Best Dial Caliper

A dial caliper is a measuring tool mostly used by machinists, mechanics, and woodworkers. Dial calipers are extremely versatile and can make a wide range of measurements. It has to have many qualities to be the best dial caliper, which we will discuss here.

One important fact about dial calipers is that they have two scales with a dual reading mechanism. One scale measures the inside dimension of an object, while the other scale measures the outside dimension.

For example, if you measure the thickness of a piece of wood using your dial caliper, it would read out as .75 inches on one side and 3.5 inches on the other side. This type of measurement lets you take quick measurements between different objects without having to switch from one tool to another.

There are currently dozens of manufacturers that produce consumer-grade dial calipers. While they may be very similar in function and appearance, some slight differences exist between models. For example, the Anytime Tools Dial Caliper is a tool that has a duel reading scale and 0.01mm/0.0005″ / 0.1mm/0.005″ resolution. It has stainless steel robust body. That makes it a very popular tool for professional and personal use.

Best Dial Caliper Buying Guide

measure with dial caliper

A dial caliper is one of those instruments that may come in very handy from time to time when doing small fabrication or repair work around your house or shop. It can accurately measure inside or outside dimensions, depth, etc. It is also used in the industry for accurate machining and inspection work. First of all, do you make sure that it is helpful for you?

Which Metal is Used?

These instruments are typically made from cast metal parts with hardened steel jaws for durability purposes – they are not intended to take high impacts or be dropped. They are best used as a stationary tool. You should not expect them to provide accurate results if they are taken from their original “home” and forced into awkward positions such as trying to measure small objects with your hand or upside down on the floor etc.

How the Jaw Moves?

When making a purchase decision, be sure that the jaw width is adequate for what you intend on measuring and that it is large enough so that it does not impede your view of the dial graduations when taking measurements. Also, some models have adjustable jaws, which can come in convenient depending on what you need to measure.


If there is one thing you will notice immediately after using these instruments, they are sensitive. Dial calipers will tell you the slightest of contact and even air movement if you apply enough pressure to them. That can be a problem when taking measurements on delicate objects such as thin sheet metal, plastics, etc., so take care and use caution with these instruments.


The best dial calipers will allow you to make very tiny adjustments to the reading. That can become important when measuring an object that has tight or small tolerances, such as screws or threaded holes, etc. 

Plastic or Metal Dial Caliper?

One notable difference is the material used to make the device. Dial calipers can be manufactured using plastic or metal. Plastic dial calipers are lighter than metal dial calipers. However, they have a lower maximum load capacity.

The best way to determine which type will best suit your needs is by identifying what you plan on measuring with it often? For example, if you only plan to measure small objects, then a plastic dial caliper would be best. If you need something capable of taking more extensive measurements, then a metal dial caliper is best.

How to Read A Dial Caliper? 

Using these tools takes some practice but typically isn’t too tricky once you’ve gotten the hang of it. The following steps will help you get started:

Place Your Object

Place your object on a flat, stable surface that won’t shift or move while being measured. ·   

Make sure to place the object so that whichever side is closest to you is flush with whatever surface you measure up against (e.g., the edge of a table). · If you are using a dial caliper or digital caliper, make sure to use an extension rod if necessary so that it doesn’t have contact with any other objects while being used.

Open the Jaw

Open one jaw on your tool all the way and rest it next to where one of your surfaces will be touching the table’s edge. If using a digital caliper, make sure the jaws are open all the way by using the release button to retract them. · Rest your object up against whichever jaw is opened and then use your fingers to slide the other jaw over until it contacts your object. 

Take Measurement of One Side

If you don’t feel like measuring both sides of an object, you can always measure just one side (otherwise known as taking an inside measurement). Just take note of which side you’re resting against before making any measurements; once finished, flip it around and rest it up against that surface instead.

Taking Outside Measurement

Taking outside measurements follows a similar principle. Just make sure to take one outside measurement, flip your object around where it needs to be, and take the other side’s measurement.

