Digital calipers are a useful tool when you need to take accurate measurements. There’s no need to work out unit conversions when you’re on the job—the handy digital calipers do it for you. The right pair can save you a lot of time and prevent costly mistakes.
Finding a reliable pair of calipers is easier said than done, though. There are many models out there, and these tools are not created equally. In this post, we’ll take a look at the ten best digital calipers currently on the market so that you can make a more informed purchasing decision.
Features to consider in Good Digital Calipers
The most important considerations when buying a set of calipers is the accuracy of the product, the types of measurements it can perform, and the reputation of the brand in a competitive industry.
Accuracy
The degree of accuracy you require depends on the projects you undertake. If you’re a DIY woodworker and need to build a cabinet, you have some tolerance for error. Not much, but a fraction of a millimeter here or there is not going to cause significant problems.
For the professional, though, it’s more complex. If you’re machining parts that must fit precisely, you need professional-grade calipers that are highly accurate. You can read more about the ASME and international standards as the guidelines apply to accuracy here.
Type of Measurements
The most versatile calipers take four sets of measurements:
- Inner Measurements – The caliper arms are placed inside the object to be measured. You then open the arms until you’ve determined the measurements. The outside of the arms is the point of contact.
- Outer Measurements – The caliper arms are opened first and placed on either side of the object at the widest point. You draw the arms together on either side to obtain the measurements. The inside of the arms is the point of contact.
- Depth – If you need to find out how deep a hole is, or how thick a plank is, depth measurements are vital. Here the caliper is turned around so that you can place the pointed end of the arm into the cavity.
- Steps – You place the upper end of the caliper against the first step. The jaws are then opened until you reach the second step for an accurate measurement.
Dealing with a Reputable Brand
Finally, a reputable brand is essential. There are plenty of cheap models on the market, but the problem is that these products will usually only work a few times before becoming inaccurate.
Dealing with a reputable company is a wiser investment, even if it means paying slightly more.

Guide to Buying the Best Digital Calipers
Now that you have seen our top ten choices, here is what you need to consider before buying your next set of digital calipers. We’ve included some useful tips on how you can get the most out of your new set.
Where Digital Calipers are Most Useful
You’ll usually use a digital caliper when highly accurate measurements are necessary. Possible applications are metalwork, carpentry, mechanical engineering, or machining. The point is that this tool is essential when pinpoint accuracy is required.
Caring for Your Digital Caliper
If you lay a digital and dial caliper side by side, you’ll notice that the former is more accurate and easier to use. The payoff for this accuracy is that you need to handle your digital set with a lot more care than a traditional model.
You can safely toss your dial caliper into your toolbox, and it will stand up to a fair amount of rough handling. If it gets dusty or dirty, it’s no big deal. Wipe it down and carry on.
The digital caliper is more sensitive to handling and dirt, however. It’s essential to store the tool separately from your other equipment, preferably in a sturdy case. It must have a tightly sealed mechanism to prevent dirt jamming up the interior.
You don’t want to subject your digital calipers to unnecessary knocks and bumps, either. Rough handling throws off the digital calibration, leaving the calipers useless.
There are many brands out there, and you’ll find them in standard or metric units. Some make it easy to convert readings from fractions to millimeters to inches, and so on.
If you have a more advanced model, you’ll be able to plug it into your PC or phone using a USB cable. It allows a quick and effortless transfer of the measurements.
Features That the Best Digital Calipers Should Have
Depth Gauge
The gauge allows you to measure yet another element—how deep a hole is and how thick the material is that you’re handling.
Locking Screw
Not critical to the functioning of the calipers, this is still a useful feature. The locking screw holds the jaws of the caliper in position. You take your measurements, lock the position, and then move the calipers without fear of the jaws slipping.
A locking screw makes it much easier to take accurate measurements in a hurry.
Step Gauge
The step gauge makes it possible to measure from the edge of your material to a particular point. It is useful if you need to drill a hole into a specific spot on your project.
ABS Button
The ABS button allows you to zero the measurements as necessary.
Outer Jaws
The jaws make it possible to measure the interior of an object. For example, if you need to measure the diameter of a pipe, place the caliper jaws inside the tube and take the measurements using the outer jaws.
Inner Jaws
The inner jaws measure the outer edges of your project. In the above example, you’d place the whole pipe between the inner jaws of the calipers. It’s best to slide these along smoothly as jerking the jaws can break them.
Zero Button
The Zero Button replaces the ABS button in some models. It often doubles as the ‘On’ switch, as well.
MM/ In Button
It merely converts millimeters to inches. Better models also convert millimeters to fractions.
