronic components.

The first number after “IP” reflects the digital caliper’s solids resistance, and the second number represents its moisture resistance. The standard for a digital caliper is IP54. The “5” indicates it may resist muck, whereas the “4” indicates it may resist water from all directions. If your digital calipers will be used in harsh conditions, such as outdoors, look for an IP54 safety certificate.


Caliper Maintenance Tips

  • Wipe the measurement jaws of the caliper and the workpiece’s surface to avoid measuring errors due to dirt or dust.
  • Clean the digital calipers after every use.
  • When not in use, place the caliper in its protective case.
  • Use your caliper on solid objects.
  • Check the calibration and fine adjustment periodically and recalibrate as needed.
  • Never drop or throw your digital caliper.
  • Avoid laying the caliper on the bench where it can be damaged or wet.
  • Avoid putting the caliper in other debris.
  • Don’t exceed the measurement range of the digital caliper.
  • Don’t use a caliper in place of other tools, such as pry bars or screwdrivers, as such actions affect the quality of the caliper.


Final Thoughts

A caliper can be an excellent substitute for a variety of tools. Furthermore, because it is a precise measuring tool, its accuracy is unquestionable.

After reading our reviews of the best calipers and the detailed buying guide, we hope that you will find it easy to choose the finest caliper for your needs. Just remember to keep the crucial aspects mentioned above in mind, and you’ll be able to discover the perfect caliper for you.