Taking Measurements of Both Side

To get an inside or outside diameter reading, hold down the button on top of your caliper while you slide its jaws. So that they fit directly over the widest part of your object, keep holding this button in place while you read off measurements from the dial counter-clockwise, starting with 0 at the furthest point away from you.

How Does A Dial Caliper Work?

A dial caliper is a tool used to measure the exact thicknesses of an object. It works by taking measurements on the outside of the thing, which is displayed in a digital reader above the device’s handle.

Calipers work best with flat objects or cylindrical objects but can also be used for other objects as long as they are measurable using one of these techniques. The best way to use them is 

  1. Place the object flush against an edge on one side of what you want to measure.
  2. Then track across towards another edge on the opposite side. 
  3. Once there, you unlock them to be placed around the object you’re measuring. 
  4. After this point, you turn on the instrument before reading off numbers from its display.

Calibrating the dial caliper is simple and can be done using a screwdriver. That ensures it remains accurate for future use after calibrations are made.

How it Works

A dial caliper uses two legs that can be adjusted and locked into position to form an enclosed assembly around an object. One leg has a pointed probe at its tip and rests against the inside edge of one surface being measured; meanwhile, the other leg has a fixed search and rests against the outside edge of the same surface. The open space between these two legs is measured to get an accurate distance or length.

The components that measure the gap are located on the slide assembly. When you push this back and forth, it slides one leg closer to another until it finds an object to rest up against so it can determine how far apart they are. Then, you get your reading by measuring how much movement there was in this slide assembly!


Q. What Are Dial Calipers Typically Used for?

Ans. A dial caliper is a tool used to measure an object’s thickness, width, or depth. It has a movable arm with a pointer and a dial that reads the distance the arm has moved. This type of caliper is also called a Vernier caliper.

Q. Are Dial Calipers More Accurate Than Digital?

Ans. Digital calipers are similar to dial calipers, but they have digital readouts instead of dials. Digital calipers can be more accurate than dial calipers because they have an electronic readout that is less affected by external factors.

While digital calipers are accurate, they are also limited. They have a fixed scale, and they can only measure linear distances.

Dial calipers have a variable scale and can measure both linear and angular distances. That means that they are more accurate and versatile than digital calipers.

Q. What Are the Steps to Using a Dial Caliper?

Ans. There are many steps to measuring and using a dial caliper. These points will show you how to use a dial caliper in different situations and the best practices for each one.

  • Select the length of the measurement
  • Place the point of the dial at zero
  • Place the other point of the dial at the desired measurement
  • Move pointer up or down until it clicks into place
  • Read measurement from pointer
  • Repeat steps 1-5 for other measurements

Q. What Kind of Calipers Are Most Accurate?

Ans. The accuracy of a caliper is determined by the number of teeth on each side of the jaw. This tool is mainly used to measure the thickness or width, such as metal, wood, or plastic. It’s also used to measure the depth and distance between two surfaces.

The most accurate calipers have more than ten teeth on each side. Remember, there is no single type of caliper that is most accurate. It depends on the specific application and the user’s preferences.

Q. How Do You Zero a Dial Indicator?

Ans. Zeroing a dial indicator is a process that can be confusing to learn. It is also difficult to remember the steps and the order of operations required.

To zero a dial indicator, you need to make sure the pointer is in the center of the scale. You then move the pointer around until it reaches zero on both sides.

The last step is to move the pointer back up to the center and read off your measurement.

Q. Where Are Dial Gauges Used?

Ans. A dial gauge is a tool that measures pressure and torque using an internal rotating disk with calibrated markings. Dial gauges are widely used in the automotive industry for tire inflation, checking engine oil levels, or measuring the torque applied to an object being turned by hand or by a machine tool. 


There is not an ultimate answer to this question, as the best dial caliper for you will depend on your choice, specific needs, and preferences. However, some of the most popular and highly rated models on the market include the Anytime Tools dial Caliper, the Kynup digital Caliper, and the iGaging dial Caliper.

You’ll want to consider various factors when purchasing a dial caliper, such as the size of the caliper, the precision of the measurements, and the materials from which it is made. Make sure to do your inquiry before purchasing to ensure you find the model that is best suited to your needs.