Auto Shut-off
Technically, an auto shut-off is a “nice to have” feature. It’s not going to affect how your calipers perform, but it is useful in saving battery power. When you’re busy in your workshop, it’s easy to forget to switch the calipers off.
Without the auto shut-off feature, the calipers stay on. Leaving the LCD display on is a significant drain on the battery power, so the auto-shutoff feature shuts off the calipers after a period of inactivity.
Stainless Steel Body
If you’re going to be using your calipers regularly, it makes sense to invest in a stainless-steel pair. It lasts longer and functions more smoothly. The sleeker the surface, the easier it is to slide the jaws and obtain an accurate reading.
A Big LCD Screen
Like a TV, the smaller the screen, the closer you have to be to see it. Find a set with a large LCD screen to make it easy to read the numbers.
Smooth Operation
Reliable calipers will slide quickly and smoothly. If your set is always sticking, you won’t want to use it.
Length
In the reviews above, we stuck to six-inch calipers. There are plenty of other lengths, though. Choose the appropriate range for the projects you undertake regularly.
IP54 Protection
IP54 protection keeps water, dust, dirt, and insects out of your calipers. Expect to pay more for these models. The extra expense is worth it if you’re working in a dirty environment.
The Most Important Feature to Look for in Digital Calipers
We’re giving accuracy a section of its own because it’s that important. If you’re working in a high precision field, it’s better to pay slightly more for a highly accurate set of calipers to avoid mistakes.
In this video, you’ll see a live comparison of several different generic brands versus the Mitutoyo calipers. It’s interesting that the less expensive brands were relatively accurate, but not exact. Check out the video at 8 minutes 21 seconds, and you’ll see what we mean.
Other Things to Consider When Choosing Your New Set of Digital Calipers
Durability
A decent set of calipers lasts for many years. When you’re considering a new set, check reviews on durability. It’s normal for one or two reviews to be negative.
Some users are rough with their sets, which are more likely to break, but if an overwhelming number of the reviews are negative, find another model.
Price
A good set of Mitutoyo calipers will cost you $100 or more. Is that worth it? It depends on why you need the calipers.
As in the video above, you can find far cheaper models that are still relatively accurate. Some were only a millimeter out. If you’re using it in a professional capacity, though, it’s worth going for the more expensive models. It will last longer, even with daily use. If you’re a home enthusiast and only use them occasionally, the cheaper versions should be fine.
Calibration Certificate
You can opt to purchase a calibration certificate with your new Mitutoyo calipers. Is it worth it? If this is your profession, it could be, but if not, stick to a reputable company, and don’t worry about the certificate.
Warranty
We recommend a brand that carries a decent warranty. The industry standard for digital calipers is one year.
How to Use Digital Calipers
Finally, let’s discuss how best to use your digital calipers. This video below will give you a great introduction on how to get started.
Digital calipers are simple to use. The main consideration is to always start from zero.
Get into the habit of closing the jaws of the caliper when you’ve finished taking measurements. When you’re ready to take the next measurement, the calipers will already be in the default position.
Step 1
Make sure the caliper arms are in the closed position and turn the device on.
Step 2
Zero the readings on the device. You will usually do this by pressing the ABS button, or the Zero button.
Step 3
Position the calipers correctly. The right position is possibly the most challenging part of the process. You also need to use the right part of the caliper when you measure something.
Here are some quick tips:
- Set the calipers on the broadest part of what you’re measuring.
- If you want to measure the inside of an object, use the outer jaws.
- When you want to measure the outside of an object, use the inner jaws.
- If you need to measure the depth of an object, use the depth gauge on the top of the calipers.
- If you want to measure steps, use the step gauge.
How to Get More Accurate Readings From Your Digital Calipers
Digital calipers are sensitive pieces of equipment. For more accurate readings, you should always wipe down the arms before use. Even the natural oils from your fingers can throw off the accuracy of the reading.
It’s also better to try and wipe down the object that you want to measure too. Dust and dirt also lead to inaccurate readings.
Finally, if your calipers come in a case, use it for storage in a bag that keeps the dust and dirt off. IP54-rated calipers allow you to be less careful, as these are resistant to dust, water, and oils. If you want to improve the accuracy and shelf-life of your set, store it properly after every use.
Remember, if your set doesn’t come with an auto shut-off switch, remember to switch it off when you’re finished.
Final Thoughts
Every caliper on this list will give you the precise measurements you need to get your home project off the ground. Many are also suitable for professional use in the workplace. We hope our guide has given you some excellent information on how to make the most out of your digital calipers. Take a look through our list and decide which one is best for your project in the confidence that you’ll get what you need.
