What is a digital caliper?


A digital caliper is a precision measuring tool used to take precise and accurate measurements of small objects with a high degree of accuracy. It is used mainly in technical industries such as manufacturing and mechanical engineering for measuring the dimensions of objects such as diameter, thickness, depth, and length. It has a digital screen display that shows the measurements, making it easy to read and take the appropriate measurements. Digital calipers can come in various sizes, but most are handheld and commonly range from six to eight inches in length. They are a reliable and widely used tool in many industries where precise measurements are of utmost importance.



Step 1: Choose the Right Digital Caliper


Before you start measuring your dice, you need to make sure that you have the right tool. A digital caliper is the best tool for the job, as it offers greater precision and accuracy than other measuring tools. You should choose a digital caliper with a measuring range of at least 6 inches and an accuracy of 0.001 inches. The digital caliper used in his post was purchased on Amazon for around $8. The caliper came with 2 extra batteries. Don't let the cheap price fool you, this versatile tool can do the job with ease!


Step 2: Set the Digital Caliper

Now that you have the right tool, it's time to set it up. Turn on the digital caliper and set it to the zero point. Close the jaws of the caliper and make sure that they are perfectly aligned. You can calibrate the caliper by sliding it back and forth while closed to ensure that it is reading zero correctly.


Step 3: Measure the Dice

With the digital caliper set up, it's time to start measuring your dice. Place the die you want to measure into the jaws of the caliper, being careful not to touch the edges of the die. Hold the die steady in place with one hand, and use your other hand to operate the caliper. Gently close the jaws around the die, being careful not to force it.

 So how do you measure the dice? 

Once the jaws of the caliper are closed around the dice, the digital display should show the measurement of the die. Make sure to read both the internal and external dimensions of the die to ensure that you're getting accurate measurements. Note down the measurements for future reference.

Step 4: Compare the Measurements


Now that you have the measurements of your dice, you can compare them to the standard measurements for the type of die you're using. For example, the standard size for a D20 die is 16mm, and if your measurements are close to this, you can be assured that the die is the correct size. If your measurements are off significantly, you may need to replace the die or adjust your gameplay accordingly.

Using a digital caliper is a simple and effective way to measure the size of your dice. By following these steps, you can obtain accurate measurements and ensure that you're using the correct size dice for your tabletop games.

But what if you don’t have a digital caliper? Are their other ways to measure dice? Sure! 

If you don't have access to a digital caliper, here are some alternatives you can use:

  1. Vernier caliper: This is a more traditional type of caliper that uses a sliding scale to measure external, internal and depth dimensions.

  1. Dial caliper: This type of caliper is similar to the vernier caliper but uses a dial for more precise readings.

  1. Measuring tape: For longer measurements, you can use a measuring tape or ruler to get approximate dimensions.

  1. Micrometer: A micrometer is a more precise tool that is used for measuring smaller objects or precise measurements.

  1. Visual reference: In some cases, you can use a visual reference, such as a coin or dollar bill, to estimate the size of an object.
