How To Choose The Best Laser Tape Measure?

A laser tape measure (also called laser distance measurer) is a machine that uses a laser to measure distances. For the professional contractor or serious home improvement hobbyist, this tool is a huge improvement over a traditional tape measure.

The laser technology provides you an extremely accurate distance instantly, thus saving you time and improving the quality of your work. It also allows you take any measurement you need by yourself, while traditional tape measures require two people to keep the measure level when used over large distances.

How Does A Laser Tape Measure Work?

A laser tape measure uses a laser beam to determine the distance to a certain point. The most common form of laser tape measure sends a laser pulse toward the object and measures how long the pulse takes to bounce off the target and return to the machine.

This measurement process is often called the “optical measurement process” and can be displayed in multiple units of measure.

Who Needs A Laser Tape Measure?

A laser tape measure would be useful to anyone working on a construction or remodeling project, both professional and amateur, such as contractors, electricians, carpentry, masonry, interior designers, home owners etc. Quickly find the area of a wall so you know how much paint to buy, or the correct angle at which to construct a roof.

It would also be a great tool for real estate appraisers, as they could measure a property’s dimensions with a couple clicks of a button instead of using huge tape wheel or other manual measuring tools.

How To Choose The Best Laser Tape Measure?

If you often have to complete these tasks with conventional tape measures or find yourself constantly completing these calculations by hand, then a laser tape measure may make your work more efficient and your life easier.

In order to choose the right model for your project’s need, here are several factors to consider before making decision.

  1. Measuring Range
  2. Accuracy
  3. Measurement Units
  4. Functions
  5. Display
  6. Memory
  7. Battery Life

#1 – Measuring Range

The range you need depends on how you will use your laser tape measure.

  • Amateurs working on small home improvement projects don’t need ranges past 100 feet, while the average professional contractor or real estate appraiser should be good with a range of 100 feet to 300 feet.
  • Those working on huge job sites, like industrial construction, road construction or surveyors dealing with large tracts of land need models with 300+ feet of range.

However, there are more factors that determine range than simply how powerful the machine is. For example, the maximum range listed on any model will refer to what is possible when the laser is used with a reflective target, which is sold as cheap accessories by the manufacturers.

Without a reflective target, the range will then depend on the following factors:

  • The amount of light (the darker the better)
  • The surface the laser is being pointed at (smooth textures and lighter colors tend to work better)
  • How clean the area covering the laser is (it’s best to treat your laser like you would with an expensive camera lens)

You will also increase your range by holding the laser measure as steady as possible when aiming it at the target.

#2 – Accuracy

The cheapest models are often only accurate to 1/4 of an inch, which is fine for general area calculations, like determining how much of a wall needs to be painted or how long a fence needs to be.

For most construction or landscaping work, it is a good idea to have accuracy to 1/16 of an inch, while more technically demanding tasks demand accuracy to 1/32 of an inch.

#3 – Measurement Units

Virtually all models come equipped with the ability to measure in some popular measurement units (inches, feet, decimal feet, metric units…) and many laser measure can toggle between units easily.

However depending on your preferences, it may make more sense to consider carefully and buy a version that displays the units you want to avoid potential confusion.

#4 – Laser Measure Functions & When To Use

The fact is that you may not need a laser distance measure with all complicated functions if you only work on small home remodeling projects. On the contrary, a professional working at large construction site on a daily basis may require a model with more high-end functions.

So understand various functions of a laser measure will help you determine which functions can help to complete your job.

Read more about the various functions below to choose the best laser tape measures:

FunctionsDescription/Use
Length Measurement
This function is used to measure the distance from one point to another. For example, the width of a door or window, or the length of a wall.
Area Measurement
Area function is used to find the total surface area that exists between that length and width. For example, the amount of wall that needs to be painted, how many tiles you need for a floor, the size of the marble slab needed for a countertop.
Volume Measurement
Volume is length times width times height. For example, you need to determine the volume of a swimming pool to know how much water is needed to fill it, or the volume of a garden bed to know how much soil you need to buy.
Addition/SubtractionModels with addition and subtraction keys allow you to add and subtract measurements to find a certain value
Continuous MeasurementThis feature lets you measure multiple distances and add them together automatically.
Single Indirect MeasurementThis function is useful when you need to determine the height or width of something indirectly. For example, when measuring the height of a wall without using a ladder, you can measure the two other sides that form a triangle with the side you want to know, and then use this function to calculate the third side.
Double Indirect MeasurementDouble indirect measuring is useful when you only need to know parts of a total height. For example, the height of a window out of the total height of the wall.
Combined Indirect MeasurementThis feature lets you measure multiple distances and add them together automatically.

Trapezoid MeasurementWhen you encounter trapezoids that need measuring, such as sloped ceilings, roof slopes or frontage areas, the laser tape measure with trapezoid measurement function can help you solve the calculations quickly.
Minimum MeasurementThe minimum function is used to find “minimum values”- for example, the shortest perpendicular distance between two walls.
Maximum MeasurementThe maximum function is used to find “maximum values”- for example, how far away two points at a diagonal distance are from each other.
Multi-Surface Area MeasurementThis function is useful to calculate the total area of many different surfaces with a common length or height, such as different walls of a room or different garden beds.

Angle MeasurementLaser tape measures are especially useful for measuring angles. Simply point it where you need and let the machine do the calculating for you.
Timer FunctionThe timer function lets you know when your laser measure has completed its reading, and thus able to be moved. It is essential the laser remain steady to ensure an accurate reading.

#5 – Back-lit Display Or Not?

A back-lit display makes the screen easier to see in bright glare than conventional screens, while also being easy to see in low light. Not all models come with the feature, so if you find yourself using your laser often in these situations then it’s worth having a laser tape measure with back-lit display.

#6 – Memory/Historical Data

Having a model with a large amount of memory is key for complex jobs with lots of measurements, but is not an issue for small jobs.

#7 – Battery life

Most models need to have their batteries recharged or replaced every two to four hours, meaning spare batteries and/or portable chargers are essential.

Conclusion

The best thing about laser tape measures is their ability to perform many different tasks, so that simply calling these machines “laser tape measures” is a bit of a misnomer. “Laser measuring and calculating device” would be a more precise term, as they not only measure but use those measurements to make complex calculations instantly.

No more scribbling out equations on your notepad- simply make the measurements and let the machine do the rest. If you have some technology resistant friends who ridicule relying on machines for things older generations had to do themselves, let them talk while you work quicker and more accurately thanks to your laser tape measure. Let your results do your talking for you.
