When it comes to woodworking, or any kind of construction, the golden rule is "measure twice, cut once." The fool's rule is the inverse, "measure once, cut twice." When you sit down to do your measurement, you need it to be as precise as possible, because the slightest mistake can cost you. The usual device, the tape measure, is great for measuring large numbers. However, to measure the tiniest of numbers accurately, you need a caliper. Digital calipers are the best as they do most of the complex number crunching for you.

Because digital calipers are designed to measure distances as little as one-thousandth of an inch, they’re typically small. The standard digital caliper can only take measurements as large as 6 inches. There are larger sizes available, though, if you require them. Usually, these come in increments of 2 inches with few, if any, coming in larger sizes than 12 inches. You can also find smaller ones, though it's rare or impossible to find one smaller than 4 inches.

The two main measurement systems in the world are imperial, used by the United States, and metric used by essentially everyone else. Lower-cost digital calipers typically use one or the other system, so double-check that you’re ordering the correct type before purchasing. Higher-end ones can swap between both systems at the touch of a button, which is a godsend if your work requires both. However, if you only need one type then go ahead and save your money.

Most digital calipers are made of either plastic or stainless steel:

Some digital calipers offer extra bonuses that, while small, can make the difference when deciding which to purchase:

Digital calipers can be found for $25 or less, though these are only suitable for the occasional basic project. Better ones with more features can cost up to $100. The best calipers that pack in high-end features for serious woodworkers only start around $100.
