Laser Level Features and Considerations

A laser level is a time-saving tool you can add to your tool kit, especially if you want to keep your projects accurate. The laser level buying guide will help you choose a tool that performs every task you need without overspending on a device you might not use.

You will have to consider several factors such as the size of your working space, the projects you intend to do, budget, and much more when looking for the best laser level that suits your needs.

We have pointed out some of the most important factors in our buying guide to enable you to narrow down your choices.


The first question you should ask yourself is how you intend to use your laser level. You should consider the tasks you’ll be using your tool to ensure you check all the options available on the market. This will help you avoid buying a tool you may not need. Some projects to give a thought include:

Single Line Applications

Some projects require one-line laser. If the job you plan to do is within this category, opt for single-line laser levels. They’re the least expensive and extremely useful.

A man uses a laser level on a home interior wall

Here are some tasks that require one-line laser:

  • Hanging art wall
  • Setting up shelves
  • Installing wall fixtures
  • Painting

Cross-Line Applications

These are tasks that require two perpendicular lines. This is time-saving and extremely useful when you are installing or building projects that require several elements to be accurate.

  • Here are some common uses for cross-line laser levels:
  • Wall and house framing
  • Custom closet installation
  • Suspended ceiling installation
  • Custom cabinetry

Rotary Laser Applications

Some projects require precise lines to be projected across large spaces. For such tasks, a rotary laser is a perfect device to use. Rotary laser levels are usually used on municipal-scale projects.

However, smaller contractors and builders can use them for landscaping, wiring and big framing tasks.

  • Here are some examples of rotary laser level applications: 
  • Large-scale residential framing
  • Machine-mounted control
  • Industrial and municipal excavation
  • Commercial building

Range Requirements

After deciding the type of laser level that will suit your applications best, you will need to determine the range you’ll require. This will depend on the size of your job site. Bear in mind that the work of a laser level is to project beams of light.

This means it is very easy to see laser levels in dark settings than in bright conditions. Glasses can help you view the line in bright places. However, you will have to consider using a laser sensor/receiver if you perform your work outdoors in bright locations.

Some lasers come with a receiver while others do not have them. Ensure you choose a laser with a receiver as a separate accessory if a receiver is one of the requirements you’re looking for. It should be from the same manufacturer to avoid having compatibility issues.

Here is an overview of the operating ranges. Range varies by model and manufacturer, so check well to ensure the laser level you pick meets your preferred range requirements.

TypeRange Range with Sensor
Single Line Laser Level 10 to 25 feet N/A
Cross-Line Laser Level 25 to 100 feet 150 to 250 feet
Rotary Laser Level 250 to 500 feet 1000 to 2500 feet

Some projects require measurements that are perfect, while others do not. If you are constructing custom cabinetry or laying tile, you should be accurate. However, nobody will notice you are off by ¼ an inch if you are constructing a chicken coop or framing a wall.

Basically, you get what you pay for when it comes to how precise a laser level is. Some of the single-line laser levels with low range may be out of level by ½ an inch at 10 feet. This is okay if you’re painting a stripe on the wall.

Crossline lasers are more precise. Most standard models have an accuracy of 1/8 inch at 30 feet. The Rotary laser levels are the most accurate. Some models boast an accuracy of 1/16 inch at 100 feet.

However, you should bear in mind that some maintenance is required in order to maintain optimal accuracy. You will need to run a built-in calibration function periodically that some laser levels have.

Others have a calibration service that will require you to take the device to a service center annually. If accuracy is your main concern, choose a model that has a reliable calibration option.

Ease of Use

There can be some big differences in how the laser level is operated depending on the type of tool you select. It is easy to work some laser levels with just a single or two buttons.

Other lasers are equipped with features that require you to adjust the settings whenever you want to use the tool. Your overall satisfaction will be affected if you find the laser level difficult to use.   

Some of the factors to consider when selecting your tool include:

  • Power level indicator
  • Power source
  • Manual override for custom angles and slopes
  • Self-leveling functionality
  • Automatic pendulum locking
  • Out of level indication

This will help you choose a laser that works well for you.

Power Source (Alkaline, Lithium, Nickel or 120V AC)

This may not be an issue for many users. However, you should not overlook it, especially if you perform your projects at remote job sites. Most builders and contractors like using a rechargeable battery. 

