How to Calculate Distance Using a Laser Distance Measurer

Take aim with a laser distance measurer to find accurate distances in less time than a metal tape measure. Rather than fighting with a long metal tape, a laser measurer sends a pulse to a distant object, times the return and translates the results into a measurement. Find out how to use one of these convenient devices today.

Choose a Solid Target

A laser measurer won’t produce accurate results if you’re pointing it at a porous, reflective or water-covered object. Anything that can affect the beam or create an inconsistent target may create inaccurate results. Review your laser device to find the recommended surfaces and surfaces that may cause errors in the measuring process.

Once you point the laser at a solid target, use the device-specific instructions for use. Some require you to choose a straight distance measurement feature, while others only include one feature and simply require you to press a button to receive a reading.

Use the Right Laser Device

How to Calculate Distance Using a Laser Distance Measurer

Not every device allows you to measure long distances accurately. Consider your project to determine the type of laser device you need. Some devices allow you to make complex calculations, check items for level or project a level line on the wall. Others are only capable of measuring a straight line for a short distance.

Be sure you know the margin of error and maximum distance of your device. While incredibly accurate, most laser devices have a known margin of error. They also have a known maximum distance, so you won’t be able to take accurate measurements over a certain distance, typically around 650 feet.

Calculate Indirect Measurements

If your device supports indirect measuring, you can instantly calculate an unknown distance using the Pythagorean Theorem. Start by selecting the right mode on your measuring device. Measure the two distances you can. Your device should immediately calculate the distance of the third leg of the triangle.

You can still calculate a missing triangle dimension even if you don’t have this feature. Simply measure the first and second distance, then use the Pythagorean Theorem: a² + b² = c². This allows you to find unknown distances in your commercial or DIY construction project.

Frequently Asked Questions

How Far Can a Laser Measure Work?

The maximum distance depends on how accurate you need your laser distance measurer to be. Many can be used to measure distances up to 650 feet. However, the result has a margin of error, typically less than an inch. Shorter measurements are typically more precise, making a laser measurer a great tape measure alternative.

How Do You Measure Short Distances With a Laser?

How to Calculate Distance Using a Laser Distance Measurer

A laser distance meter can be used to measure a wide range of distances. Because of the slight margin of error, and the size of the unit itself, there is a minimum distance to a laser device. Consider using a micrometer or other measuring device to measure particularly small distances.

How Accurate Is a Laser Distance Measurer?

You can typically receive a measurement that’s accurate within 1/8 or 1/16 of an inch. The accuracy depends on the object you’re choosing to measure, the distance of the object and the quality of the laser measurer you’re using. For most applications, a laser measurer has an acceptable margin of error.

What Is the Best Distance Measurer?

Consider your typical projects before choosing the best laser distance measurer. If you only use one occasionally around your home, a compact and affordable one is best. Consider the accuracy, durability, maximum length and optional features to find the best for commercial use. Shop for laser devices online for head-to-head comparisons.

Are Laser Levels and Distance Measurers the Same?

Laser devices offer convenient ways to measure distances and check if objects are level. These are two distinct features, but some laser devices incorporate both in a two-in-one device. Check the features of your chosen distance measurer to see if you need to purchase a separate laser level or if you have an all-in-one device.
