Amongst the types of calipers, the dial caliper stands on the mid-choice. Compared to the vernier caliper, dial caliper offers easier to read, faster measurement, and less error. Meanwhile, even though it’s not as fast as the digital caliper, it’s not dependable on the battery; no worry suddenly turning off that forces you to buy the battery right at that time.
When you are trying to get the best dial caliper, there are some considerations such as the accuracy, material, rigidity construction, reading unit, smoothness, thumb screw, etc. You should also consider the right dial caliper for certain jobs such as machinist and woodworking.
Picking the best one can be time-consuming as there are so many choices of dial calipers and they spread amongst the brands such as Brown & Sharpe, Starrett, Mitutoyo, Anytime Tools, iGaging, etc.
To help you reroute the way of finding your best dial caliper, in this coverage, the following options are hopefully able to get you faster and we believe they are worth recommending. They have passed some selection and comparison.

What is Dial Caliper?
A dial caliper is a mechanical tool. It’s one of the types of caliper that works mechanically employing the rack and gear. The mechanism will turn the hand at the dial clockwise. The hand then points to a particular mark as the measurement reading.
Whether it’s displayed in inch or mm, you can choose from which one you are familiar with. This could be a matter of the country you are living in. Fractional graduation is also available and suitable for woodworking as they usually work with that reading. While decimal is widely spread over a number of jobs.
Commonly, a typical dial caliper currently provides 0.001″ / 0.02mm resolution. People normally rely on a dial caliper to do a fast measurement with great accuracy. Besides, the other advantages are:
- No battery issues so you will never figure out the power
- The stainless steel construction is powerful to fight rusting
- No electronics issues so you can spot if there is trouble with reading
- Quite easy to repair than most digital calipers
- You could do inside, outside, step, and depth measurement in a single tool
Things to Figure Buying Dial Caliper
1. Range of Measurement
When buying a dial caliper, it’s important to consider the measuring range you are appropriate with. There are several ranges you can choose: 4″, 6″, 8″, and 12″. The 40″ is actually available on the market. But it depends on the company whether they provide those different sizes or not.
Considering the range also means considering the price. The more the range, the more expensive it is. In addition to the consideration of the range, it’s worth noting that the longer the caliper, the less accurate it is.
If you don’t have any idea of which range to pick, pick the 6-inch one as this range should cover many tasks using a caliper.
Resolution is important for a precision measuring tool. For a dial caliper, the most common is 0.001″. If your dial caliper doesn’t give this resolution, don’t buy it. You’d rather buy a vernier caliper. However, if you need higher resolution, it seems that no dial calipers higher than 0.001″ resolution currently. You may need a micrometer. It’s a far better resolution than caliper.
Accuracy shows the degree of how identical the measurement results to the standard. This standard unites the definition of 1″ (for instance) for all places in the world. It will be a long explained guide to tell you about accuracy. Accuracy covers many things such as repeatability, uncertainty, traceability, etc.
Simply, an accuracy of a dial caliper has to be at least the same as its resolution. For example, if the resolution is 0.001″, then the accuracy should be ±0.001″. Accuracy is expressed in the “±” sign and number. Herewith, if the reading shows 1.002″, the true reading ranges from 1.001″ to 1.003″.
You may expect your caliper has higher accuracy than its resolution, but so far we don’t find it yet.
Since the majority of dial calipers come with 0.001″ resolution, its accuracy needs to be ±0.001″ at least. Sometimes, a certain product doesn’t come with a clear description of its accuracy. In this case, you should avoid it for precision measurement. You could keep using it but further calibration using a block gauge is importantly needed.
4. Material Construction
You need to choose a suitable material for all of the dial caliper parts. These materials are expected able to give corrosion and abrasion resistance. Stainless steel or hardened stainless steel is at least the main material for its critical parts. You should avoid plastic unless for less unimportant parts.
5. Carbide-tipped Jaws
Another extra enforcement is required for the jaws when it is frequently used for heavy jobs. Like carbide-tipped anvil in a micrometer, carbide-tipped jaws are great to coat the jaws for more durability. It is more resistant to wear than stainless steel. The calipers with carbide can be expensive but it offers a great return; lasts longer. Not only does it provide durability, but also the accuracy improves. Great to use in a machine shop or other heavy-duty jobs.
6. Clear Display
A clear dial display can help you get a quick reading. Some people may use the dial caliper in a less light site. In this case, pick the color that reflects the light. High-quality crystal also helps get a clear reading. However, this fancy crystal may cost more. Make sure the numbers’ size is not too small, pretty large to see from a reasonable distance.
7. Thumb Wheel
For a single-handed user, the thumb knob is highly useful to slide the dial back and forth. It helps give the right pressure to the object being measured. Many people consider this feature important so do we. It gives convenient and proper use. Most of the dial calipers come with this feature.
8. Smooth Slide
Feel a great measuring experience with dial calipers that slide smoothly. A nice smooth sliding dial caliper shows a high-quality product. However, the smoother the dial caliper, the more expensive it is. So, if you prefer this advantage, you need more budget.
9. Knife Edge Jaws
It has the advantage to increase accuracy. Some inaccuracy issues come from the flatness and parallelism of the jaws. The knife-edge jaws reduce the surface area that touches the workpiece. This can result in a more reliable measurement.
Some brands have their dial caliper spare parts available for sale. In case your dial caliper breaks apart, you can replace the broken parts such as its crystal. Perhaps you don’t want to turn to the other calipers. You don’t need to buy a new one and can save some bucks. Further, you can hand it down to your son.
The case is important to secure the dial caliper when it’s not in use. Sometimes, it can crash with other tools. Herewith, the chase shields it. Storing it in a chase also means protecting it from water. If you can store it in a good humidity condition, then it’s way better.