For some users, the battery that powers their laser level is the most important factor to focus on when deciding on the tool to buy. Consequently, some people will purchase lasers that are compatible with Bosch’s 12 volt or 18 volt batteries. Others will standardize on Dewalt’s 20 volt battery.

Unfortunately, you may not find a laser level that will work with your power sources. We have featured this factor in our buying guide to help you consider this when looking for a laser level.

Standard Alkaline Batteries

Alkaline reusable batteries are the most common power source for laser levels. Many popular rotary laser levels use D or AA batteries while cross line lasers use AA. This can be an inconvenience if you are not used to carrying around backup D batteries.

Find out if the manufacturer offers information concerning battery life then compare it against the duration of your project. If you require more power, it will make sense to invest in rechargeable batteries for your device.

OEM Rechargeable Batteries

A few lasers come with rechargeable OEM batteries, typically nickel-metal hydride (NiMH) or nickel-cadmium (NiCd). While you may prefer these batteries for other tools, note that they aren’t interchangeable. So, your backup power supply may not be of any help.

If you still choose a laser level that has an OEM rechargeable battery, consider buying another battery to avoid running into downtime when you need to recharge your battery.

120 Voltage AC Power

We have come across some laser levels that provide a standard AC power source for plugging in. This might be a good or a bad option depending on the type of jobs you do. Get more information about how the configuration works from the manufacturer if this is something you’re looking for.

Some lasers provide an AC power source as an added accessory. However, they don’t mention that you have to buy an OEM rechargeable battery so as to use the AC power source. 

Safety Considerations

It is safe to operate laser levels. However, you may need to think about some considerations, especially when working on tasks where people are present. The real concern for you involves the risk of fire and direct contact of the tool with your skin or eyes. 

Laser power is usually classified as Class I, II, III, or IV depending on the hazard and power they present.

Fortunately, most of the lasers available on the market fall within Class II or Class III. This means you are not exposed to any dangers. Class II laser levels have an output power that doesn’t exceed one milliwatt. However, they have a risk of eye damage which occurs when you stare into the beam for a long time.

It is important to note that continuous exposure to the beam can cause a burn in your retina. Class III laser levels that are used in rotary lasers also have warning labels. They can damage your eyes if the beam directly enters your eyes. Their output power doesn’t exceed 5 milliwatts.   

Warranty and Durability

Laser levels are fragile tools with sensitive components, just like other electronic devices in your arsenal. Some manufacturers claim their devices can survive 3 feet fall without affecting the laser level’s accuracy. However, you should handle your tool with a lot of care. 

There are some considerations you should bear in mind since this is a tool you’ll be using in some tough conditions.

  1. ​Check the manufacturer’s warranty. This will help you buy a laser level that comes with a warranty that covers the abuse your tool may experience.
  2. Consider the conditions you are frequently exposed to at your project site. For instance, if moisture and dust are common in your site, pick a laser level that has an IP rated enclosure.
  3. You do not have to worry about your enclosure if you work indoors in a workshop that is clean or has a dust extractor. However, opt for a rated enclosure if your job involves places with dust, mud, or rain.

Laser Color 

Most outdoor and indoor lasers emit red laser beams that make it difficult to see in worksite conditions which are brightly lit. As a result, manufacturers have resorted to designing brighter green lasers that can be spotted easily even under the sun.

The following are the advantages of both red and green beams:

  • Green beams offer up to 300 times more power making them great for heavy-duty projects.
  • Red beams, on the other hand, are sufficient for most indoor jobs. They also consume less power.

If your job involves indoor projects, a red beam will be sufficient for you while green beams will be a good option if you intend to do high-end tasks.

Warning Indicator and Power Level

If you intend to buy a battery-operated laser, ensure it is equipped with a power level to let you know the remaining battery run time. This will enable you to recharge your laser in advance.

The tool should also have a warning indicator to alert you when something is wrong. Some tools shut down when they encounter something while others show an audio warning sign.

Wrap Up

Laser levels have many uses; hence, a must-have tool for homeowners and professionals. These tools can help you accomplish commercial or DIY home improvement tasks where alignments are a must. They are also great for jobs that require precision and accuracy.

If you are a professional builder, laser levels are an excellent long-term investment because you’ll keep using them for different types of jobs. Use our buying guide to help you select the best laser level that suits your needs.
