To determine the best digital caliper we looked at the following options: materials, accuracy, caliper length, battery life, and water resistance. For the best experience, you should prioritize a stainless steel design that is more durable. Most people will find that a caliper that measures zero to six inches should be more than sufficient. And they should focus on options that are at least accurate to within 0.001 inches. Additional features such as auto shut off and an IP54 water resistance rating also helps to preserve the life and quality of your digital caliper.

After considering all of the above, we nominated the Rexbeti 6-Inch Digital Caliper as our Top Pick. This digital caliper is constructed from stainless steel and features an IP54 rating. It’s accurate to within 0.001 inches, and can also provide measurements in inches, millimeters, and fractions. Keep reading to learn more about the rest of our top picks. You may also compare this equipment with other top-quality tools in the market.

This includes a zero to six-inch measuring capability, IP54 water resistance, measurements that can be displayed in inches, millimeters, and even fractions, as well as a large LCD screen. As is standard, you can measure internal, external, depth, and step measurements. And as with all of the other digital calipers in our guide, this one is also composed of a stainless steel body. The best torque wrench is another great tool when you need precision.

How We Decided

Digital calipers are a critical tool for a range of professions such as machinists or even woodworkers. To help narrow down our recommendations for the best digital calipers, we focused on the following features — materials, accuracy, caliper length, battery life, and water resistance.

As you go through our recommendations, you’ll note that many of them have similar qualifications. And where this occurred, we made a note of it. Specifically, all of our digital caliper recommendations are designed to measure between zero to six inches and are made from stainless steel. This is ideal for the average user, and stainless steel construction will be more durable. And all of our recommendations also come standard with a storage case.

Likewise, all of our calipers can measure in both metric and imperial lengths. And more importantly, they can all switch between inches, millimeters, and fractions. Likewise, they all feature a large LCD screen for easy reading, and the ability to gauge internal, external, depth, and step measurements.

In terms of accuracy, our Best Quality offered the highest accuracy to within 0.005 inches or 1/64 whereas the remainder are accurate to within 0.001 inches or 1/32. And water resistance is also a feature that isn’t always standard. While most of our recommendations offer an IP54 rating, our Honorable Mention and Best Budget do not. However, we did note that most of our recommendations came with an additional battery. But to preserve that battery, focus on our Best Budget and Best Quality recommendations since both of these models offer an auto shut off feature.

Digital Caliper Buying Guide


The Most Important Factors to Consider

  1. Materials
    Digital calipers can be made from a range of materials such as stainless steel, plastic, composite material, and carbon fiber. Look for a digital caliper with sturdy and durable inside outside jaws. Although stainless steel tends to be the most expensive, it’s also the most durable option. And that means that even with a higher upfront cost, you’ll save money in the long term.
  2. Accuracy
    The main point of using a digital caliper is to measure lengths. So you’ll need to consider whether your caliper is properly calibrated, and how accurate the measurements will be. For precise measurements, it needs to have an increment of 0.01mm or 0.0005”. A poorly calibrated caliper will give you inaccurate measurements. Look for digital calipers that have already been calibrated and can be used straight out of the box. Also, look for one that has a high-quality locking screw because the measuring jaws need to be well locked for accurate measurements.
  3. Measurements
    Most digital calipers provide readings in imperial and metric readings. This is ideal so you can easily convert between the two systems rather than having to do the calculations yourself. But not all of them display measurements to the same decimal point. Depending on the objects being measured, this can be a deal-breaker if you need to measure to the 100th of a point, and your caliper can only provide accuracy within a 10th of a point.
  4. Ease of Use
    By default, digital calipers are significantly easier to use than other types of calipers because of their digital readouts via the LCD screen. But even so, you still want a tool that’s easy for you to handle and to make adjustments. Look for options such as a sensitive thumbwheel and smooth jaw movement to make your projects easier to complete.
  5. Caliper Length
    Calipers can come in a range of lengths, but most people should be fine with a digital caliper that has a measuring range  between four to 12 inches. But for the right tool for the job, always consider the length of what you’ll be measuring before you buy a digital caliper.
  6. Battery Life
    Digital calipers are typically battery-powered. Consider models that offer an automatic shut off feature. This will help to preserve battery life between uses.
  7. Water Resistance
    Although it’s not a requirement, a digital caliper with a water resistance rating can ensure that your tool lasts longer and can withstand exposure to water. If this is a feature that’s important to you, look for an IP54 or higher rating.

Digital Caliper FAQs

How accurate are digital calipers?

There’s only one type of caliper which is more accurate than a digital model, the vernier caliper. Digital calipers are known to provide an accuracy of 0.001 inches (0.02 millimeters) along with a resolution of 0.0005 inches (0.01 millimeters).

What does a digital caliper do?

Digital calipers are instruments used to measure internal and external distances with extreme accuracy. What makes them especially useful is the fact that you can often easily convert between imperial and metric readings.

Are digital calipers more accurate than dial calipers?

Yes, digital calipers provide better accuracy than dial calipers. However, this will also depend on how well-calibrated your caliper is.
