What is a laser level? 

A laser level is an electric power tool that is mostly used by construction workers. It projects a red or green beam to measure the levelness. The beam can be a vertical or horizontal line, or can be both. Place a laser level in the middle of a room and when it projects a horizontal line on the walls, the length of the line on all sides from the floor will be equal.

The best laser level can be used for any activities that require leveling from a single reference point, including squaring, leveling, and other carpentry.

Especially, when you  have a DIY project at home, you can use a small laser level. The bigger ones, on the other hand, will be useful at outdoor and construction sites.

How to use a laser level? 

Not only can you use a laser level to check if the roof and/or ceiling is flat, but you can also make sure your furniture is placed on a flat surface when moving them around. In addition to that, you can apply the best laser level when you align walls, cabinets, chair rails and shelves, or check heights of the door, ceiling, and roof. You can also use it for ground surveying, wainscoting, drop ceilings and chair rails installations. It is multipurpose.

In order to use a laser level,  you need to follow these steps:

Step 1: Buy the best laser level and set it up

First and foremost, you need to choose a good quality laser level and then set it up on a flat surface. Some types of laser level include a tripod, and it is the best to use with it.

If you are using a manual one, you need to make sure that the bubbles are in the middle. You can turn the screws near the vial to get them in the right position. Then turn on the level and use.

Set up your laser level before using

If you are using a self-leveling one, it takes a few seconds for it to level itself. Some products will alert you with a blinking light if it is out of level. If that happens, you need to adjust the unit. Then turn on the level and use.

You might need a wall so that the laser beam can reflect on. If you don’t have one, use a laser detector to find the beam instead. 

Step 2: Start your projects with a laser level

  • Hanging objects with a laser level

If you want to hang a picture on the wall, firstly you need to determine the height of the picture frame that you want. Then put a small mark on the wall. Next, turn on the laser level and align it horizontally with the mark until it is level. Then you need to measure the length from the top of the frame to the hanging mechanism. Use this length to measure from laser downwards. Afterwards, make a mark on the wall, punch a nail at the mark and place the picture frames. You can use the laser to check for alignment at the top. 

  • Install wall tiles with a laser level

If you want to use the floor as a base for wall tiles and get your tiles in perfect position, you can use a laser level. First, choose a point on your wall, the distance from the floor to this point is shorter than the height of a tile. Then use your laser level and align the horizontal line to that point. Next, line up the laser line with the end of a straight board (2 inch wide) and screw the board to the wall. After resting your tiles on top of the board to make the first row, you can put more tiles up on the wall. You can remove the baseboard when all the tiles are securely installed. If you want to keep consistent grout lines, custom-cut tiles for the bottom row.

Different types of laser levels

As there are different types of laser levels in the market, you need to know exactly what they are in order to determine which one that you need.

#1: Dot Lasers/ Plumb Lasers

The dot laser level is basically just like the name of it. It casts a dot of light on the work surface. The laser can project a single or multiple dots with different shapes. They can be level, plumb or square. Its functions are similar to a water level and a plumb bob, however, it works more accurately for longer distances. 

Compared to other types of laser levels, dot lasers have shorter ranges. Although they are perfect for a reference point, it might be difficult to use them for any other purpose. Price ranges of dot lasers vary. So depending on your purpose, you know which one you should get. For example, if you use them for indoor activities, get a cheap one.

#2: Line Lasers

Line lasers are more common. They project a straight line from one point to the other. Some models of the laser line level can project multiple lines, which means that you can check for both straightness and squareness. You can mount them on ladders or a regular camera tripod. They are ideal for indoor use and can be difficult to see in bright light. However, there are new models that are equipped with better led diodes, therefore, you can use them outdoors.

#3: Rotary Laser Levels

Rotary lasers are as efficient as line lasers, although they are not as popular. They project a level line which rotates around the room in 360 degrees. In addition to the single line generator, they also come with the plumb up and plumb down capabilities.

Users can remote-control rotary laser levels which is very convenient. This type of laser level is highly accurate and is designed for outdoor work. For example, it can be ideally used when you want to lay foundations and pipes or grading roads. Because rotary laser levels are powerful, they are also more expensive. Also, given how big it is, you will need to use a sturdier base, or even a platform or a tractor to mount it. 

Laser level buying guide

When buying the best laser level, you can be confused. Below are some important factors that you need to consider:

Accuracy and Visibility Range

When it comes to accuracy of a laser level, it means that it has the ability to determine the leveling of a targeted surface by a fraction of an inch. If it is more accurate, it will be a better one. For example, a laser level with an accuracy rating of + 1/8in is more accurate than those with +5/16in.

On the other hand, the visibility range is the distance that the naked eye can see the laser. If it has the longer visibility range, it can work with the larger work surfaces.

If your laser can be seen up to 50 feet indoors, you can use it for small to mid-scale construction sites. If you are working on a large-scale construction site, you will need a higher visibility tool.

Battery Level

The main factors that you need to check from a good quality battery are runtime, life cycle, Amp-hour rating, and Voltage. 

Run-time refers to how long the battery will last on one charge. Some models have their battery last for up to 30 hours.

Life cycle refers to how many times the battery can be recharged before it goes bust. That means if your battery has a greater life cycle, it will be more rechargeable. 

Amp-hour rating refers to how much time the battery will last.

And Voltage refers to the working power of the level. The more voltage your battery provides, the brighter its beam will be. Also, remember that the voltage has no effect on the range of the tool.

Laser Color

There are two main laser colors, the red and the green one. Users of laser level have different opinions on them. Some of them prefer red beams, others opt for a green beam laser. So, what are the differences? First, red beams are ideal for almost all indoor tasks as they consume less power. Meanwhile, green beams are perfect for  heavy-duty jobs because they provide up to 300 times more power.

With that being said, if you are doing indoor tasks, you can use a red beam. On the other hand, you should opt for green beams if you want to do some high-end stuff.

Ease of Use

No matter which laser level you choose, the next model will always be more upgraded. Normal lasers have one or two buttons which make them less complicated to use, while other advanced ones need you to configure their settings before using them. So the best laser level is the one that has a few buttons, so that it will be easy for you to use. 

High IP Rating

IP Rating (Ingress Protection Rating) tells the ability of the tool’s sealing to protect it from the intrusion of dust and water. Therefore, the higher the IP Rating is, the more durable the laser level is. However, this factor doesn’t matter if you’re using your laser level for indoor projects.

Multiple Mounting Threads

If your laser level has different mounting options, it will be the best laser level.  With multiple threads, you can mount it on different types of surfaces. 

Some laser levels can be mounted on a standard tripod. If you want your laser level to be mounted in both indoor and outdoor settings, opt for multiple mounting threads one. 

Auto Leveling Capability

This is a common feature which automatically sets up your device within its leveling range. The compensator helps keep the line of sight of the tool horizontal, even when the laser unit isn’t level.


As you can see, laser levels are essential for jobs that require accuracy and precision. Using this tool not only helps you save time, but also your money. If you are working in the construction field, investing in the best laser level which is multipurpose is worth your money. Additionally, it can also be used when you work at home for DIY projects. Therefore, with the list we provide, hopefully you have chosen the best laser level for your needs.
